Our basis of unity is the Lordship of Jesus Christ. Below are the two earliest universal Christian creeds, accepted as accurate statements of scriptural truth by all three major branches of the church, Orthodox, Roman Catholic, and Protestant.
I believe in God the Father Almighty, maker of heaven and earth;
And in Jesus Christ his only Son our Lord: who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, dead, and buried; he descended into hell;* the third day he rose again from the dead; he ascended into heaven, and sitteth at the right hand of God the Father Almighty; from thence he shall come to judge the quick 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 body, and the life everlasting. Amen.
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 only begotten Son of God: begotten of the Father before all worlds, God of God, Light of Light, very God of very God, begotten, not made, being of one substance with the Father, through whom all things were made; 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, and was crucified also for us under Pontius Pilate; he 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; and he shall come again with glory, to judge both the quick and the dead; whose kingdom shall have no end.
And I believe in the Holy Ghost, the Lord, the giver of life, who proceedeth from the Father and the Son,* who with the Father and the Son together is worshiped and glorified, who spake by the prophets.
And I believe in one holy catholic and apostolic Church. I acknowledge one baptism for the remission of sins. And I look for the resurrection of the dead, and the life of the world to come. Amen.* italicized phrases added subsequently and accepted by many churches
