Purge out the old leaven, that you may be a new paste, as you are unleavened. For Christ our pasch is sacrificed.

“Let us not, therefore, be insensible to His kindness. For were He to reward us according to our works, we should cease to be. For "if Thou, Lord, shalt mark iniquities, O Lord, who shall stand?" Let us therefore prove ourselves worthy of that name which we have received. For whosoever is called by any other name besides this, he is not of God; for he has not received the prophecy which speaks thus concerning us: "The people shall be called by a new name, which the Lord shall name them, and shall be a holy people." This was first fulfilled in Syria; for "the disciples were called Christians at Antioch," when Paul and Peter were laying the foundations of the Church. Lay aside, therefore, the evil, the old, the corrupt leaven, and be ye changed into the new leaven of grace. Abide in Christ, that the stranger may not have dominion over you. It is absurd to speak of Jesus Christ with the tongue, and to cherish in the mind a Judaism which has now come to an end. For where there is Christianity there cannot be Judaism. For Christ is one, in whom every nation that believes, and every tongue that confesses, is gathered unto God.”

“Wherefore also Plato says, in the second book of the Republic, "It is those that sacrifice not a sow, but some great and difficult sacrifice," who ought to inquire respecting God. And the apostle writes, "Christ our passover was sacrificed for us;"-a sacrifice hard to procure, in truth, the Son of God consecrated for us.”

“Which prediction was thus also fulfilled, that "on the first day of unleavened bread" you slew Christ; and (that the prophecies might be fulfilled) the day hasted to make an "eventide,"-that is, to cause darkness, which was made at mid-day; and thus "your festive days God converted into grief, and your canticles into lamentation.”

“It does not matter that he also said, "For the destruction of the flesh, that the spirit may be saved in the day of the Lord," since both in the destruction of the flesh and in the saving of the spirit there is, on His part, judicial process; and when he bade "the wicked person be put away from the midst of them," he only mentioned what is a very frequently recurring sentence of the Creator. "Purge out the old leaven, that ye may be a new lump, as ye are unleavened." The unleavened bread was therefore, in the Creator's ordinance, a figure of us (Christians). The unleavened bread was therefore, in the Creator's ordinance, a figure of us (Christians). "For even Christ our passover is sacrificed for us." But why is Christ our passover, if the passover be not a type of Christ, in the similitude of the blood which saves, and of the Lamb, which is Christ? Why does (the apostle) clothe us and Christ with symbols of the Creator's solemn rites, unless they had relation to ourselves? When, again, he warns us against fornication, he reveals the resurrection of the flesh.”

“And for this reason three seasons of the year prefigured the Saviour Himself, so that He should fulfil the mysteries prophesied of Him. In the Passover season, so as to exhibit Himself as one destined to be sacrificed like a sheep, and to prove Himself the true Paschal-lamb, even as the apostle says, "Even Christ," who is God, "our passover was sacrificed for us." And at Pentecost so as to presignify the kingdom of heaven as He Himself first ascended to heaven and brought man as a gift to God.”

“The voice of the warning apostle is, "Purge out the old leaven, that ye may be a new lump, as ye are unleavened; for even Christ our passover is sacrificed. Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth." But are sincerity and truth preserved, when what is sincere is polluted by adulterous colours, and what is true is changed into a lie by the deceitful dyes of medicaments? Your Lord says, "Thou canst not make one hair white or black; " and you, in order to overcome the word of your Lord, will be more mighty than He, and stain your hair with a daring endeavour and with profane contempt. With evil presage of the future, you make a beginning to yourself already of flame-coloured hair; and sin (oh, wickedness!) with your head-that is, with the nobler part of your body! And although it is written of the Lord, "His head and His hair were white like wool or snow," you curse that whiteness and hate that hoariness which is like to the Lord's head.”

“That he who has attained to trust, having put off the former man, ought to regard only celestial and spiritual things, and to give no heed to the world which he has already renounced... Also in the same place: "Love not the world, neither the things that are in the world. If any man loveth the world, the love of the Father is not in him. Because everything which is in the world is lust of the flesh, and lust of the eyes, and the ambition of this world, which is not of the Father, but of the lust of this world. And the world shall pass away with its lust. But he that doeth the will of God abideth for ever, even as God abideth for ever." Also in the first Epistle of Paul to the Corinthians: "Purge out the old leaven, that ye may be a new dough, as ye are unleavened. For also Christ our passover is sacrificed. Therefore let us celebrate the feast, not in the old leaven, nor in the leaven of malice and wickedness, but in the unleavened bread of sincerity and truth."”

“"Purge out the old leaven," that is, this evil one. Not that he speaketh concerning this one only; rather he glances at others with him. For, "the old leaven" is not fornication only, but also sin of every kind. And he said not, "purge," but "purge out;" "cleanse with accuracy so that there be not so much as a remnant nor a shadow of that sort." In saying then, "purge out," he signifies that there was still iniquity among them. But in saying, "that ye may be a new lump, even as ye are unleavened," he affirms and declares that not over very many was the wickedness prevailing. But though he saith, "as ye are unleavened," he means it not as a fact that all were clean, but as to what sort of people you ought to be. "For our Passover also hath been sacrificed for us, even Christ; wherefore let us keep the feast: not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth." So also Christ called His doctrine Leaven. And further he himself dwells upon the metaphor, reminding them of an ancient history, and of the Passover and unleavened bread, and of their blessings both then and now, and their punishments and their plagues. It is festival, therefore, the whole time in which we live. For though he said, "Let us keep the feast," not with a view to the presence of the Passover or of Pentecost did he say it; but as pointing out that the whole of time is a festival unto Christians, because of the excellency of the good things which have been given. For what hath not come to pass that is good? The Son of God was made man for thee; He freed thee from death; and called thee to a kingdom. Thou therefore who hast obtained and art still obtaining such things, how can it be less than thy duty to "keep the feast" all thy life? Let no one then be downcast about poverty, and disease, and craft of enemies. For it is a festival, even the whole of our time. So that by means of this example also he mightily drives the fornicator out of the Church. For, saith he, so far from his presence profiting, he even doth harm, injuring the common estate of the body. For one knows not whence is the evil savor while the corrupt part is concealed, and so one imputes it to the whole. Wherefore he urges upon them strongly to "purge out the leaven, that ye may be," saith he, "a new lump, even as ye are unleavened." "For our Passover hath been sacrificed for us even Christ." He said not, hath died, but more in point to the subject in hand, "hath been sacrificed." Seek not then unleavened bread of this kind, since neither hast thou a lamb of the same kind. Seek not leaven of this description, seeing that thine unleavened bread is not such as this. Thus, in the case of material leaven, the unleavened might become leavened, but never the reverse; whereas here there is a chance of the direct contrary occurring. This however he has not plainly declared: and observe his good sense. In the former Epistle he gives the fornicator no hope of return, but orders that his whole life should be spent in repentance, lest he should make him less energetic through the promise. For he said not, "Deliver him up to Satan," that having repented he might be commended again unto the Church. But what saith he? "That he may be saved in the last day." For he conducts him on unto that time in order to make him full of anxiety. And what favors he intended him after the repentance, he reveals not, imitating his own Master. For as God saith, "Yet three days, and Nineveh shall be overthrown," and added not, "but if she repent she shall be saved:" so also he did not say here, "But if he repent worthily, we will 'confirm our love towards him.'" But he waits for him to do the work that so he may then receive the favor. For if he had said this at the beginning he might have set him free from the fear. Wherefore he not only does not so, but by the instance of leaven allows him not even a hope of return, but reserves him unto that day: "Purge out (so he says) the old leaven;" and, "let us not keep the feast with old leaven." But as soon as he had repented, he brought him in again with all earnestness. But why does he call it "old?" Either because our former life was of this sort, or because that which is old is "ready to vanish away," and is unsavory and foul; which is the nature of sin.”

“He therefore calls the Law the shadow of these things while the image and its characteristics are the mysteries celebrated by the Christians, as for instance, the lamb offered in sacrifice—a type of the Passion of Christ, in accordance with what the Apostle Paul says: For Christ our Passover was sacrificed; and John the Baptist thus speaks: Behold the Lamb of God which taketh away the sin of the world. Then after this, for the Israelites of that time there was their deliverance from the destroying angel and from the bondage to Pharaoh; for us, our deliverance from the devil and from our bondage to the very burdensome law. Then for them, their passage through the sea and their sojourning in the wilderness, and the giving of the law and the setting up of the Tabernacle; for us, our passage through baptism and our sojourning in the Church, and the gift of the Holy Spirit. For them, a copious supply of water from the rock to sustain their life; for us, the life-giving mysteries; for them, the land of promise as a place of rest; for us, heaven not made with hands as our place of rest; for them, temporal life; for us, life eternal and righteousness, and sanctification, and redemption and blessedness.”

“Above, the Apostle recalled a twofold fault: namely, that of the fornicating Corinthian, and of the others who were tolerating his sin; here he rebukes both faults. First, the fault of those tolerating his sin; second, the fault of the fornicator, there: "the body however is not for fornication," etc. Concerning the first he does two things. First, he rebukes in the Corinthians the negligence of judgment; second, he rebukes in them certain other vices concerning judgment, chapter VI: "does anyone dare," etc. Concerning the first he does two things. First, he rebukes those who did not separate the fornicator from themselves; second, he refutes the false understanding which they had conceived from his words, there: "I wrote to you in the epistle," etc. Concerning the first he does two things. First, he reproves what they had done; second, he shows what is to be done, there: "purge out the old leaven," etc. Concerning the first he does two things. First, he reproves the past fault as to its root. For he had said above that from their being puffed up there follows in them a lack of compassion, and from the lack of compassion, negligence of correction. First, therefore, he argues against the elation of the Corinthians, saying, "your boasting is not good," namely, by which you boast in the defects of others, as though you yourselves were innocent. For each one ought to glory in the Lord concerning the goods divinely given to himself, not concerning others, according to that word of Gal. VI, 4: "but let each one prove his own work, and so he will have glory in himself, and not in another." But it is especially evil to glory in the evils of others. For it is said in Ps. LI, 3: "why do you glory in malice?" Second, he assigns the reason for what he had said, saying, "do you not know that a little leaven corrupts the whole lump?" As if to say: you cannot be ignorant of this. Now it must be known that two things can be considered in leaven. First, the flavor which it gives to the bread, and according to this, by leaven is signified the wisdom of God, through which all the things that belong to man are made flavorful; and according to this it is said in Matth. XIII, 33: "the kingdom of heaven is like leaven, which a woman took and hid in three measures of flour, until the whole was leavened." Second, corruption can be considered in leaven, and according to this, by leaven can be understood, in one way, sin, because indeed through one sin of a man all his works are rendered corrupt, as for instance through the sin of pretense, which is compared to leaven. Lc. XII, 1: "beware of the leaven of the Pharisees, which is hypocrisy." In another way, by leaven can be understood the sinful man, and it is to this that this comparison is brought in. For just as through a little leaven the whole mass of dough is corrupted, so through one sinner the whole society is defiled. Hence Eccli. XI, 34: "from one spark the fire is increased, and from one deceitful man blood is increased." And this indeed happens, when through the sin of one, others are in some way provoked to sin. Or also when they consent to the one sinning, at least by not correcting him when they are able to correct, according to that word of Rom. I, 32: "they are worthy of death, not only they who do these things, but also they who consent to those doing them." And therefore the Corinthians ought not to glory in the sin of one, but rather to take care lest, through the sin of one, all be defiled by association with him, according to that word of Cant. II, 2: "as the lily among thorns, so is my beloved among the daughters," where the Gloss says: "he was not good, who could not tolerate the wicked." Then, when he says, "purge out the old leaven," he shows what is to be done for the rest. And first he sets down the teaching; second he assigns the reason, there: "our Passover," etc. He says therefore first: because "a little leaven corrupts the whole lump," therefore "purge out the old leaven," that is, purge yourselves, by casting away from you the old leaven, that is, the fornicator, who by sinning has returned to the oldness of ancient corruption, according to that word of Baruch III, 11: "you have grown old in a foreign land, you have been defiled with the dead." Which indeed he says, because through the separation of one sinner the whole society is purged. Hence also, when Judas had gone out, the Lord said, Io. XIII, 31: "now is the Son of man glorified." By the old leaven can also be understood ancient error, according to that word of Is. XXVI, 3: "the old error has departed," or also the corruption of original sin, according to that word of Rom. VI, 6: "our old man has been crucified together with him," or also any actual sin whatsoever, according to that word of Col. III, 9: "stripping yourselves of the old man with his deeds": for by the admonition of these a man is purged. He then sets down consequently the effect of the purging, saying, "that you may be a new mixture." Now "mixture" is said to be the commingling of water and new flour, before leaven is mixed in. Therefore, with the leaven removed from the faithful, that is, the sinner, or the sin, they remain as a new mixture, that is, in the purity of their newness, according to that word of Ps. CII, 5: "your youth will be renewed like the eagle's"; Eph. IV, v. 23: "be renewed in the spirit of your mind." Then he sets down the due manner of the purging when he says, "as you are unleavened," that is, without the leaven of sin. For it is said from "a," which is "without," and "zyma," which is "leaven." Hence the Lord, Matth. XVI, 6, says to the disciples, "beware of the leaven of the Pharisees and Sadducees." Then, when he says, "for indeed our Passover," he assigns the reason for what he had said, namely why the faithful ought to be unleavened, which reason indeed is taken from the mystery of Christ's passion. Hence first he sets forth the mystery itself; second he concludes his proposition, there: "therefore let us feast," etc. Concerning the first it must be considered that among the other sacraments of the law the most celebrated was the paschal lamb, which, as is commanded in Ex. XII, 1 ff., was immolated by the whole multitude of the sons of Israel in memory of that benefit, by which the Angel striking the firstborn of Egypt passed over the houses of the Jews, whose doors had been smeared with the blood of the lamb. Hence the name of Pasch is taken, according to what is said there: "for it is the phase," that is, "the passing over of the Lord"; and finally by the power of this benefit the people crossed the Red Sea, as is said in Ex. XIV, 15 ff. For that lamb was a figure of the innocent Christ, of whom it is said, Io. I, 29: "behold the Lamb of God." Therefore, just as that figural lamb was immolated by the sons of Israel, that the people of God might be freed from the striking Angel, and that they might cross the Red Sea, freed from the servitude of Egypt, so Christ was slain by the sons of Israel, through whose blood the people of God is freed from the assault of the Devil and from the servitude of sin, through Baptism as through the Red Sea. That figural lamb, however, was called the Pasch of the Jews, because it was immolated as a sign of the passing over. Hence it is said, Matth. XXVI, 17: "where do you wish that we prepare for you to eat the Pasch?" That is, the paschal lamb. The Apostle says therefore: for this reason you ought to be unleavened, "for indeed," that is, because, just as the figural Pasch of the old people is the lamb immolated, so "our Passover," that is, of the new people, "is Christ, immolated," to whose immolation also the name of Pasch is fitting, both by the signification of the Hebrew tongue, which signifies passing-over, Ex. XII, 11: "for it is the phase," that is, "the passing over," and by the signification of the Greek tongue, insofar as the name Pasch signifies passion. For Christ, through the passion by which he was immolated, passed over from this world to the Father, as is said in Io. XIII, 1. Then, when he says, "therefore let us feast," he concludes his proposition. For the evidence of this it must be considered that, as is read in Ex. XII, 8, the paschal lamb after its immolation was eaten with unleavened breads. Therefore, just as the figural lamb was a figure of our immolated Passover, so the figural paschal observance ought to be conformed to the observance of the new Passover. Therefore, because Christ immolated is our Passover, "therefore let us feast," namely, eating Christ, not only sacramentally, according to that word of Io. VI, v. 54: "unless you eat the flesh of the Son of man, and drink his blood, you will not have life in you," but also spiritually, by enjoying his wisdom, according to that word of Eccli. XXIV, v. 29: "they who eat me shall still hunger, and they who drink me shall still thirst," and thus with spiritual joy, according to that word of Ps. XLI, 5: "with the voice of exultation and confession, the sound of one feasting." Then he determines the manner of feasting according to the conformity of the truth to the figure, saying, "not in the old leaven, nor in the leaven of malice and wickedness." For it was commanded in Ex. XII, 15, that no leaven at all should be found in the houses of those eating the paschal lamb. Leaven, however, has both oldness and corruption. Hence by the removal of leaven, first indeed can be understood the removal of the observance of the precepts of the old law, which through the passion of Christ has been put to death, according to that word of Lev. c. XXVI, 10: "you will cast away the old things, when the new come upon you." Second, by the removal of leaven can be understood the removal of the corruption of sin, as was said above, that "a little leaven corrupts the whole lump." And as to this he adds, "nor in the leaven of malice and wickedness," so that malice is referred to the perversity of the deed, according to that word of Iac. I, v. 21: "casting away all filthiness and abundance of malice." By wickedness, however, is understood fraudulent scheming. Prov. XXVI, v. 25: "when he shall have taken up his voice, do not believe him, for there are seven wickednesses in his heart." Or, according to the Gloss, when he says, "not in the old leaven," he removes the oldness of sin in common. But what he adds, "nor in the leaven of malice and wickedness," explains sin part by part, so that malice is said to be the sin which is committed against oneself, wickedness the sin which is committed against another. Having therefore excluded the undue manner of feasting, he determines the fitting manner, adding, "but in the unleavened bread of sincerity and truth," that is, in sincerity and truth, which are signified by the unleavened bread. Now sincerity is set against the corruption of sin, which he signified when he said, "not in the leaven of malice and wickedness." For that is called sincere which is without corruption. Hence in II Cor. II, 17 it is said: "we are not like many, adulterating the word of God, but from sincerity we speak in Christ." Truth, however, is set against the figures of the old law, as in Io. I, v. 17 it is said, "truth and grace was made through Jesus Christ," because indeed we ought to celebrate the true Passover with truth and not with figures. Hence, according to the Gloss, by sincerity is understood innocence from vices, or newness of life; by truth, however, the justice of good works, or rectitude, which excludes fraud.”

“Here the apostle exhorts them to purity, by purging out the old leaven. In this observe, I. The advice itself, addressed either, 1. To the church in general; and so purging out the old leaven, that they might be a new lump, refers to the putting away from themselves that wicked person, Co1 5:13. Note, Christian churches should be pure and holy, and not bear such corrupt and scandalous members. They are to be unleavened, and should endure no such heterogeneous mixture to sour and corrupt them. Or, 2. To each particular member of the church. And so it implies that they should purge themselves from all impurity of heart and life, especially from this kind of wickedness, to which the Corinthians were addicted to a proverb. See the argument at the beginning. This old leaven was in a particular manner to be purged out, that they might become a new lump. Note, Christians should be careful to keep themselves clean, as well as purge polluted members out of their society. And they should especially avoid the sins to which they themselves were once most addicted, and the reigning vices of the places and the people where they live. They were also to purge themselves from malice and wickedness - all ill-will and mischievous subtlety. This is leaven that sours the mind to a great degree. It is not improbable that this was intended as a check to some who gloried in the scandalous behaviour of the offender, both out of pride and pique. Note, Christians should be careful to keep free from malice and mischief. Love is the very essence and life of the Christian religion. It is the fairest image of God, for God is love (Jo1 4:16), and therefore it is no wonder if it be the greatest beauty and ornament of a Christian. But malice is murder in its principles: He that hates his brother is a murderer (Jo1 3:15), he bears the image and proclaims him the offspring of him who was a murderer from the beginning, Joh 8:44. How hateful should every thing be to a Christian that looks like malice and mischief. II. The reason with which this advice is enforced: For Christ our passover is sacrificed for us, Co1 5:7. This is the great doctrine of the gospel. The Jews, after they had killed the passover, kept the feast of unleavened bread. So must we; not for seven days only, but all our days. We should die with our Saviour to sin, be planted into the likeness of his death by mortifying sin, and into the likeness of his resurrection by rising again to newness of life, and that internal and external. We must have new hearts and new lives. Note, The whole life of a Christian must be a feast of unleavened bread. His common conversation and his religious performances must be holy. He must purge out the old leaven, and keep the feast of unleavened bread of sincerity and truth. He must be without guilt in his conduct towards God and man. And the more there is of sincerity in our own profession, the less shall we censure that of others. Note, On the whole, The sacrifice of our Redeemer is the strongest argument with a gracious heart for purity and sincerity. How sincere a regard did he show to our welfare, in dying for us! and how terrible a proof was his death of the detestable nature of sin, and God's displeasure against it! Heinous evil, that could not be expiated but with the blood of the Son of God! And shall a Christian love the murderer of his Lord? God forbid.”

“Purge out therefore the old leaven,.... Meaning either the incestuous person, whose crime might well be compared to sour "leaven", and be called old because of his long continuance in it; whom the apostle would have removed from them; this is properly the act of excommunication, which that church was to perform, as a quite distinct thing from what the apostle himself determined to do. The allusion is to the strict search the Jews made (g), just before their passover after leaven, to purge their houses of it, that none of it might remain when their feast began; which they made by the light of a lamp, on the night of the fourteenth of the month Nisan, in every secret place, hole, and corner of the house: or this may be an exhortation to the church in general with respect to themselves, as well as this man, to relinquish their old course of sinning, to "put off concerning the former conversation the old man", Eph 4:22 the same with the old leaven here; it being usual with the Jews (h) to call the vitiosity and corruption of nature , "leaven in the lump"; of which say (i), "the evil imagination of a man, as leaven the lump, enters into his bowels little, little, (very little at first,) but afterwards it increases in him, until his whole body is mixed with it.'' That ye may be a new lump; that they might appear to be what they professed to be, new men, new creatures in Christ, by their walking in newness of life; and by removing that wicked person, they would be as the apostles were, when Judas was gone from them, all clean through the word of Christ: as ye are unleavened; at least professed to be. They were without the leaven of sin; not without the being of sin in their hearts, nor without the commission of it, more or less, in their lives; but were justified from it by the righteousness of Christ, and had the new creature formed in their souls, or that which was born of God in them, that sinned not. The apostle compares the true believers of this church to the unleavened bread eaten at the passover, for the grace of their hearts, and the simplicity of their lives; as he does the incestuous man to the old leaven, that was to be searched for, and cast out at the feast: for even Christ our passover is sacrificed for us. This is observed, to show the pertinency of the similes of leaven and unleavened, the apostle had made use of; and to make some further improvement of them, for the use, comfort, and instruction of this church; saying, that Christ is "our passover", the Christians' passover; the Jewish passover was a type of Christ; wherefore Moses kept it by faith, in the faith of the Messiah that was to come; see Heb 11:28 as it was instituted in commemoration of the deliverance of the Israelites from Egypt, so likewise to prefigure Christ, and the redemption of his people by him. The Jews have a saying (k), "that in the month Nisan they were redeemed, and in the month Nisan they will be redeemed;'' which was the month in which the passover was kept; and for the confirmation of which, they mention the following texts, Mic 7:15. There is an agreement between the passover, and Christ, in the sacrifice itself, and the qualities of it; it was a "lamb", as Christ is the "Lamb" of God, of his appointing and providing, and fitly so called, for his innocence and harmlessness, his meekness, humility, and patience; it was a lamb "without blemish", as Christ is, without spot and blemish, without the spot of original sin, or blemish of any actual transgression: it was a male, as Christ is the son or man, the head of the body, and the "firstborn" among many brethren; it was a male of the first year; in which it might prefigure Christ in the flower of his age, arrived at man's estate, and having had experience of a variety of sorrows and afflictions. There is also some likeness between them in the separation and slaying of it. The passover lamb was to be "taken out from the sheep, or from the goats"; as Christ's human nature was chosen out from among the people, and, in God's eternal counsel and covenant, separated from the rest of the individuals of human nature, and taken into a federal union with the Son of God, and preordained before the foundation of the world, to be the Lamb slain; it was also wonderfully formed by the Holy Ghost in the virgin's womb, and separated and preserved from the infection of sin; and in his life and conversation here on earth, he was separated from sinners, from being like them, and is now made higher than the heavens. This lamb was kept up from the "tenth" of the month, to the "fourteenth", before it was killed; which might typify preservation of Christ, in his infancy, from the malice of Herod, and, in his riper years, from the designs of the Jews upon him, until his time was come; and it is to be observed, that there was much such a space of time between his entrance into Jerusalem, and his sufferings and death; see Joh 12:11. The lamb was "slain", so the Prince of life was killed; and "between the two evenings", as Christ was in the end of the world, in the last days, in the decline of time, of the age of the world, and even of the time of the day, about the "ninth" hour, or three o'clock in the afternoon, the time between the two evenings; the first evening beginning at noon as soon as the sun began to decline, the other upon the setting of it. There is likewise a comparison of these together to be observed, in the dressing and eating of it. The passover lamb was not to be eaten "raw nor sodden"; so Christ is to be eaten not in a carnal, but in a spiritual way, by faith; it was to be "roast with fire", denoting the painful sufferings of Christ on the cross, and the fire of divine wrath that fell upon him; it was to be eaten "whole", as a whole Christ is to be received by faith, in his person, and in all his offices, grace, and righteousness; not a "bone" of it was to be "broken", which was fulfilled in Christ, Joh 19:36 it was to be eaten "with unleavened bread", which is spiritualized by the apostle in the next verse; and also with "bitter herbs", expressive of the hard bondage and severe afflictions, with which the lives of the Israelites were made bitter in Egypt; and significative of the persecutions and trials that such must expect, who live godly and by faith in Christ Jesus: it was eaten only by Israelites, and such as became proselytes, as Christ, only by true believers; and if the household was too little, they were to join with their "neighbours"; which might typify the calling and bringing in of the Gentiles, when the middle wall of partition was broken down, Christ, his flesh and blood being common to both. The first passover was eaten in haste, with their loins girt, their shoes on, and staves in their hands, ready to depart from Egypt to Canaan's land; denoting the readiness of believers to every good work; having their feet shod with the preparation of the Gospel of peace; their loins girt about with truth, their lights burning, and they like men waiting for their Lord's coming; hasting unto the day of the Lord, being earnestly, desirous of being absent from the body, that they might be present with him: in a word, the receiving of the blood of the passover lamb into a bason, sprinkling it on the lintel, and two side posts of the doors of the houses, in which they ate it, which the Lord seeing passed over those houses, when he passed through Egypt to destroy the firstborn, whence it has its name of the passover, were very significative of the blood of sprinkling, even the blood of Christ upon the hearts and consciences of believers; whereby they are secured from avenging justice, from the curse and condemnation of the law, and from wrath to come, and shall never be hurt of the second death. Thus Christ is our antitypical passover, who was sacrificed, whose body and soul were offered as an offering and sacrifice unto God for us, that he might be proper food for our faith; and also in our room and stead, to make satisfaction to divine justice for all our sins and transgressions.

“Purge out therefore the old leaven - As it is the custom of the Jews previously to the passover to search their houses in the most diligent manner for the old leaven, and throw it out, sweeping every part clean; so act with this incestuous person. I have already shown with what care the Jews purged their houses from all leaven previously to the passover; see the note on Exo 12:8-19 (note), and on the term passover, and Christ as represented by this ancient Jewish sacrifice; see on Exo 12:27 (note), and my Discourse on the Nature and Design of the Eucharist.”

“old leaven--The remnant of the "old" (Eph 4:22-24) heathenish and natural corruption. The image is taken from the extreme care of the Jews in searching every corner of their houses, and "purging out" every particle of leaven from the time of killing the lamb before the Passover (Deu 16:3-4). So Christians are continually to search and purify their hearts (Psa 139:23-24). as ye are unleavened--normally, and as far as your Christian calling is concerned: free from the leaven of sin and death (Co1 6:11). Paul often grounds exhortations on the assumption of Christian professors' normal state as realized (Rom 6:3-4) [ALFORD]. Regarding the Corinthian Church as the Passover "unleavened lump" or mass, he entreats them to correspond in fact with this their normal state. "For Christ our Passover (Exo 12:5-11, Exo 12:21-23; Joh 1:29) has been (English Version, "is") sacrificed for us"; that is, as the Jews began the days of unleavened bread with the slaying of the Passover lamb, so, Christ our Passover having been already slain, let there be no leaven of evil in you who are the "unleavened lump." Doubtless he alludes to the Passover which had been two or three weeks before kept by the Jewish Christians (Co1 16:8): the Gentile Christians probably also refraining from leavened bread at the love-feasts. Thus the Jewish Passover naturally gave place to our Christian Easter. The time however, of keeping feast (metaphorical; that is, leading the Christian life of joy in Christ's finished work, compare Pro 15:15) among us Christians, corresponding to the Jewish Passover, is not limited, as the latter, to one season, but is ALL our time; for the transcendent benefits of the once-for-all completed sacrifice of our Passover Lamb extends to all the time of our lives and of this Christian dispensation; in no part of our time is the leaven of evil to be admitted. For even--an additional reason, besides that in Co1 5:6, and a more cogent one for purging out every leaven of evil; namely, that Christ has been already sacrificed, whereas the old leaven is yet unremoved, which ought to have been long ago purged out.”
