I confess the historic Christian faith for sinners and saints as articulated by the Apostles' Creed and the Nicene Creed.
"But that it may be most easily and clearly understood as it is to be taught to children, we shall briefly sum up the entire Creed in three chief articles, according to the three persons in the Godhead, to whom everything that we believe is related, so that the First Article, of God the Father, explains Creation, the Second Article, of the Son, Redemption, and the Third, of the Holy Spirit, Sanctification. Just as though the Creed were briefly comprehended in so many words: I believe in God the Father, who has created me; I believe in God the Son, who has redeemed me; I believe in the Holy Spirit, who sanctifies me. One God and one faith, but three persons, therefore also three articles or confessions." —Martin Luther
The Apostles' Creed
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 sits at the right hand of God the Father Almighty; from thence He shall come to judge the living and the dead.
I believe in the Holy Spirit; the holy Christian Church, the communion of saints; the forgiveness of sins; the resurrection of the body; and the life everlasting. Amen.
The Nicene Creed
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; by whom all things were made; who for us men, and for our salvation, came down from heaven, and was incarnate by the Holy Spirit 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 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 I believe in the Holy Spirit, the Lord and Giver of life, who proceeds 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 Christian 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.
