"God also is truly perfect in all things, Himself equal and similar to Himself, as He is all light, and all mind, and all substance, and the fount of all good; but man receives advancement and increase towards God. For as God is always the same, so also man, when found in God, shall always go on towards God. For neither does God at any time cease to confer benefits upon, or to enrich man; nor does man ever cease from receiving the benefits, and being enriched by God." - St. Ireneaus, Against Heresies, 4.11.2
"we have not been made gods from the beginning, but at first merely men, then at length gods; although God has adopted this course out of His pure benevolence, that no one may impute to Him invidiousness or grudgingness. He declares, 'I have said, You are gods; and you are all sons of the Highest.'" - St. Ireneaus, Against Heresies, 4.38.4
"For it is thus that you will both controvert them in a legitimate manner, and will be prepared to receive the proofs brought forward against them, casting away their doctrines as filth by means of the celestial faith; but following the only true and steadfast Teacher, the Word of God, our Lord Jesus Christ, who did, through His transcendent love, become what we are, that He might bring us to be even what He is Himself." - St. Ireneaus, Against Heresies, 5.Preface
"You have, then, God's promise; you have His love: become partaker of His grace... And now the Word Himself clearly speaks to you, shaming your unbelief; yea, I say, the Word of God became man, that you may learn from man how man may become God. Is it not then monstrous, my friends, that while God is ceaselessly exhorting us to virtue, we should spurn His kindness and reject salvation?" - St. Clement of Alexandria, Exhortation to the Heathen, 1
"But that man with whom the Word dwells does not alter himself, does not get himself up: he has the form which is of the Word; he is made like to God; he is beautiful; he does not ornament himself: his is beauty, the true beauty, for it is God; and that man becomes God, since God so wills." - St. Clement of Alexandria, The Instructor, 3.1
"As, then, if a man should, similarly to those drugged by Circe, become a beast; so he, who has spurned the ecclesiastical tradition, and darted off to the opinions of heretical men, has ceased to be a man of God and to remain faithful to the Lord. But he who has returned from this deception, on hearing the Scriptures, and turned his life to the truth, is, as it were, from being a man made a god." - St. Clement of Alexandria, Stromata, 7.16
