Two natures and wills
The one Christ possesses complete divine and human natures, each with its proper natural will.
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
- Philippians 2:6–8 — Branch anchor, interpreted in this tradition: The one Christ possesses complete divine and human natures, each with its proper natural will.
- Luke 22:39-46 — Gethsemane depicts real human anguish and the willing acceptance of the cup. Read the prayer in its narrative setting, not as an isolated technical definition.
- Hebrews 5:7-9 — The Son's prayers, suffering, and learned obedience belong to the saving exercise of his humanity.
- John 6:38-40 — The Son comes to do the Father's will. The passage concerns his saving mission; later theology relates this to personal and natural willing.

- Third Council of Constantinople: Definition of Faith (session XVIII, two natural wills and operations)
The council affirms two natural wills and two natural operations in the one Christ. The human will is not abolished and is not opposed to the divine will. - Gregory of Nazianzus: First Letter to Cledonius against Apollinarius (Epistle 101, completeness of the assumed humanity)
Gregory's earlier argument for a complete human mind supplies an important antecedent, not a seventh-century conciliar definition in advance. - Catechism of the Catholic Church
