Theotokos
Mary is Theotokos because the one born from her is the divine Son incarnate, not because she originates his divinity.
Why it matters
This branch belongs to Christ & Theotokos: The title Theotokos protects the unity of Christ, and the saving significance of every part of human nature depends on its being assumed by the Word.
Historical context
Ephesus, Chalcedon, and Constantinople III supply the conciliar grammar received in Orthodox Christology.
Tradition note
This is a Chalcedonian Eastern Orthodox introduction. Local usages vary among autocephalous churches.
Memory hook
One Christ, fully God and fully human, without confusion or separation.

Scripture
- Luke 1:43 — Branch anchor, interpreted in this tradition: Mary is Theotokos because the one born from her is the divine Son incarnate, not because she originates his divinity.
- Luke 1:39-45 — Elizabeth calls Mary the mother of her Lord in the visitation narrative. This is a biblical anchor for the title, not the later conciliar term itself.
- Galatians 4:4-7 — God sends his Son, born of a woman and under the law, so that others receive adoption.
- John 1:1-14 — The one born in flesh is identified with the pre-existent Word. The title concerns who is born, not a beginning of the divine nature.
