Creed of Nicea (325)

Creed of Constantinople (381)

We believe in one God, the Father Almighty, Maker of all things visible and invisible.

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 Son of God, begotten of the Father [the only-begotten; that is, of the essence of the Father, God of God], Light of Light, very God of very God, begotten, not made, being of one substance with the Father;

And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before allworlds (æons), Light of Light, very God of very God, begotten, not made, being of one substance with the Father;

By whom all things were made [both in heaven and on earth];

by whom all things were made;

Who for us men, and for our salvation, came down and was incarnate and was made man;

who for us men, and for our salvation, came down from heaven, and was incarnate by the Holy Ghost of the Virgin Mary, and was made man;

He suffered, and the third day he rose again, ascended into heaven;

he was crucified for us under Pontius Pilate, and suffered, and was buried, and the third day he rose again, according to the Scriptures, and ascended into heaven, and sitteth on the right hand of the Father;

From thence he shall come to judge the quick and the dead.

from thence he shall come again, with glory, to judge the quick and the dead;

whose kingdom shall have no end.

And in the Holy Ghost.

And in the Holy Ghost, the Lord and Giver of life, who proceedeth from the Father, who with the Father and the Son together is worshiped and glorified, who spake by the prophets.

In one holy catholic and apostolic Church; we acknowledge one baptism for the remission of sins; we look for the resurrection of the dead, and the life of the world to come. Amen.

[But those who say: 'There was a time when he was not;' and 'He was not before he was made;' and 'He was made out of nothing,' or 'He is of another substance' or 'essence,' or 'The Son of God is created,' or 'changeable,' or 'alterable'—they are condemned by the holy catholic and apostolic Church.]

Creed of Chalcedon (451)

We, then, following the holy Fathers, all with one consent, teach people 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 reasonable [rational] soul and body;

consubstantial [co-essential] with the Father according to the Godhead, and consubstantial with us according to the Manhood;

in all things like unto us, without sin;

begotten before all ages of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the Virgin Mary, the Mother of God, according to the Manhood;

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 (μονογενῆ Θεὸν), 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.
