theosis

If you, free as you are of every weighthad stayed below, then that would be as strangeas living flame on earth remaining still."And then she turned her gaze up toward the heavens.

[God] sees before Him in fact a self-centred, greedy, grumbling, rebellious human animal. But He says "Let us pretend that this is not a mere creature, but our Son. It is like Christ in so far as it is a Man, for He became Man. Let us pretend that it is also like Him in Spirit. Let us treat it as if it were what in fact it is not. Let us pretend in order to make the pretence into a reality." God looks at you as if you were a little Christ: Christ stands beside you to turn you into one. I daresay this idea of a divine makebelieve sounds rather strange at first. But, is it so strange really? Is not that how the higher thing always raises the lower? A mother teaches her baby to talk by talking to it as if it understood long before it really does.

Dusty, dark, cold, and hard, coal has no beauty of its own, but when it is consummated by fire it is beautiful and becomes what it was designed to be.

He who aspires to divine realities willingly allows providence to lead him by principle of wisdom toward the grace of deification. He who does not so aspire is drawn, by the just judgement of God and against his will, away from evil by various forms of discipline. The first, as a lover of God, is deified by providence; the second, although a lover of matter, is held back from perdition by God's judgement. For since God is goodness itself, he heals those who desire it through the principles of wisdom, and through various forms of discipline cures those who are sluggish in virtue.

The crucial distinction can be discerned by differentiating between deification, an ontological sharing in the Godhead in which the human literally becomes divine, and theosis, a participation in the life of God the Father through union with Jesus Christ by the power of the Holy Spirit which the human becomes truly human.
