Psalm 82:6 (NRSV) — Theosis

Augustine of Hippo

But he himself that justifies also deifies, for by justifying he makes sons of God. “For he has given them power to become the sons of God.” If then we have been made sons of God, we have also been made gods.

And they shall pass by the angels, and the gods, which are set there, to their exaltation and glory in all things, as hath been sealed upon their heads, which glory shall be a fulness and a continuation of the seeds forever and ever.

Hippolytus

You will be a companion of God, and a co-heir with Christ . . . For you have become divine . . . God has promised to bestow these upon you, for you have been deified and begotten unto immortality.
