John Chrysostom, on Acts 13:32

“And we declare unto you, that the promise which was made to our fathers,”

“"And we declare unto you glad tidings, how that the promise which was made unto the fathers, God hath fulfilled the same unto us their children, in that He hath raised up Jesus again; as it is also written in the second Psalm, Thou art My Son, this day have I begotten Thee." But, "He hath raised up Jesus again: This day," he says, "I have begotten thee." Aye, upon this the rest follows of course. Why did he not allege some text by which they would be persuaded that forgiveness of sins is by Him? Because the great point with them was to show, in the first place, that He was risen: this being acknowledged, the other was unquestionable. The reading "In the Second Psalm" is the best attested. If it is correct, we must suppose that what we now call the first psalm was considered introductory and that our second psalm was counted as the first. The expression "this day have I begotten thee" refers evidently to the resurrection of Christ. The resurrection is conceived as the solemn inauguration of Christ into his office as theocratic king represented under the figure of begetting.”
