Definition of Chalcedon

Following the holy fathers, we teach with one voice that the Son of God and our Lord Jesus Christ is to be confessed as one and the same Person,

That He is perfect in Godhead and perfect in manhood, truly God and truly man, of a reasonable soul and body consisting of one substance with the Father as regards His Godhead, and at the same time of one substance with us as regards His manhood, like us in all respects, apart from sin.

Begotten of His Father before the ages as regards His Godhead,

But in these last days born for us and for our salvation of the Virgin Mary, the God- bearer.

This one and the same Jesus Christ, the only-begotten Son of God, must be confessed to be in two natures, without confusion, without changes, without division, not as parted or separated into two persons, but one and the same Son and only-begotten God the Word, our Lord Jesus Christ.

Even as the prophets from earliest times spoke of Him, And our Lord Jesus Christ Himself taught us,
And the creed of the fathers has handed down to us.
