Definition of Chalcedon
(451 AD)
Following, then, the holy fathers, we unite in
teaching all
men to confess the one and same Son, our Lord Jesus Christ. This
selfsame one
is perfect both in deity and in humanity; truly God and truly man, with
a
rational soul and a body; consubstantial with the Father according to
His
deity, and consubstantial with us according to the humanity; like us in
all
respects, sin only excepted.
Before the ages He was begotten of the Father,
according to
the deity, and in these last days, for us and for our salvation, He was
born of
Mary the virgin, who is Godbearer according to His humanity; one and
the same
Christ, Son, Lord, only-begotten, to be acknowledge in two natures;
without
confusing them, without interchanging them, without dividing them, and
without
separating them; the distinction of natures by no means taken away by
the
union, but the properties of each nature being preserved, and
concurring in one
Person and one subsistence; not parted or divided into two persons, but
one and
the same only-begotten Son, the Lord Jesus Christ, as from the
beginning the
prophets have declared concerning Him, and the Lord Jesus Christ
Himself has
taught us, and the symbol of the fathers has handed down to us.
