“Because all the nations that dwell under heaven were called by hearing and believing upon the name of the Son of God. Having, therefore, received the seal, they had one understanding and one mind; and their faith became one, and their love one.”

“"Lord, who hath believed our report?" Isaiah says. For "faith cometh by hearing, and hearing by the word of God," saith the apostle. "How then shall they call on Him in whom they have not believed? And how shall they believe on Him whom they have not heard? And how shall they hear without a preacher? And how shall they preach except they be sent? As it is written, How beautiful are the feet of those that publish glad tidings of good things!" You see how he brings faith by hearing, and the preaching of the apostles, up to the word of the Lord, and to the Son of God. We do not yet understand the word of the Lord to be demonstration.”

“For where had been their sin, if they only maintained the righteousness of their own God against one of whom they were ignorant? But he exclaims: "O the depth of the riches and the wisdom of God; how unsearchable also are His ways!" Whence this outburst of feeling? Surely from the recollection of the Scriptures, which he had been previously turning over, as well as from his contemplation of the mysteries which he had been setting forth above, in relation to the faith of Christ coming from the law. If Marcion had an object in his erasures, why does his apostle utter such an exclamation, because his god has no riches for him to contemplate? So poor and indigent was he, that he created nothing, predicted nothing-in short, possessed nothing; for it was into the world of another God that he descended.”

“"But they have not all obeyed the Gospel. For Esaias saith, Lord, who hath believed our report? So then faith cometh by hearing, and hearing by the word of God." Since they pressed him with another objection again to this effect, that if these were the persons sent upon the mission by God, all ought to have hearkened to them: observe Paul's judgment, and see how he shows that this very thing which made the confusion, did in fact do away with confusion and embarrassment. What offends you, O Jew, he would say, after so great and abundant evidence, and demonstration of the points? that all did not submit to the Gospel? Why this very thing, when taken along with the others, is of force to certify thee of the truth of my statements, even in that some do not believe. For this too the prophet foretold. Notice his unspeakable wisdom too; how he shows more than they were looking for, or expected him to have to say in reply. For what is it that you say? he means. Is it that all have not believed the Gospel? Well! Isaiah foretold this too from of old. Or rather, not this only, but even much more than this. For the complaint you make is Why did not all believe? But Isaiah goes further than this. For what is it he says? "Lord, who hath believed our report?" Then since he had rid himself of this embarrassment by making the Prophet a bulwark against them, he again keeps to the line he was before upon. For as he had said that they must call upon Him, but that they who call must believe, and they who believe must hear first, but they who are to hear must have preachers, and the preachers be sent, and as he had shown that they were sent, and had preached; as he is going to bring in another objection again, taking occasion first of another quotation from the Prophet, by which he had met the objection a little back, he thus interweaves it, and connects it with what went before. For since he had produced the Prophet as saying, "Lord, who hath believed our report"? he happily seizes on the quotation, as proving what he says, "So then faith cometh by hearing." And this he makes not a mere naked statement. But as the Jews were forever seeking a sign, and the sight of the Resurrection, and were gaping after the thing much; he says, Yet the Prophet promised no such thing, but that it was by hearing that we were to believe. Hence he makes this good first, and says, "so then faith cometh by hearing." And then since this seemed a mean thing to say, see how he elevates it. For he says, I was not speaking of mere hearing, nor of the need of hearing men's words and believing them, but I mean a great sort of hearing. For the hearing is "by the word of God." They were not speaking their own, but they were telling what they learnt from God. And this is a higher thing than miracles. For we are equally bound to believe and to obey God, whether speaking or working miracles. Since both works and miracles come of His words. For both the heaven and everything else was established in this way.”

“And for this reason also when our Lord gave us this blessing of perceiving Him, He delivered unto us first of all faith, with which we might perceive Him, and then He revealed to us concerning Himself, and for this reason the blessed Paul said that "Faith [cometh] from the hearing of the ear, and the hearing of the ear from the word of God." By the hearing of the word of God Paul taught us to receive faith, and although faith hath been implanted in our construction by God our Creator, yet hath it been corrupted and changed from faith to error, and after the manner of that natural wisdom which hath also been given to us in our construction we have changed it, and instead of the wisdom of God we have gathered together the wisdom of [this] world with it.”

“Faith comes by hearing, because when we hear the holy Scriptures we believe in the teaching of the Holy Spirit. This faith is made perfect by all the things which Christ has ordained; it believes truly, it is devout and it keeps the commandments of him who has renewed us. For he who does not believe in accordance with the traditions of the catholic church or who through untoward works holds communion with the devil is without faith.”

“After the Apostle had, in expounding the word of Moses, set down beforehand that confession of the mouth and faith of the heart work salvation—proposing this by way of example in two particulars, of which Moses seemed to have made mention—here he proves in universal terms what he had said. And concerning this he does three things. First he shows that through faith and confession man attains salvation; second he sets down the order of salvation, at the words how then shall they call upon, etc.; third he draws a certain conclusion from what has been said, at the words therefore faith is from hearing, and so on. Concerning the first he does three things. First he sets forth what he intends, saying: I rightly say that if you confess with your mouth and believe in your heart, you will be saved; for with the heart one believes, on man's part, unto righteousness, that is, unto this, that he may attain righteousness through faith. Above, chapter 5: being therefore justified from faith. He says pointedly with the heart one believes, that is, by the will. For as to the other things which pertain to the outward worship of God, a man can perform them unwillingly, but he cannot believe except willingly. For the intellect of the one believing is not determined to assent to the truth by the necessity of reason, as is the intellect of the one who knows, but by the will; and therefore knowing does not pertain to man's righteousness, which is in the will, but believing does. Genesis 15: Abraham believed God, and it was reputed to him unto righteousness. But after man has been justified through faith, it is necessary that his faith work through love in order to attain salvation. Hence he adds, but with the mouth confession is made unto salvation, namely, unto the attainment of eternal salvation. Isaiah 51: but my salvation shall be forever. Now there is a threefold confession necessary for salvation. First, indeed, the confession of one's own iniquity, according to Psalm 31: I said, I will confess against myself my injustice to the Lord, which is the confession of the penitent. The second confession is that by which man confesses the goodness of God who mercifully bestows benefits, Psalm 117: confess to the Lord, for he is good, and this is the confession of one giving thanks. The third is the confession of divine truth, Matthew 10: everyone who shall confess me before men, I also will confess him before my Father; and this confession is that of the believer, of which the Apostle now speaks. This, however, is necessary for salvation according to place and time, namely, when someone's faith is demanded, that is, by a persecutor of the faith, or when another's faith is endangered—just as prelates especially ought to preach the faith to their subjects. And for this reason the baptized are anointed with chrism on the forehead with the sign of the cross, so that they may not be ashamed to confess the Crucified himself. Above, chapter 1: for I am not ashamed of the Gospel. And so it is likewise with all the acts of the virtues, which are necessary for salvation according to place and time. For the affirmative precepts which are given concerning these things bind always, but not for always. Second, at the words for the Scripture says, etc., he proves it by authority, saying: for the Scripture says, namely Isaiah 28: whoever believes in him, namely with a formed faith, shall not be confounded, that is, as one falling short of salvation. Ecclesiasticus 2: you who fear the Lord, believe him, and your reward shall not be made void. Our text, however, has: he who shall have believed, let him not hasten, as was said above. Third, at the words for there is no distinction, etc., he proves that this is to be understood universally, since Isaiah proposes it without qualification. And first he sets forth what he intends, saying: therefore it was said whoever believes, etc., for there is no distinction in this regard between Jew and Greek. Colossians 3: where there is no Gentile and Jew, circumcision and uncircumcision, and so on. Second, he proves it by an argument which rests on two grounds, the first of which he touches when he says, for the same is Lord of all. Above, chapter 3: is he the God of the Jews only? Is he not also of the Gentiles? Psalm 46: God is king of all the earth. And therefore it belongs to him to provide for the salvation of all. He touches the second ground when he says, rich toward all who call upon him. For if he were not of such goodness as would suffice for the satisfaction of both, one might think that he would not provide for all believers; but the riches of his goodness and mercy are unfailing. Above, chapter 2: or do you despise the riches of his goodness? Ephesians 2: but God, who is rich in mercy, and so on. Third, he proves the same point by the authority found in Joel 2: whosoever shall call upon the name of the Lord shall be saved. Now to call upon is to call him into oneself through affection and devout worship. Psalm 90: he shall call upon me, and I will hear him. Then, at the words how then shall they call upon, etc., he sets down the order by which someone is called unto salvation, which is from faith. And concerning this he does two things. First he shows that the things which are later in this order cannot exist without the prior things; second he shows that, given the prior things, it is not necessary that the later things be given, at the words but not all obey the Gospel. Concerning the first he does two things. First he sets down the order of the things required for salvation; second he confirms what he had assumed by an authority, at the words as it is written. Now first he sets down five things in order, beginning from invocation, upon which, according to the authority of the prophet, salvation follows. He says therefore how then shall they call upon him in whom they have not believed? As if to say: without doubt invocation cannot bring about salvation unless faith precedes it. Now invocation pertains to confession of the mouth, which proceeds from faith of the heart. Psalm 115: I believed, therefore have I spoken. 2 Corinthians 4: we believed, therefore we also speak. Second, he ascends or proceeds from faith to hearing, saying, or how shall they believe him whom they have not heard? For a man is said to believe those things which are told him by others which he himself does not see. John 4: now we believe not for your saying, for we ourselves have heard, and know that this is indeed the Savior of the world, and so on. Now there is a twofold hearing: one indeed interior, by which someone hears from God revealing, Psalm 84: I will hear what the Lord God shall speak in me; the other, however, is a hearing by which someone hears from a man speaking outwardly. Acts, chapter 10: while Peter was yet speaking these words, the Holy Spirit fell upon all who heard the word. Now the first hearing does not pertain commonly to all, but properly pertains to the grace of prophecy, which is a grace freely given distinctly to some, but not to all, according to that saying, 1 Corinthians 12: there are divisions of graces. But since he is now speaking of that which can pertain indistinctly to all, according to what he said above, for there is no distinction, it remains that this is to be understood of the second hearing. And therefore he adds: how then shall they hear without a preacher? For exterior hearing is a certain passion of the hearer, which cannot exist without the action of one speaking. Hence also the Lord commanded his disciples, Matthew, last chapter: going into the whole world, preach the Gospel to every creature. But as for the things which are of faith, preachers do not have them from themselves, but from God. Isaiah 21: what I have heard from the Lord God of hosts I have declared to you. 1 Corinthians 11: for I have received of the Lord that which also I delivered unto you. And therefore the Apostle, fourth, adds, and how shall they preach unless they be sent? As if to say, not worthily. Jeremiah 23: I did not send them, and they ran. Now some are sent by the Lord in two ways. In one way, immediately by God himself through interior inspiration. Isaiah 48: and now the Lord God has sent me, and his spirit. Now the sign of this sending is sometimes indeed the authority of Sacred Scripture; hence John the Baptist, when he was asked who he was, adduced the authority of a prophet, saying: I am the voice of one crying in the desert, make straight the way of the Lord, as Isaiah the prophet said, as is read in John 1. Sometimes, however, the sign of this sending is the truth of the things announced. Hence, conversely, it is said in Deuteronomy 18 that this shall be the sign: that if a prophet shall foretell in the name of the Lord and it shall not come to pass, the Lord has not spoken this. Sometimes, indeed, the sign of this sending is the working of a miracle. Hence it is said in Exodus 4 that when Moses had said to the Lord: they will not believe me, nor hear my voice—namely, those to whom I am sent—the Lord gave him the power of working signs. Yet these last two do not sufficiently demonstrate a sending from God, especially when someone announces something contrary to the faith. For it is said in Deuteronomy 13: if there should arise in the midst of you a prophet, and he should foretell a sign and a wonder, and that should come to pass which he spoke, and he should say to you, let us go and follow strange gods, you shall not hear the words of that one. In the other way, some are sent by God through the mediation of the authority of prelates, who hold the place of God. 2 Corinthians 8: we have sent with him our brother, whose praise is in the Gospel throughout all the churches. Then, when he says as it is written, he brings in an authority to prove this last point, which he had said concerning the sending of preachers, saying as it is written, namely Isaiah 52: how beautiful are the feet of them that preach peace, of them that preach good things—where our text has it thus: how beautiful upon the mountains are the feet of him that preaches and announces peace, that announces good. And likewise it is found in Nahum 1: behold upon the mountains the feet of him that brings good tidings and announces peace. Now in these words, first, the progress of preachers is commended, when he says how beautiful are the feet, which can be understood in two ways. In one way, so that by feet is understood their progress, namely because they proceed in an orderly manner, not usurping to themselves the office of preaching. Canticles 7: how beautiful are your steps in your shoes, O daughter of a prince. In the other way, by feet can be understood the affections, which have rectitude, when they announce the word of God not with the intention of praise or gain, but for the sake of the salvation of men and the glory of God. Ezekiel 1: their feet, straight feet. Second, he touches on the matter of preaching, which indeed is twofold. For they preach those things which are useful for the present life, which he designates when he says: that preach peace, namely a threefold peace. First, indeed, they announce the peace which Christ made between men and God. 2 Corinthians 5: God was in Christ, reconciling the world to himself. And he has placed in us the word of reconciliation. Above, chapter 5: let us have peace with God through Jesus Christ. Second, they announce the peace to be had with all men. Below, chapter 12: if it be possible, as much as is in you, having peace with all men. Third, they announce those things by which a man can have peace within himself. Psalm 118: much peace have they that love your law, O Lord. And under these three are contained all the things which in this life are useful for salvation, whether with regard to God, or with regard to one's neighbor, or with regard to oneself. They also preach those things which we hope to have in the other life. And as to this he says, that preach good things. Luke 12: he shall set him over all his goods. Then, when he says but not all obey the Gospel, etc., he shows that from the prior things the later things do not always follow. For although it cannot be that someone believes unless he hears from a preacher, nevertheless not everyone who hears from a preacher believes, and this is what he adds, but not all obey the Gospel. 2 Thessalonians 3: for all men have not faith. Now he says this in order to show that the exterior word of the one speaking is not a sufficient cause of faith, unless the heart of the man is drawn interiorly by the power of God speaking, John 6: everyone who has heard from my Father, and has learned, comes to me. And thus that men believe is not to be attributed to the diligence of the preacher. By this also it is shown that not all unbelievers are excused from sin, but only those who do not hear and do not believe. John 15: if I had not come, and had not spoken to them, they would not have sin; but now they have no excuse for their sin. And this also is more consonant with what the Apostle will say afterward. Second, he brings in an authority for this, when he adds, for Isaiah says: Lord, who has believed our hearing? As if he were to say: few. Ezekiel 2: unbelievers and subverters are with you. Micah 7: I have become as one that gathers grapes in the autumn gleaning. This indeed Isaiah said, foreseeing the future unbelief of the Jews. Ecclesiasticus 48: he saw the last things by a great spirit, and so on. He says, moreover, our hearing, either on account of what they heard from God—as is said in Obadiah 1: we have heard a report from the Lord, and he has sent ambassadors to the nations—or on account of what men heard from the apostles. Ezekiel 33: they hear your words, and do them not. Then, when he says therefore faith is from hearing, etc., he draws the conclusion from what has been said, saying: therefore, since some do not believe unless they have heard, faith is from hearing. Psalm 17: at the hearing of the ear he has obeyed me. But it seems to be to the contrary that faith is a virtue divinely infused. Philippians 1: to you it is given, that you should believe in him. It must therefore be said that two things are required for faith: one of which is the inclination of the heart to believe, and this is not from hearing, but from the gift of grace; the other is the determination concerning what is to be believed, and this is from hearing. And therefore Cornelius, who had a heart inclined to believe, needed that Peter be sent to him, who might determine for him what was to be believed. Now from what he had said: how shall they hear without a preacher? and how shall they preach unless they be sent?, he concludes, but hearing, namely of believers, is through the word of preachers, which is the word of Christ, either because it is about Christ, 1 Corinthians 1: we preach Christ Jesus, or because they have it from Christ that they are sent, 1 Corinthians 11: for I have received of the Lord that which also I delivered unto you.”

“So then faith comes by hearing,.... That is, by preaching; for the word hearing is used in the same sense as in the preceding verse; and designs the report of the Gospel, or the preaching of the word, which is the means God makes use of, to convey faith into the hearts of his people; for preachers are ministers, or instruments, by whom others believe: and hearing by the word of God; or "of Christ", as some copies read, and so do the Vulgate Latin and Ethiopic versions; and intends either the holy Scriptures, which have God for their author, and Christ for the subject of them; and which furnish the men of God, or ministers of the Gospel, with proper materials to preach; and so hearing or preaching is by them, or else the command of God or Christ, which more properly signifies; and the sense is, that men preach the Gospel in obedience to the commandment of the everlasting God, and according to the orders, mission, and commission, warrant and authority, of the Lord Jesus Christ: and so these words are the conclusion, and sum of the whole; that as invocation is owing to faith, so faith to hearing, hearing to preaching, preaching to a mission; whence it follows, that it is the original will of God, to send forth his apostles and ministers, to preach the Gospel to the Gentiles, as well as to the Jews; that they hearing might believe, and believing call upon the Lord, and so be saved by him: it is a saying of the Jews, , "hearing depends upon the word" (e). (e) Zohar in Deut. fol. 110. 3.”

“So then faith cometh by hearing - Preaching the Gospel is the ordinary means of salvation; faith in Christ is the result of hearing the word, the doctrine of God preached. Preaching, God sends; if heard attentively, faith will be produced; and if they believe the report, the arm of the Lord will be revealed in their salvation.”
