Athanasius of Alexandria : For the Son of God indeed, being himself the Word, is Lord of all. But we once were subject from the first to the slavery of corruption and the curse of the law. Then by degrees fashioning for ourselves things that were not, we served, as says the blessed apostle, "them which by nature are no gods." Ignorant of the true God, we preferred things that were not to the truth. But afterwards, as the ancient people when oppressed in Egypt groaned, so when we too had the law "engrafted" in us, according to the unutterable sighings of the Spirit made our intercession, "O Lord our God, take possession of us"; then, as "he became a house of refuge" and a "God and defense," so also he became our Lord. Nor did he then begin to be, but we began to have him for our Lord. — Discourses Against the Arians 2.15.14 Augustine of Hippo : Therefore Christ will hand the kingdom over to God and the Father when through him the Father will be known by sight, for his kingdom consists of those in whom he now reigns through faith. In fact, in one sense Christ's kingdom means his divine power according to which every created thing is subject to him; and in another sense his kingdom means the church in respect to the faith that it has in him. In accord with this meaning is the prayer of him who says, "Possess us," for it is not the case that [Christ] himself does not possess all things. This is also the meaning of the following statement: "When you were the slaves of sin, you were free from righteousness." Therefore he will destroy every dominion and every authority and power, so that he who sees the Father through the Son will neither require nor be pleased with repose in his own or the power of any created thing. — QUESTION 69:4 Jerome : (Verse 13) Lord our God, we have been possessed by other lords without you; only in you do we remember your name. LXX: Lord our God, possess us: Lord; we know no other besides you, we invoke your name. Therefore, we seek mercy and peace, which must be given after all, because we have been possessed by other masters without you, namely idols or demons sitting on idols: and we ask for nothing else except that we may be worthy to remember your name after many errors. According to the Septuagint, they said: Lord God, possess us, they pray that they may become God's possession after peace is restored to them. Indeed, we read the same about Wisdom, which speaks according to the Hebrew in Proverbs: God possessed me at the beginning of His ways (Prov. VIII, 22), although some copies have the word 'possession' in a wrong way. Finally, it follows: Before all the hills, He has begotten me. For how could the generation of a creature be more suitable to possession? It is written in Deuteronomy: Did not this your father possess you, and make you, and create you (Deut. XXXII, 6)? And it must be noted that it does not say, the Lord or God possessed you, and made you, and created you; but rather father, in order to mitigate the severity of the power with the mercy of the name. And what follows: O Lord, we do not know another besides you, does not exclude the Son, but joins him to the Father, for he did not say 'We do not know another,' but 'We do not know another outside of you.' But when the Son says, 'I am in the Father, and the Father in me,' we do not know the Son outside of the Father, for we know him in the Father. Finally, we also name him by saying in the Lord's Prayer: 'Our Father, who art in heaven.' — Commentary on Isaiah
