Acts 2:39

17. For whereas in the Gospels, and in the epistles of the apostles, the name of Christ is alleged for the remission of sins; it is not in such a way as that the Son alone, without the Father, or against the Father, can be of advantage to anybody; but that it might be shown to the Jews, who boasted as to their having the Father, that the Father would profit them nothing, unless they believed on the Son whom He had sent. For they who know God the Father the Creator, ought also to know Christ the Son, lest they should flatter and applaud themselves about the Father alone, without the acknowledgment of His Son, who also said, “No man cometh to the Father but by me.” But He, the same, sets forth, that it is the knowledge of the two which saves, when He says, “And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom thou hast sent.” Since, therefore, from …

25. If at the least they once had in this world wherewithal they might easily without handiwork sustain this life, which property, when they were converted unto God, they disparted to the needy, then must we both believe their infirmity, and bear with it. For usually such persons, having been, not better brought up, as many think, but what is the truth, more languidly brought up, are not able to bear the labor of bodily works. Such peradventure were many in Jerusalem. For it is also written, that they sold their houses and lands, and laid the prices of them at the Apostles’ feet, that distribution might be made to every one as he had need. …

Do you see what a great thing gentleness is? More than any vehemence, it pricks our hearts, inflicts a keener wound. For as in the case of bodies which have become callous, the man that strikes upon them does not affect the sense so powerfully, but if he first mollify them and make them tender, then he pierces them effectually; so in this instance also, it is necessary first to mollify. But that which softens, is not wrath, not vehement accusation, not personal abuse; it is gentleness. The former indeed rather aggravate the callousness, this last alone removes it. If then you are desirous to reprove any delinquent, approach him with all possible mildness. …

[“Now when they heard this,” etc. “Then Peter said unto them,” etc.] (Recapitulation, v. 37 .) What had been said was not enough. For those sayings indeed were sufficient to bring them to faith; but these are to show what things the believer behooves to do. And he said not, In the Cross, but, “In the name of Jesus Christ let every one of you be baptized.” ( v. 38 .) And he does not put them continually in mind of the Cross, that he may not seem to reproach them, but he says simply, “Repent:” and why? That we may be punished? No: “And let each of you be baptized in the name of Jesus Christ, for the remission of sins.” And yet quite other is the law; of this world’s tribunals: but in the case of the Gospel proclamation ( κηρύγματος ); when the delinquent has confessed, then is he saved! Observe how Peter does not instantly hurry over this, but he specifies also the conditions, and adds, “Y …

And that we do not contend for this on our own conviction but retain it on Apostolic authority, we prove by a sufficiently apt example, following the blessed Apostle Peter, who, on the very day on which the promised coming of the Holy Ghost filled up the number of those that believed, dedicated to God in the baptismal font three thousand of the people who had been converted by his preaching. The Holy Scripture, which contains the Acts of Apostles, teaches this in its faithful narrative, saying, “Now when they heard this they were pricked in the heart, and said unto Peter and to the rest of the Apostles, what shall we do, brethren? But Peter said unto them, Repent ye and be baptized every one of you in the name of Jesus Christ, unto the remission of your sins, and ye shall receive the gift of the Holy Ghost. …

In fact, the case of the Crucified is so different from that of His crucifiers that what Christ undertook could not be reversed, while what they did could be wiped out. For He Who came to save sinners did not refuse mercy even to His murderers, but changed the evil of the wicked into the goodness of the believing, that God’s grace might be the more wonderful, being mercifully put in force, not according to men’s merits, but according to the multitude of the riches of God’s wisdom and knowledge, seeing that they also who had shed the Saviour’s blood were received into the baptismal flood. …
