And take unto you the helmet of salvation, and the sword of the Spirit (which is the word of God).

“Who will ply the sword without practising the contraries to lenity and justice; that is, guile, and asperity, and injustice, proper (of course) to the business of battles? See we, then, whether that which has another action be not another sword,-that is, the Divine word of God, doubly sharpened with the two Testaments of the ancient law and the new law; sharpened by the equity of its own wisdom; rendering to each one according to his own action.”

“"And take the helmet," he continues, "of salvation," that is, of your salvation. For he is casing them in armor. And therefore he adds further, "and take the helmet of salvation"; that is to say, finally by this shall ye be able to be in security. To receive the helmet of salvation is to escape the peril. For as the helmet covers the head perfectly in every part, and suffers it not to sustain any injury, but preserves it, so also does faith supply alike the place of a shield, and of a helmet to preserve us. For if we quench his darts, quickly shall we receive also those saving thoughts that suffer not our governing principle to sustain any harm; for if these, the thoughts that are adverse to our salvation, are quenched, those which are not so, but which contribute to our salvation, and inspire us with good hopes, will be generated within us, and will rest upon our governing principle, as a helmet does upon the head. "And the sword of the Spirit, which is the word of God." He either means the Spirit, or else, "the spiritual sword": for by this all things are severed, by this all things are cleft asunder, by this we cut off even the serpent's head. And not only this, but we shall take also "the sword of the Spirit," and thus not only ward off his missiles, but smite the devil himself. For a soul that does not despair of herself, and is proof against those fiery darts, will stand with all intrepidity to face the enemy, and will cleave open his breastplate with this very sword with which Paul also burst through it, and "brought into captivity his devices" (2 Cor. x. 5); he will cut off and behead the serpent. "Which is the word of God." By the "word of God" in this place, he means on the one hand the ordinance of God, or the word of command; or on the other that it is in the Name of Christ. For if we keep his commandments, by these we shall kill and slay the dragon himself, "the crooked serpent." (Isa. xxvii. 1.) And as he said, "Ye shall be able to quench the fiery darts of the evil one"; that he might not puff them up, he shows them, that above all things they stand in need of God; for what does he say?”

“Above, the Apostle explained what was said about the snares of the Devil; here he admonishes us about taking up armor. And concerning this he does two things. First he concludes from the foregoing the necessity of the armor; second, he describes the diversity of the arms, there: "Stand therefore," etc. He says therefore: you have enemies who are evil, most wicked and powerful, and fighting for an arduous cause, because for heavenly things; therefore "take unto you the armor of God," that is, arm yourselves with spiritual arms. 2 Corinthians 10:4: "The weapons of our warfare are not carnal, but mighty to God unto the destruction of fortifications," etc. And this, "that you may be able to resist." 1 Peter 5:9: "Whom resist, strong in faith," etc. James 4:7: "Resist the devil, and he will flee from you." For the more one yields to him, the more he pursues. "In the evil day," and this on account of the evils which happen in the day. Above, 5:16: "Redeeming the time, because the days are evil." Ecclesiastes 7:15: "Beware of the evil day," etc. Likewise, take it up not only for resisting, but also for making progress, and "in all things stand perfect," that is, stand immovably both in adversity and in prosperity. James 1:4: "that you may be perfect, wanting in nothing." On this, 1 Peter 1:13: "perfect, hope in that grace which is offered to you," etc. But should all be perfect? I respond: perfection is threefold. One is a perfection of sufficiency, which a man has insofar as he has what is necessary for him unto salvation, as in that saying: "You shall love the Lord your God with your whole heart" — as if to say: let there be nothing in your heart that is against God. And this belongs to the necessity of salvation. James 1:4: "that you may be perfect and entire, failing in nothing," etc. The other is the perfection of total abundance, which is the perfection of the homeland, which is consummated glory, in this — that the perfect one wholly cling to God. Matthew 22:30: "In the resurrection they shall neither marry, nor be married, but shall be as the angels of God in heaven." And of this the Apostle was speaking, Philippians 3:12: "Not as though I had already attained, or were already perfect." And a little after: "Brethren, I do not count myself to have apprehended." The other is a middle perfection, namely of counsel, by which a man strives to draw himself away from these things and go toward those. Then when he says "Stand therefore," etc., he describes the diversity of the arms. Now there is a threefold kind of spiritual arms, on the likeness of bodily ones: of which some are like a garment, for covering; some indeed for protecting; and some for attacking. Now three things are necessary for the garment. First, that it be girded; and as to this he says, "Stand therefore, having your loins girt about," etc. But a man puts on his garment before he girds himself. The Apostle, however, takes these things according to the order of spiritual armor. Now in spiritual warfare it is first necessary to restrain the concupiscences of the flesh, just as the nearest enemy must be conquered first; and this is done through the restraining of the loins, in which lust flourishes, which is done through temperance, which is contrary to gluttony and lust. Luke 12:35: "Let your loins be girt," etc. Job 38:3: "Gird up your loins like a man," etc. But "in truth," that is, in rectitude of intention, and not in pretense. Another text has: "in charity." 1 Corinthians, the last chapter: "Let all your things be done in charity." Second, he admonishes us to conquer the cupidities for things. Now a twofold armor is found against these, namely justice, and renunciation of temporal things. And therefore first he commands that we not usurp them unjustly, which justice accomplishes. And therefore he says, "having put on the breastplate of justice," namely, on account of which a man abstains from things belonging to another. Now justice is called a breastplate because, just as a breastplate covers the members, so justice covers all the virtues. Wisdom 5:19: "He shall put on justice as a breastplate, and shall take true judgment instead of a helmet." Second, he commands that we lay aside superfluous care for temporal things, because while we attend to these too much, we do not have our feet ready for announcing divine business and mysteries. And on account of this he says, "and your feet shod," that is, let your affections be disposed — supply: "in the preparation of the Gospel of peace." As a sign of this the Lord sent out the apostles, Mark 6:9, shod with sandals, which have soles underneath — by which is signified the elevation of the mind from earthly things — and which are open above — by which is signified readiness for divine wisdom. Now he says "of peace," because through the Gospel peace is announced to us. Matthew 10:12: "Into whatsoever house you enter, say: Peace be to this house." Likewise, second, there are arms for protecting. Now two things in us are to be protected, which are the principles of life, namely the breast, in which is the heart, and the head, in which is the brain. Now for the breast there is the shield. And therefore he says, "in all things taking the shield of faith," because just as the shield is placed beneath all the other arms, so faith is beneath all the other virtues. For the other arms are of the moral virtues — namely, of temperance, that is, the girding of the loins, and of justice, that is, the putting on of the breastplate — but this kind of arms, namely the shield, is of a theological virtue, namely faith; because just as by the shield darts are repelled, so by faith all contrary things are repelled and victory is had. Hebrews 11:33: "The saints by faith conquered kingdoms," just as by the moral virtues we conquer earthly powers. And therefore he says, "in which you may be able to extinguish all the fiery darts of the most wicked one," namely the Devil, whose darts are certain incitements sent through evil angels. They are fiery, because they burn with wicked desires. Psalm 57:9: "Fire fell upon," etc. Now these are extinguished through faith, which extinguishes present and transitory temptations through spiritual and eternal goods, which sacred Scripture promises. Hence the Lord, when the Devil was tempting him, brought forward and set against him the authorities of sacred Scripture. And thus we ought to do: if he tempts concerning gluttony, according to that saying, Deuteronomy 8:3: "Man does not live by bread alone"; or that: "The kingdom of God is not food and drink." If concerning lust: "You shall not commit adultery." If concerning theft: "You shall not steal"; and so with the others. Now it is called "the shield of faith," because just as the shield protects the whole breast, so faith ought to be in the breast. Now hope is called a helmet, because just as the helmet is on the head, so the head of the moral virtues is the end; and hope concerns this, namely the end. And therefore it is said, "and take unto you the helmet of salvation." Likewise, third, there are arms for attacking, because it is not enough to defend oneself, but it is also necessary to attack the adversary. Now just as this is done bodily through a material sword, so it is done spiritually through the word of God, which is the sword of the Holy Spirit. And on account of this he says, "and the sword of the Spirit, which is the word of God" — namely, take it up. Hebrews 4:12: "The word of God is living and effective, and more penetrating than any two-edged sword, reaching even to the division of soul and spirit." And preaching is called "the sword of the Spirit," because it does not penetrate even to the spirit, unless it is led by the Holy Spirit. Matthew 10:20: "For it is not you who speak, but the Spirit of your Father who speaks in you." Thus, then, we have arms by which we are defended from carnal enemies, namely from gluttony and lust, which is done through temperance, there: "Stand therefore, having your loins girt about," etc. Likewise, we have arms by which we conquer earthly cupidities, namely the arms of justice, which make us abstain from unlawful things, there: "having put on the breastplate of justice." And the arms of purity of affection, or poverty, which draws us back even from lawful things, there: "your feet shod," etc. Likewise, we have arms by which we are protected from errors, namely the arms of faith, there: "in all things taking the shield of faith," and also from the enemies of the human race, there: "in which," namely by the shield of faith, "you may be able to extinguish all the fiery darts of the most wicked one." Likewise, we have arms by which we are confirmed in spiritual goods, namely the arms of hope, there: "and take unto you the helmet of salvation." The helmet is placed on the head; thus hope is placed upon the end. Now the head of the moral virtues is the end itself, concerning which is hope. Hence, to take up the helmet of salvation is nothing other than to have hope concerning the last end. Likewise, we have arms for attacking the demons themselves, namely the sword of the Spirit, which is the word of God — which is done frequently in sermons, in which the word of God, penetrating the hearts of sinners, expels the mass of sins and of demons.”

“And take the helmet of salvation,.... Meaning either Christ himself, the Saviour; and so the Arabic version renders it, "the helmet of the Saviour": or the salvation itself, which he is the author of, and a well grounded hope of it; see Th1 5:8; the allusion is to Isa 59:17; and such an hope of salvation by Christ is a defence of the head against false doctrines; for the helmet is a piece of armour for the head; and it is an erecter of the head in times of difficulty, affliction, and distress; and it covers the head in the day of battle, when engaged with Satan, the enemy of souls: and the sword of the Spirit, which is the word of God; the word of God is compared to a "sword", for its two edges, the law and Gospel; the one convicts of sin, and cuts to the heart for it, and the other cuts down all the goodliness of man; and the Scriptures in general are a sharp sword, in convincing of sin, reproving for it, and threatening with wrath and ruin, in refuting error and heresy, and repelling Satan's temptations, and will be used in the destruction of antichrist: and this word may be called "the sword of the Spirit", because it is not carnal, but of a spiritual nature; and is used by the spiritual man; and because the Holy Spirit, as the Ethiopic version here expresses it, is the author of it; and which he furnishes the saints with, and teaches them how to make use of, and makes it powerful and effectual. So the Jews say (t), the words of the law are like to a sword, and speak of "the sword of the law" (u). (t) Targum in Cant. 3. 8. (u) Bereshit Rabba, sect. 21. fol. 19. 1.”

“Take the helmet of salvation - Or, as it is expressed, Th1 5:8, And for a helmet, the hope of salvation. It has already been observed, in the description of the Grecian armor, that on the crest and other parts of the helmet were a great variety of emblematical figures, and that it is very likely the apostle refers to helmets which had on them an emblematical representation of hope; viz. that the person should be safe who wore it, that he should be prosperous in all his engagements, and ever escape safe from battle. So the hope of conquering every adversary and surmounting every difficulty, through the blood of the Lamb, is as a helmet that protects the head; an impenetrable one, that the blow of the battle-axe cannot cleave. The hope of continual safety and protection, built on the promises of God, to which the upright follower of Christ feels he has a Divine right, protects the understanding from being darkened, and the judgment from being confused by any temptations of Satan, or subtle arguments of the sophistical ungodly. He who carries Christ in his heart cannot be cheated out of the hope of his heaven, The sword of the Spirit - See what is said before on ξιφος and μαχαιρα, in the account of the Greek armor (Eph 6:13 (note)). The sword of which St. Paul speaks is, as he explains it, the word of God; that is, the revelation which God has given of himself, or what we call the Holy Scriptures. This is called the sword of the Spirit, because it comes from the Holy Spirit, and receives its fulfillment in the soul through the operation of the Holy Spirit. An ability to quote this on proper occasions, and especially in times of temptation and trial, has a wonderful tendency to cut in pieces the snares of the adversary. In God's word a genuine Christian may have unlimited confidence, and to every purpose to which it is applicable it may be brought with the greatest effect. The shield, faith, and the sword - the word of God, or faith in God's unchangeable word, are the principal armor of the soul. He in whom the word of God dwells richly, and who has that faith by which he knows that he has redemption, even the forgiveness of sins, need not fear the power of any adversary. He stands fast in the liberty wherewith Christ hath made him free. Some suppose that του Πνευματος, of the Spirit, should be understood of our own spirit or soul; the word of God being the proper sword of the soul, or that offensive weapon the only one which the soul uses. But though it is true that every Christian soul has this for its sword, yet the first meaning is the most likely.”

“take--a different Greek word from that in Eph 6:13, Eph 6:16; translate, therefore, "receive," "accept," namely, the helmet offered by the Lord, namely, "salvation" appropriated, as Th1 5:8, "Helmet, the hope of salvation"; not an uncertain hope, but one that brings with it no shame of disappointment (Rom 5:5). It is subjoined to the shield of faith, as being its inseparable accompaniment (compare Rom 5:1, Rom 5:5). The head of the soldier was among the principal parts to be defended, as on it the deadliest strokes might fall, and it is the head that commands the whole body. The head is the seat of the mind, which, when it has laid hold of the sure Gospel "hope" of eternal life, will not receive false doctrine, or give way to Satan's temptations to despair. God, by this hope, "lifts up the head" (Psa 3:3; Luk 21:28). sword of the Spirit--that is, furnished by the Spirit, who inspired the writers of the word of God (Pe2 1:21). Again the Trinity is implied: the Spirit here; and Christ in "salvation" and God the Father, Eph 6:13 (compare Heb 4:12; Rev 1:16; Rev 2:12). The two-edged sword, cutting both ways (Psa 45:3, Psa 45:5), striking some with conviction and conversion, and others with condemnation (Isa 11:4; Rev 19:15), is in the mouth of Christ (Isa 49:2), in the hand of His saints (Psa 149:6). Christ's use of this sword in the temptation is our pattern as to how we are to wield it against Satan (Mat 4:4, Mat 4:7, Mat 4:10). There is no armor specified for the back, but only for the front of the body; implying that we must never turn our back to the foe (Luk 9:62); our only safety is in resisting ceaselessly (Mat 4:11; Jam 4:7).”
