I 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, the only-begotten, begotten of the Father before all ages. Light of light; true God of true God; begotten, not made; of one essence with the Father, by Whom all things were made; Who for us men and for our salvation came down from Heaven, and was incarnate of the Holy Spirit and the Virgin Mary, and became man. And He was crucified for us under Pontius Pilate, and suffered, and was buried. And the third day He arose again, according to the Scriptures, and ascended into Heaven, and sits at the right hand of the Father; and He shall come again with glory to judge the living and the dead; Whose Kingdom shall have no end.

And in the Holy Spirit, the Lord, the Giver of Life, Who proceeds from the Father; Who with the Father and the Son together is worshipped and glorified; Who spoke by the prophets.

In one Holy, Catholic, and Apostolic Church. I acknowledge one baptism for the remission of sins. I look for the resurrection of the dead and the life of the world to come. Amen.

The Nicene-Constantinopolitan Creed

The Nicene Creed is the most authoritative declaration of the Orthodox Faith. It clearly proclaims the Trinity and Incarnation. God is three persons–the Father, the Son, and the Holy Spirit. Within time, and from a virgin mother, the only begotten Son of God became human in the fullest way possible to unite God and humanity together for the salvation of humanity lived out today through the Church.

Through this union with Christ and his saving work, humanity now has been delivered from death and granted life with God through the Son in the Holy Spirit, such that we can become “partakers of the divine nature” by His grace.
