And he put no difference. There was indeed some difference, because the Gentiles who were uncircumcised were suddenly admitted unto the covenant of eternal life; whereas the Jews were prepared by circumcision unto faith. But Peter's meaning is, that they were both chosen [1] together by God unto the hope of the same inheritance, and that they were extolled into the like degree of honor, that they might be the children of God and members of Christ, and, finally, the holy seed of Abraham, a priestly and princely generation. Whereupon it followeth, that they cannot without sacrilege be counted unclean, sithence God hath chosen them to be a peculiar people, and hath consecrated them to be holy vessels of his temple. For the wall of separation being pulled down, whereby the Gentiles and Jews were divided among themselves, he hath joined the Gentiles to the Jews, that they might grow together into one body, (Ephesians 2:14;) and that I may so say, he hath mixed circumcision and uncircumcision together, that as well those of the household as strangers may be one in Christ, and may make one Church; and that there may not be any longer either Jew or Grecian. Seeing that by faith he hath purified. This member is answerable to that former adjunct which he applieth to God; as if he should say, that God, who knoweth the hearts, did inwardly purge the Gentiles, when he vouchsafed to make them partakers of his adoption, that they might be endued with spiritual cleanness. But he addeth farther, that this purity did consist in faith. Therefore he teacheth, first, that the Gentiles have true holiness without ceremonies, which may suffice before God's judgment-seat. Secondly, he teacheth that this is attained unto by faith, and from it doth it flow. In like sort, Paul gathereth, that uncircumcision doth not hinder a man but that he may be counted holy and just before God, (Romans 4:10;) because circumcision did follow after righteousness in the person of Abraham, and by order of time it was latter, [posterior.] But here ariseth a question, whether that purity which the fathers had in times past were unlike to that which God gave now to the Gentiles? For it seemeth that Peter distinguisheth the Gentiles from the Jews by this mark, because, being content with the cleanness of the heart alone, they need no help of the law. I answer, that the one of them differ from the other, not in substance, but in form, [only.] For God had respect always unto the inward cleanness of the heart; and the ceremonies were given to the old [ancient] people only for this cause, that they might help their faith. So that cleanness, as touching figures and exercises, was only for a time, until the coming of Christ, which hath no place among us at this day; like as there remaineth from the very beginning of the world unto the end the same true worship of God, to wit, the spiritual worship; yet is there great difference in the visible form. Now, we see that the fathers did not obtain righteousness by ceremonies, neither were they therefore pure before God, but by the cleanness of the heart. For the ceremonies of themselves were of no importance to justify them; but they were only helps, which did accidentally (that I may so term it) purge them; yet so that the fathers and we had the same truth. Now, when Christ came, all that which was accidental did vanish away; and, therefore, seeing the shadows be driven away, there remaineth the bare and plain pureness of the heart. Thus is that objection easily answered which the Jews think cannot possibly be answered. Circumcision is called the eternal covenant, or of the world, (Genesis 17:13;) therefore, say they, it was not to be abolished. If any man shall say that this is not referred unto the visible sign, but rather unto the thing figured, it shall be well answered; but there is another answer besides this. Seeing that the kingdom of Christ was a certain renewing of the world, there shall no inconvenience follow if he made an end of [2] all the shadows of the law, forasmuch as the perpetuity of the law is grounded in Christ. I come now unto the second member, where Peter placeth the cleanness [purity] of the Gentiles in faith. Why doth not he say, In perfection of virtues, or holiness of life, save only because men have righteousness from another, and not from themselves? For, if men, by living well and justly, should purchase righteousness, or if they should be clean before God by nature, this sentence of Peter should fall to the ground. Therefore, the Spirit doth in these words plainly pronounce that all mankind is polluted, and with filthiness defiled; secondly, that their blots can by no other means be wiped away than by the grace of Christ. For, seeing that faith is the remedy whereby the Lord doth freely help us, it is set as well against the common nature of all men, as against every man's own merits. When I say that all mankind is polluted, my meaning is, that we bring nothing from our mother's womb but mere filthiness, and that there is no righteousness in our nature which can reconcile us to God. Man's soul was indeed endued with singular gifts at the first; but all parts thereof are so corrupt with sin, that there remaineth in it no drop of pureness any longer; therefore we must seek for cleanness without ourselves. For if any man allege that it may be recovered by merits of works, there is nothing more absurd than to imagine that wicked and coward nature can deserve anything. Therefore, it resteth that men seek elsewhere for that which they shall never be able to find within themselves. And surely it is the office of faith to translate that unto us which is proper to Christ, and to make it ours by free participation. So that there is a mutual relation between faith and the grace of Christ. For faith doth not make us clean, as a virtue or quality poured into our souls; but because it receiveth that cleanness which is offered in Christ. We must also note the phrase, that God purifieth the hearts; whereby Luke doth both make God the author of faith, and he teacheth also that cleanness is his benefit. To make short, he signifieth unto us, that that is given to men by the grace of God which they cannot give to themselves. But forasmuch as we said that faith taketh that of Christ which it transpoureth [transferreth] into us; we must now see how the grace of Christ doth make us clean, that we may please God. And there is a double manner of purging, because Christ doth offer and present us clean and just in the sight of his Father, by putting away our sins daily, which he hath once purged by his blood; secondly, because, by mortifying the lusts of the flesh by his Spirit, he reformeth us unto holiness of life. I do willingly comprehend both kinds of purging under these words; because Luke doth not touch one kind of purging only, but he teacheth that the whole perfection thereof consisteth without the ceremonies of the law.

1 - "Utrosque pariter allectos esse," that both were in like manner allured.

2 - "Nihil esse absurdi si finem... imposuerit," there is no absurdity in his having put an end to.

And put no difference - Though they had not been circumcised, and though they did not conform to the Law of Moses. Thus, God showed that the observance of these rites was not necessary in order to the true conversion of people, and to acceptance with him. He did not give us, who are Jews, any advantage over them, but justified and purified all in the same manner.
Purifying their hearts - Thus, giving the best evidence that he had renewed them, and admitted them to favor with him.
By faith - By believing on the Lord Jesus Christ. This demonstrated that the plan on which God was now about to show favor to people was not by external rites and ceremonies, but by a scheme which required faith as the only condition of acceptance. It is further implied here that there is no true faith which does not purify the heart.

Put no difference between us and them - Giving them the Holy Spirit, though uncircumcised, just as he had given it to us who were circumcised: an evident proof that, in the judgment of God, circumcision was no preparation to receive the Gospel of Christ. And as the purification of the heart by the Holy Spirit was the grand object of the religion of God, and that alone by which the soul could be prepared for a blessed immortality, and the Gentiles had received that without circumcision, consequently, the shadow could not be considered of any worth, now the substance was communicated.

And put no (d) difference between us and them, purifying their hearts (e) by faith.
(d) He put no difference between us and them, with regard to the benefit of his free favour.
(e) Christ proclaims those blessed who are pure of heart: and here we are plainly taught that men are made pure of heart by faith.

And put no difference between us and them,.... Neither in the extraordinary gifts, nor special grace, of the Spirit; giving them the same graces of faith, hope, and love, admitting to the same privileges and immunities of the house of God, and giving them a right and title to the same inheritance of the saints in light, though the one were circumcised, and the other were not. God puts no difference as to matters of religion under the Gospel dispensation between Jews and Gentiles, neither on account of Abraham's seed, or of circumcision, or of the ceremonial law, or of national adoption; nor would he have any made with respect to conversation, civil or religious; all which Peter knew full well: nor has he made any difference in his eternal choice of persons to eternal salvation, on any of the above accounts, having ordained Gentiles to eternal life as Jews, who in consequence of it believe in Christ; nor in redemption, Christ having redeemed by his blood men out of every kindred, tongue, people, and nation; nor in the effectual calling, for they that were called in the first times of the Gospel, were not of the Jews only, but of the Gentiles also, to whom the Gospel was alike sent, and made effectual to saving purposes: these shared in the same blessings of pardon, justification, and adoption; their sins were forgiven through the same blood, their persons were justified by the same righteousness, and they were taken into the same family, and were no more strangers and foreigners, but fellow citizens of the saints, and of the household of God; having the same access to God, being built on the same foundation, enjoying the same privileges, and having the same hope of eternal glory.
Purifying their hearts by faith; which was done by implanting faith in them, and leading that faith to the blood of Christ, which cleanses from all sin, original and actual, with which men are defiled; for faith has not this efficacy in itself, but as it has to do with the blood of Jesus: and this spiritual purification being what answered to circumcision, made that unnecessary; for this is the circumcision of the heart, of which the other was only typical. The hearts of men are filthy, and need purifying; they are originally polluted with sin; this is the case of all men; and this defilement reaches to all the members of the body, and the faculties of the soul; and especially the heart is the seat of this impurity, which God only can cleanse: he promises to do it, and does do it; and he only can do it, men cannot; for though, they are exhorted to it, in order to make them sensible of their pollution, and their need of cleansing, that they may apply where it is to be had, yet it is not in their power to effect it; to make a clean heart is a creation work, which is peculiar to God: the heart cannot be purified, neither by ceremonial ablutions, nor by works of moral righteousness, nor by humiliations and tears, nor by submission to Gospel ordinances, as water baptism, but only by the grace of God, and the blood of Christ; which the Spirit of God sprinkles upon the heart, and which faith looks to and deals with, and so it is freed from an evil conscience; and this blessing the believing Gentiles enjoyed in common with the believing Jews.

put no difference between us and them: purifying their hearts by faith--"Purification" here refers to "sprinkling (of the conscience by the blood of Jesus) from dead works to serve the living God." (See on 1-Corinthians 6:11). How rich is this brief description of the inward revolution wrought upon the genuine disciples of the Lord Jesus!

Purifying - This word is repeated from Acts 10:15; their hearts - The heart is the proper seat of purity; by faith - Without concerning themselves with the Mosaic law.
