True God and true man in one divine person: two natures united without confusion, change, division, or separation.
Fully God and fully man — compare how six traditions confess who Jesus Christ is.
Christianity stands or falls on the claim that Jesus of Nazareth is both fully God and fully man — the eternal Word made flesh. The Council of Chalcedon (451) gave the Church its enduring formula: one person in two natures, divine and human, united “without confusion, without change, without division, without separation.” All six traditions receive Chalcedon, and all confess the virgin birth and Christ’s sinless humanity. Their differences lie in emphasis: how the two natures relate, what the union means for worship and the sacraments, and why the God-man had to be exactly who he is to save.
In 30 seconds
All six traditions confess the same Chalcedonian faith: Jesus Christ is one person who is fully God and fully man — two natures united “without confusion, without change, without division, without separation.” The differences are in emphasis. Catholics and Orthodox stress that Mary is therefore Theotokos, Mother of God, and the Orthodox add that the incarnation deifies human nature: God became man so that man might become god by grace. Lutherans teach the communication of attributes — Christ’s human nature shares in the divine majesty. The Reformed insist the natures remain distinct, the human nature not made omnipresent. Baptists and Methodists confess the virgin-born God-man as the only Savior, whose sinless obedience and substitutionary death ground our redemption.

| Lutheran | Two natures inseparably joined in one person, with a real communication of attributes — the God-man truly present. |
| Reformed | Very God and very man, yet one Christ: two distinct natures inseparably joined in one person, without mixture. |
| Baptist | The eternal Son conceived by the Spirit and born of the virgin Mary — fully God, fully man, without sin, our only Savior. |
| Methodist | Very God and very Man in one person, never to be divided — the God-man whose atonement is the miracle of redeeming love. |
