Kenosis

Somewhere in the first generation, Christians were already singing it: he was in the form of God, he emptied himself, he took the form of a slave, he went down to death on a cross, and God exalted him above every name. Philippians 2:5–11 — the Carmen Christi — may be the oldest Christian hymn we possess, and its center is one shocking reflexive verb: he emptied himself. The noun the Church built from it, kenōsis, names the deepest mystery of the Incarnation from the inside.

The hymn — a V-shaped gospel

The passage falls like a V: pre-existent glory (“in the form of God… equality with God”), the descent (emptied himself, servant, human, obedient, crucified), then the upswing (“therefore God has highly exalted him… every knee shall bow”). Paul quotes it not as speculation but as ethics — “have this mind among yourselves” — which is itself remarkable: the earliest church reached for the deity of Christ to teach humility. The hymn ends by giving Jesus “the name above every name” and the worship of Isaiah 45:23 — verses written about YHWH alone.

Emptied of what? — the question Paul left open

Paul writes “he emptied himself” and attaches no object — emptied of WHAT? The grammar answers with participles, not a list of surrendered attributes: he emptied himself by taking — taking the form of a servant, being born in human likeness. The emptying is a mode of taking. The Fathers drew the conclusion that has remained the Church's center of gravity: the Son gave up no divinity; he veiled glory and assumed weakness. As the formula puts it, he became what he was not without ceasing to be what he was.

“Remaining what he was, he became what he was not.” — Gregory of Nazianzus, on the Incarnation

The kenotic theories — and the cost of subtraction

Nineteenth-century theologians (Thomasius and the “kenoticists,” mostly Lutheran, later some Anglicans) proposed real subtraction: in becoming man the Son laid aside the “relative” attributes — omniscience, omnipotence, omnipresence — keeping only the “essential” ones. The theory honored texts like Mark 13:32 (the Son does not know the day) and the real weariness, hunger, and tears of the Gospels. But the price is steep: a Son emptied of divine attributes is no longer homoousios with the Father during the incarnation — and if the Son ceased upholding the universe (Heb 1:3; Col 1:17), who held it? The classical alternative explains the limitation texts through the two natures: the one person lives a fully human life — including a human mind that learns and does not know — without the divine nature switching off. Chalcedon's “without confusion, without change” is the fence here.

Kenosis as revelation, not concealment only

There is a deeper patristic note worth hearing: the self-emptying does not merely hide God; it shows him. “Though he was rich, yet for your sake he became poor” (2 Cor 8:9) — the descent is what divine love looks like when it moves. The towel and basin of John 13 are not God acting out of character but God's character enacted. The cross does not interrupt the glory of the Son; in John's Gospel it IS the hour of glory. Kenosis tells us not only what the Son gave up, but what God is like: the One whose form is most truly seen stooping.

Why it still matters

Kenosis is the hinge between doctrine and discipleship. Paul's point in quoting the hymn is “let this mind be in you”: the downward mobility of the Son is the pattern of the Christian life — status surrendered, service embraced, exaltation left to God. Wherever the church grasps at platforms and thrones, Philippians 2 stands as the oldest hymn and the standing rebuke: the way up is down, because that is the way God himself came.
