(38) Repent, and be baptized every one of you in the name of Jesus Christ.--The work of the Apostles is, in one sense, a continuation, in another a development, of that of the Baptist. There is the same indispensable condition of "repentance"--i.e. a change of heart and will--the same outward rite as the symbol of purification, the same promise of forgiveness which that change involves. But the baptism is now, as it had not been before, in the name of Jesus Christ, and it is connected more directly with the gift of the Holy Spirit. The question presents itself, Why is the baptism here, and elsewhere in the Acts (Acts 10:48; Acts 19:5), "in the name of Jesus Christ," while in Matthew 28:19, the Apostles are commanded to baptize in the name of the Father, the Son, and the Holy Spirit? Various explanations have been given. It has been said that baptism in the Name of any one of the Persons of the Trinity, involves the Name of the other Two. It has even been assumed that St. Luke meant the fuller formula when he used the shorter one. But a more satisfactory solution is, perhaps, found in seeing in the words of Matthew 28:19 (see Note there) the formula for the baptism of those who, as Gentiles. had been "without God in the world, not knowing the Father;" while for converts from Judaism, or those who had before been proselytes to Judaism, it was enough that there should be the distinctive profession of their faith in Jesus as the Christ, the Son of God, added on to their previous belief in the Father and the Holy Spirit. In proportion as the main work of the Church of Christ lay among the Gentiles, it was natural that the fuller form should become dominant, and finally be used exclusively. It is interesting here, also, to compare the speech of St. Peter with the stress laid on baptism in his Epistle (1Peter 3:21).

Ye shall receive the gift of the Holy Ghost.--The word for "gift" (dorea) is generic, and differs from the more specific "gift" (charisma) of 1Corinthians 12:4; 1Corinthians 12:9; 1Corinthians 12:28. The Apostle does not necessarily promise startling and marvellous powers, but in some way they should all feel that a new Spirit was working in them, and that that Spirit was from God.

Verse 38. - And for then, A.V.; said (in italics) for said, A.V. and T.R.; repent ye for repent, A.V.; unto for for, A.V.; your sins for sins, A.V. Repent, etc. We have in this short verse the summary of Christian doctrine as regards man and God. Repentance and faith on the part of man; forgiveness of sins, or justification, and the gift of the Holy Ghost, or sanctification, on the part of God. And both these are expressed in the sacrament of baptism, which as it were ties the act of man to the promise of God. For the sacrament expresses man's faith and repentance on one side, and God's forgiveness and gift on the other.

2:37-41 From the first delivery of that Divine message, it appeared that there was Divine power going with it; and thousands were brought to the obedience of faith. But neither Peter's words, nor the miracle they witnessed, could have produced such effects, had not the Holy Spirit been given. Sinners, when their eyes are opened, cannot but be pricked to the heart for sin, cannot but feel an inward uneasiness. The apostle exhorted them to repent of their sins, and openly to avow their belief in Jesus as the Messiah, by being baptized in his name. Thus professing their faith in Him, they would receive remission of their sins, and partake of the gifts and graces of the Holy Spirit. To separate from wicked people, is the only way to save ourselves from them. Those who repent of their sins, and give up themselves to Jesus Christ, must prove their sincerity by breaking off from the wicked. We must save ourselves from them; which denotes avoiding them with dread and holy fear. By God's grace three thousand persons accepted the gospel invitation. There can be no doubt that the gift of the Holy Ghost, which they all received, and from which no true believer has ever been shut out, was that Spirit of adoption, that converting, guiding, sanctifying grace, which is bestowed upon all the members of the family of our heavenly Father. Repentance and remission of sins are still preached to the chief of sinners, in the Redeemer's name; still the Holy Spirit seals the blessing on the believer's heart; still the encouraging promises are to us and our children; and still the blessings are offered to all that are afar off.Then Peter said unto them,.... Being the mouth of the apostles, and being ready to give advice, and speak a word of comfort to their distressed minds:

repent: change your minds, entertain other thoughts, and a different opinion of Jesus of Nazareth, than you have done; consider him, and believe in him, as the true Messiah and Saviour of the world; look upon him, not any more as an impostor, and a blasphemer, but as sent of God, and the only Redeemer of Israel; change your voice and way of speaking of him, and your conduct towards his disciples and followers; a change of mind will produce a change of actions in life and conversation: bring forth fruits meet for repentance; and make an open and hearty profession of repentance for this your sin. And this the apostle said, to distinguish between a legal and an evangelical repentance; the former is expressed in their being pricked to the heart, on which they were not to depend; the latter he was desirous they might have, and show forth; which springs from the love of God, is attended with views, or at least hopes of pardoning grace and mercy, and with faith in Christ Jesus: it lies in a true sight and sense of sin, under the illuminations and convictions of the Spirit of God; in a sorrow for it, after a godly sort, and because it is committed against a God of love, grace, and mercy, and it shows itself in loathing sin, and in shame for it, in an ingenuous acknowledgement of it, and in forsaking it: and this is moreover urged, to show the necessity of it, as to salvation, for such that God would not have perish, he will have come to repentance; so to their admission to the ordinance of baptism, to which repentance is a pre-requisite; and to which the apostle next advises:

and be baptized everyone of you; that repents and believes; that is, in water, in which John administered the ordinance of baptism; in which Christ himself was baptized, and in which the apostles of Christ administered it; in this Philip baptized the eunuch; and in this were the persons baptized that were converted in Cornelius's house; and it is distinguished from the baptism of the Spirit, or with fire, the extraordinary gifts of the Spirit mentioned in the last clause of this verse; and which ordinance of water baptism was administered by immersion, as the places, Jordan and Aenon, where John performed it, and the instances of it particularly in Christ, and in the eunuch, and the end of it, which is to represent the death, burial, and resurrection of Christ, as well as the primary signification of the word, show. And this is to be done,

in the name of Jesus Christ; not to the exclusion of the Father, and of the Spirit, in whose name also this ordinance is to be administered, Matthew 28:19 but the name of Jesus Christ is particularly mentioned, because of these Jews, who had before rejected and denied him as the Messiah; but now, upon their repentance and faith, they are to be baptized in his name, by his authority, according to his command; professing their faith in him, devoting themselves to him, and calling on his name. The end for which this was to be submitted to, is,

for the remission of sins; not that forgiveness of sin could be procured either by repentance, or by baptism; for this is only obtained by the blood of Christ; but the apostle advises these awakened, sensible, repenting, and believing souls, to submit to baptism, that by it their faith might be led to Christ, who suffered and died for their sins, who left them buried in his grave, and who rose again for their justification from them; all which is, in a most lively manner, represented in the ordinance of baptism by immersion: the encouragement to it follows,

and ye shall receive the gift of the Holy Ghost: not the grace of the Spirit, as a regenerator and sanctifier; for that they had already; and is necessary, as previous to baptism; unless it should mean confirmation of that grace, and stability in it, as it appears from Acts 2:42 they afterwards had; but rather the extraordinary gifts of the Spirit, particularly the gift of speaking with tongues, which Christ had received from the Father, and had now shed on his apostles; see Acts 19:5.
