κένωσις

Kénōsis comes from the Greek verb kenoein (to empty), from kenós (empty). The theological concept originates in Paul's letter to the Philippians (2:6-7), where he writes that Christ, 'being in the form of God, did not consider equality with God something to be grasped, but emptied himself, taking the form of a servant.' The Greek word Paul uses is ekénōsen — he emptied himself. The noun kénōsis was built from this passage and became a technical term in Christological debate.

The theological problem was enormous. If Christ was fully God, what did it mean for God to 'empty himself'? Did he surrender omniscience? Omnipotence? Did he retain divine attributes while setting them aside? The question occupied church councils for centuries. Cyril of Alexandria in the fifth century argued that the emptying was voluntary self-limitation, not subtraction. The divine nature remained complete but was hidden. Lutheran theologians in the seventeenth century pushed further, arguing that Christ genuinely gave up some divine attributes during the Incarnation.

Nineteenth-century German theologians — particularly Gottfried Thomasius in 1845 — developed full-blown kenotic theology, arguing that God's self-emptying was the most radical act of love imaginable: omnipotence choosing helplessness, omniscience choosing ignorance, infinity choosing the limitations of a human body. The word kenosis named the paradox at the center of Christian theology: a God who is most divine when least powerful.

The concept has been adopted outside theology. Philosophers use kenosis to describe any act of self-emptying for the sake of another. Psychologists reference it in discussions of ego dissolution. Artists speak of kenotic creativity — emptying the self to let the work emerge. The Greek word for emptying became a word for the highest possible form of giving: giving up the self.
