The miraculous act by which the eternal Son of God — the second Person of the Trinity — took on a complete human nature, becoming fully God and fully man in the person of Jesus Christ. He was not merely a spiritual being who appeared human, nor a man who became divine, but the infinite God who entered finite creation without ceasing to be God. The Incarnation is the hinge of all human history: God dwelling with us (Emmanuel) in flesh, born of a virgin, to accomplish what no mere man could — perfect obedience, atoning sacrifice, and triumphant resurrection.
INCARNA'TION, n. The act of assuming flesh, or of taking a human body and the nature of man; as the incarnation of the Son of God. The doctrine of the incarnation is a fundamental article of the Christian faith, affirming that the Word was made flesh and dwelt among us.
Modern culture uses "incarnation" loosely — as a metaphor for any "embodiment" of an idea, a product, or a celebrity persona ("the latest incarnation of the franchise"). Some New Age spiritualities borrow the word for reincarnation cycles, stripping it of its unique, once-for-all historical meaning. Liberal theology re-frames the Incarnation as merely a symbol of God's solidarity with humanity, denying the ontological reality: that Jesus is literally, physically God in flesh.

"To deny the Incarnation is to deny Christianity itself; Paul warns that any spirit refusing to confess Christ come in the flesh is the spirit of antichrist (1 John 4:2–3)."
"The Incarnation forever dignifies human embodiment — God himself wore a human body, and that body was raised on the third day."
