Mother of God
Mary is Mother of God because her child is the one divine Son incarnate.
Why it matters
This branch belongs to Christ & Mary: Catholic Marian teaching is Christological and ecclesial: Mother of God, perpetual virginity, Immaculate Conception, and Assumption are distinct claims with distinct histories.
Historical context
The early councils define Christological grammar; later papal definitions articulate the Immaculate Conception and Assumption within Catholic reception.
Tradition note
This is a Catholic introduction. Latin and Eastern Catholic churches share communion while differing in liturgical and theological expression.
Memory hook
Everything affirmed of Mary serves the identity and saving work of Christ.

Scripture
- Luke 1:43 — Branch anchor, interpreted in this tradition: Mary is Mother of God because her child is the one divine Son incarnate.
- 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.
