Genesis 3:5 (NRSV) — Theosis

Origen

Thou shalt resemble Him . . . having made thee even God to his glory.

See what love the Father has given us, that we should be called children of God, and that is what we are. The reason the world does not know us is that it did not know him. Beloved, we are God’s children now; what we will be has not yet been revealed. What we do know is this: when he is revealed, we will be like him, for we will see him as he is. And all who have this hope in him purify themselves, just as he is pure.

Clement of Alexandria

It leads us to the endless and perfect end, teaching us beforehand the future life that we shall lead, according to God, and with gods; after we are freed from all punishment and penalty which we undergo, in consequence of our sins, for salutary discipline.
