It is a serious thing to live in a society of possible gods and goddesses.
—from “The Weight of Glory”
When he was president of the Oxford Socratic Club during the 1940s and 50s, C.S. Lewis featured weekly discussions on “repellent doctrines.” By these, he meant traditional Christian teachings that seemed puzzling or implausible—teachings on suffering, miracles, hierarchy, and the like. Lewis thought these doctrines conveyed truths that modern people most needed to know but were least likely to recognize: “We must never avert our eyes from those elements in [our religion] which seem puzzling or repellent; for it will be precisely the puzzling or the repellent which conceals what we do not yet know and need to know.”1 For many Christians today, deification would be such a doctrine. Deification (also known as theosis or divinization) sees salvation not merely as divine pardon but rather as a process of spiritual transformation that culminates in mystical union with God. As Lewis understood it, human beings could one day enter into the very beauty and energy of God and become “true and everlasting and really divine persons.”2 In his book Mere Christianity, which can be seen as a manifesto on the subject, Lewis argues that the whole purpose of Christianity is to turn people into what he variously calls “new men,” “little Christs,” “Sons of God”—and “gods and goddesses.”
