Following the holy Fathers, we unanimously teach and confess
one and the same Son, our Lord Jesus Christ: the same perfect
in divinity and perfect in humanity, the same truly God and
trulyman, composedof rational soul andbody; consubstantial
with the Father as to his divinity and consubstantial with us as
to his humanity; “like us in all things but sin.”Hewas begotten
from the Father before all ages as to his divinity and in these
last days, for us and for our salvation, was born as to his
humanity of the virgin Mary, the Mother of God.
We confess that one and the same Christ, Lord, and only-be
gotten Son, is to be acknowledged in two natures without
confusion, change, division, or separation. The distinction
between the natures was never abolished by their union, but
rather the character proper to each of the two natures was
preserved as they came together in one person (
After the Council of Chalcedon, some made of Christ’s
human nature a kind of personal subject. Against them, the fifth
ecumenical council at Constantinople in 553 confessed that “there
is but one
[or person], which is our Lord Jesus Christ, one
of the Trinity.”
Thus everything in Christ’s human nature is to be
attributed to his divine person as its proper subject, not only his
miracles but also his sufferings and even his death: “He who was
crucified in the flesh, our Lord Jesus Christ, is true God, Lord of
one of the Holy Trinity.
The Church thus confesses that Jesus is inseparably true
God and true man. He is truly the Son of God who, without ceasing
to be God and Lord, became a man and our brother:
“What he was, he remained and what he was not, he as-
sumed,” sings the Roman Liturgy.
And the liturgy of St.
John Chrysostom proclaims and sings: “O only-begotten Son
and Word of God, immortal being, you who deigned for our
salvation to become incarnate of the holy Mother of God and
ever-virgin Mary, you who without change became man and
were crucified, O Christ our God, you who by your death
have crushed death, you who are one of the Holy Trinity,
glorified with the Father and the Holy Spirit, save us!”
