Incarnation
The eternal Son became truly human while remaining fully divine.
Why it matters
This branch belongs to Gospel Of Christ: Protestant preaching often organizes Christology around the gospel announcement and Christ's offices as prophet, priest, and king.
Historical context
The early creeds remain foundational, while Reformation confessions sharpen accounts of mediation, atonement, and the communication of Christ's natures.
Tradition note
Protestantism has no single worldwide teaching office. This map distinguishes major confessional families and cannot represent every independent church.
Memory hook
The gospel announces a living Lord, not an isolated atonement theory.

Primary sources

Gregory of Nazianzus is a source witness for this study: A complete humanity, not a divine disguise.
For that which He has not assumed He has not healed; but that which is united to His Godhead is also saved.
Passage context and translation
Gregory rejects Apollinarianism by insisting that the Word assumed the fullness of human nature, including a human mind.
Before the excerpt
If anyone has put his trust in Him as a Man without a human mind, he is really bereft of mind, and quite unworthy of salvation.
After the excerpt
If only half Adam fell, then that which Christ assumes and saves may be half also; but if the whole of his nature fell, it must be united to the whole nature of Him that was begotten, and so be saved as a whole.

- Council of Chalcedon: Definition of Faith (session V, definition)
The definition confesses one and the same Son, complete in divinity and humanity, with a rational soul and body, in two natures without confusion or division. - Gregory of Nazianzus: First Letter to Cledonius against Apollinarius (Epistle 101)
Gregory opposes a Christ without a human mind: what is not assumed is not healed. This is an argument about the completeness of salvation, not merely a slogan about embodiment. - Augsburg Confession
