Divinization (Christian)

Arguably the most prolific of the medieval scholastic theologians, St. Thomas Aquinas, wrote:

Now the gift of grace surpasses every capability of created nature, since it is nothing short of a partaking of the Divine Nature, which exceeds every other nature. And thus it is impossible that any creature should cause grace. For it is as necessary that God alone should deify, bestowing a partaking of the Divine Nature by a participated likeness, as it is impossible that anything save fire should enkindle.^{[Primary 19]}

At about the same time, Clement of Alexandria (c. 150–215), wrote: "Yea, I say, the Word of God became a man so that you might learn from a man how to become a god."^[5] Clement further stated that "[i]f one knows himself, he will know God, and knowing God will become like God. . . . His is beauty, true beauty, for it is God, and that man becomes a god, since God wills it. So Heraclitus was right when he said, 'Men are gods, and gods are men.'"^[6] Clement of Alexandria also stated that "he who obeys the Lord and follows the prophecy given through him ... becomes a god while still moving about in the flesh."^[7]

According to Heraclitus, "Mortals are immortals and immortals are mortals, the one living the others' death and dying the others' life".^[77] This is taken to mean men are mortal gods and gods are immortal men.^[55]
