Athanasius on Theosis

The time will come when some of these boys, through their faithfulness to the gospel, will progress and develop in knowledge, intelligence and power, in future eternities.

The Gods who dwell in heaven . . . were once in a fallen state . . . they were exalted also, from fallen men to celestial Gods.

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.

God became man that man might become God.

Just as the Lord, putting on the body, became a man, so also we men are both deified through his flesh, and henceforth inherit everlasting life.
