What the Church teaches
Jesus Christ is one divine person in two natures, divine and human, without confusion, change, division or separation.
The Incarnation happened in history, not at the council. Chalcedon in 451 gave a precise confession of the identity of the one born of Mary: the same Son is fully divine and fully human. He is not half of each, nor a human person living beside the Son of God.
He has a real human body, a rational human soul and a human will. He grows, suffers, loves and obeys in our humanity. His human will is not erased by his divinity; the later teaching of Constantinople III safeguards two natural wills united in the one person of the Son.
Mary is Theotokos, Mother of God, because the person she bore is the eternal Son. This does not mean that she originated his divinity. The Marian title protects the identity of Jesus and connects this guide directly to the Marian dogma.
Sacred Scripture
John 1:14
The Word became flesh and dwelt among us. Human existence is assumed, not merely worn as a disguise.
Philippians 2:6–11
The one in the form of God takes the form of a servant and freely accepts the Cross.
Hebrews 4:15
Christ truly shares our human condition and temptation, yet without sin.
Church documents & Catechism
Why the Word became flesh; true God and true man; Christ’s soul, knowledge and will.
The two natures retain their proper reality in the unity of one person.
With the saints · East & West
“Christian, acknowledge your dignity”
Leo grounds Christian dignity in the Incarnation: the Son truly took our nature and calls us to a life worthy of the grace we have received, rather than a return to slavery to sin.
“For He was made man that we might be made God.”
The Eastern language of divinization means sharing in God’s life by grace, not becoming another god by nature. Only the truly divine Son can give this participation in divine life.
Questions & Catholic answers
Did God stop being God?
No. The Son assumes a human nature without losing or changing his divine nature. His self-emptying is the humility of love, not the surrender of divinity.
Are there two persons in Jesus?
No. The acting subject is the one eternal Son, living and acting according to both his divine and his human nature.
Word made flesh, teach me to welcome you with the faith of Mary and to honour the dignity of every person. Amen.
