Acts 2:35

And that God the Father of all would bring Christ to heaven after He had raised Him from the dead, and would keep Him there until He has subdued His enemies the devils, and until the number of those who are foreknown by Him as good and virtuous is complete, on whose account He has still delayed the consummation-hear what was said by the prophet David. These are his words: "The Lord said unto My Lord, Sit Thou at My right hand, until I make Thine enemies Thy footstool. The Lord shall send to Thee the rod of power out of Jerusalem; and rule Thou in the midst of Thine enemies. With Thee is the government in the day of Thy power, in the beauties of Thy saints: from the womb of morning have I begotten Thee." That which he says, "He shall send to Thee the rod of power out of Jerusalem," is predictive of the mighty, word, which His apostles, going forth from Jerusalem, preached everywhere; and though death is decreed against those who teach or at all confess the name of Christ, we everywhere both embrace and teach it. And if you also read these words in a hostile spirit, ye can do no more, as I said before, than kill us; which indeed does no harm to us, but to you and all who unjustly hate us, and do not repent, brings eternal punishment by fire.

Henceforth after the mention of His giving the Spirit, he confidently speaks also of His ascension into heaven; and not only so, but again adducing the witness, and reminding them of that Person concerning Whom Christ once spake. "For not David," says he "ascended into the heavens." Here he no longer speaks in lowly phrase, having the confidence which results from the things said nor does he say, "Be it permitted me to speak," or the like: "But he saith himself; The Lord said unto my Lord, Sit Thou on My right hand, until I make Thine enemies Thy footstool." Now if He be David's Lord, much more shall they not disdain Him. "Sit thou on My right hand;" he has set the whole matter here; "until I make Thine enemies Thy footstool:" here also he has brought upon them a great terror, just as in the beginning he showed what He does to His friends, what to his enemies. And again, as to the act of subjugation, not to provoke unbelief, he ascribes it to the Father.

The words "Sit on my right hand" he speaks as to man, for they are not spoken to him that sits ever on the throne of glory, God the Word after his ascension from earth, but they are said to him who has now been exalted to the heavenly glory as man, as the apostles say, "for David is not ascended into the heavens, but he himself says that the Lord said to my Lord 'Sit on my right hand.' " The order is human, giving a beginning to the sitting; but it is a divine dignity to sit together with God "to whom thousand thousands minister and before whom ten thousand times ten thousand stand."

And he sets before them a fear by the phrase, "until I make your enemies." And so that they may not disbelieve, he assigns the submission to the Father.

"Until I make your enemies your footstool." This is what Peter elsewhere said about the Lord: "Whom heaven must receive until the times of restoration of all things" (Acts III). For then, when all times of refreshing come from the presence of the Lord, He will send Jesus Christ, who was preached to us from royal thrones, to judge the living and the dead (Wisdom XVIII).

For David did not ascend into the heavens, but he himself says: The Lord said to my Lord, sit at my right hand. Certain codices have 'The Lord says,' but Greek exemplars in both this book and the Psalter have 'The Lord said.' Most clearly, blessed Peter explains through this psalm how to understand what he previously assumed from another psalm, that the Lord swore to David to raise Christ from the fruit of his loins and to set him on his throne, namely, because this throne of the kingdom is not to be understood in earthly Jerusalem where David reigned, but at the right hand of His majesty in the heavens. Here he evidently asserts both natures of our one Redeemer from the prophetic scriptures: the human, from the fruit of David's loins through the virgin, and the divine because ascending into heaven, the man was received at the right hand of the Father. In this truly, He is the son of David, in that He is the Lord of David, for which reason he congruously added:

By David's words "until I make Your enemies a footstool for Your feet," Peter instilled fear in them as a means of conquering them. And so as not to undermine their faith in him, he ascribes everything to the Father. After having spoken of great matters, he brings his discourse back again to the deeds of Jesus' humility. And who these enemies are, the apostle explains, crying out: "The last enemy that shall be destroyed is death, for He hath put all things under His feet" (1 Cor. 15:26–27).
