**Basil - On the Spirit 9.23 **Hence comes foreknowledge of the future, understanding of mysteries, apprehension of what is hidden, distribution of good gifts, the heavenly citizenship, a place in the chorus of angels, joy without end, abiding in God, the being made like to God, and, the highest of all, the being made God.(PNF 8.16)
(see 1.2 …so far as possible with human nature, to be made like unto God. PNF 8.2)
Augustine - Letters 140.4 This is called adoption. For we were something before we were the sons of God, and we received the benefit of becoming what we were not, just as the one who adopted, before adoption, was not yet the son of the one who adopts him; still, he was one who could be adopted. From this begetting by grace we distinguish that son who, although He was the Son of God, came that He might become what He was not; nevertheless, He was something else, and this something was the Word of God, by whom all things were made, and the true light which enlightens every man, and God with God. Still, we were something, and this same something was much lower, that is sons of men. He therefore descended that we might ascend, and, while remaining in His own nature, became a sharer in our nature, so that we, while remaining in our own nature, might become sharers in His nature; but not in the same way, for He did not become worse by sharing in our nature, but we become better by sharing in His, (Fathers of the Church volume 11, pp. 64, 65.)
***Augustine - On the Psalms 50.2 **It is evident then, that He hath called men gods, that are deified of His Grace, not born of His Substance. For He doth justify, who is just through His own self, and not of another; and He doth deify who is God through Himself, not by the partaking of another. But He that justifieth doth Himself deify, in that by justifying He doth make sons of God. “For He that given them power to become sons of God”. If we have been made sons of God, we have also been made gods: but this is the effect of Grace adopting, not of nature generating. For only the Son of God, God, and one God with the Father, Our Lord and Saviour Jesus Christ, was in the beginning the Word, and the Word with God, the Word God. The rest that are made gods, are made by His own Grace, are not born of His Substance, that they should be the same a He, but that by favour they should come to Him, and be fellow-heirs with Christ. …“But we know,” he saith,“that when He shall have appeared, we shall be like Him, for we shall see Him as He is.” The Only Son is like him by birth, we like by seeing.(PNF 8.178).
**Jerome - Homily 14 **…That we are gods, not so by nature, but by grace. “But as many as received him he gave power of becoming sons of God.” I made man for that purpose, that from men they may become gods. “I said: You are gods, all of you sons of the most High.”(The Fathers of the Church 48.106)
John Chrysostom - Homilies on the Acts #32 …the man can become God, and a child of God. For we read, “I have said, Ye are gods, all of you are the children of the Most High.” (Ps. lxxxii. 6) And what is greater, the power to become both God and angel and child of God is put into his own hands.(PNF 11.205)
