The Definition of Chalcedon
We, now, following the holy Fathers, all with one consent, teach men to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a rational soul and body; of one substance with the Father with respect to his deity, and of one substance with us with respect to his humanity; in all things like unto us, without sin; begotten before all ages of the Father, with respect to his deity, and in these latter days, for us and for our salvation, born of the Virgin Mary, the God-bearer, with respect to his humanity; one and the same Christ, Son, Lord, Only-Begotten, to be acknowledged in two natures, inconfusedly, unchangeably, indivisibly, inseparably; the distinction of natures being by no means taken away by the union, but rather the property 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 Son, and only-begotten, God the Word, the Lord Jesus Christ; as the prophets from the beginning have declared concerning him, and the Lord Jesus Christ himself has taught us, and the Creed of the holy Fathers has handed down to us.
The Apostles’ Creed (CA. 125)
I believe in God, the Father Almighty, Creator of heaven and earth, and in Jesus Christ, his only-begotten Son, our Lord: Who was conceived of the Holy Spirit, born of the Virgin Mary; suffered under Pontius Pilate, crucified, died, and was buried; descended into hell; the third day he rose from the dead; ascended into heaven, sits at the right hand of God the Father Almighty, from where he shall come to judge the living and the dead. I believe in the Holy Spirit, the holy catholic church, the communion of saints, the forgiveness of sins, the resurrection of the flesh, and life everlasting.
The Niceno-Constantinopolitan Creed (381)
We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord Jesus Christ, the only Son of God, begotten of the Father before all ages; Light of Light, true God of true God; begotten, not made, of one substance with the Father; through whom all things were made.
Who, for us human beings and for our salvation, came down from heaven, and was made flesh by the Holy Spirit and the virgin Mary, and was made a human being; was crucified also for us under Pontius Pilate; and suffered, and was buried; and the third day rose again, according to the Scriptures; and ascended into heaven, and sits on the right hand of the Father; and will come again with glory to judge the living and the dead; whose kingdom will have no end.
And in the Holy Spirit, the Lord, the Giver of Life; who proceeds from the Father; who together with the Father and the Son is worshipped and glorified; who spoke through the prophets.
In one holy, catholic, and apostolic church.
We confess one baptism for the remission of sins.
We look for the resurrection of the dead, and the life of the world to come. Amen.
