The Incarnation is the central mystery of the Christian faith: the eternal, uncreated Word of God — the second Person of the Trinity — took on full human nature without ceasing to be fully God. "The Word became flesh and dwelt among us, and we have seen his glory" (John 1:14). Paul declares: "Great indeed, we confess, is the mystery of godliness: He was manifested in the flesh" (1 Timothy 3:16). In the Incarnation, God did not merely appear human — He became human, born of a woman, subject to hunger, weariness, temptation, suffering, and death. Yet He remained fully divine: two natures in one Person, without confusion, without change, without division, without separation. This is the hinge of redemption — only one who is both God and man can mediate between God and men.
The act of assuming flesh, or of taking a human body and the nature of man; applied to Christ.
INCARNATION, n. [L. incarnatio.] 1. The act of clothing with flesh. 2. The act of assuming flesh, or of taking a human body and the nature of man; as the incarnation of the Son of God. Webster understood the Incarnation as the unique, unrepeatable act of God becoming man in Jesus Christ.

The Incarnation is either denied outright or sentimentalized into irrelevance.
Liberal theology denies the literal Incarnation, treating it as a metaphor for God's solidarity with humanity. The virgin birth is dismissed as mythological, and Jesus is reduced to a teacher or prophet. On the other extreme, prosperity theology treats the Incarnation as proof that God wants believers to have material abundance — missing entirely that God became flesh to suffer and die. The Incarnation is the most staggering claim in all of history: the infinite, eternal Creator entered His own creation as a helpless infant, lived among sinners, and died in their place. Any theology that domesticates this mystery into a comfortable life philosophy has not understood it.
• "The Incarnation is not God wearing a human costume — it is God becoming fully human while remaining fully divine, two natures united in one Person forever."
• "Without the Incarnation there is no atonement — only one who is both God and man can stand between God and men as Mediator."
• "The mystery of godliness is not a riddle to be solved but a reality to be worshiped — God was manifested in the flesh."
