Jesus Christ
Catholics confess Jesus of Nazareth as the eternal Son made human. The same Person is truly God and truly human, with divine and human natures united without confusion or separation. His life, death, resurrection, and ascension are the heart of the gospel, and the title Mother of God protects the claim about who Mary bore.
Why it matters
Christian worship and salvation depend on the identity and saving work of Christ.
Historical context
Ephesus (431) defended the unity of Christ's person; Chalcedon (451) articulated the confession of one Christ in two natures. Catholic theology receives these councils while acknowledging that other ancient Christian communions use different Christological language.

Primary sources
The council confesses Christ:
Chalcedon's definition holds Christ's two natures together without confusion or division.
in two natures, unconfusedly, immutably, indivisibly, inseparably [united]
Passage context and translation
The definition confesses one and the same Christ in two natures while preserving both their distinction and their union in one person. Oriental Orthodox churches do not receive Chalcedon, even though later dialogues have identified significant shared Christological convictions.

Cyril's anathema states:
Cyril connects the title Theotokos with the confession that Emmanuel is truly God.
the Emmanuel is very God, and that therefore the Holy Virgin is the Mother of God
Passage context and translation
Cyril's first anathema, reproduced among the Ephesian documents, grounds Theotokos in the identity of the one born from Mary: Emmanuel, truly God. This is Cyril's anathema, not a standalone council creed.
