you believe in God the Father Almighty?" And the one being baptized shall answer, "I
believe." He shall then baptize each of them once, laying his hand upon each of their
heads. Then he shall ask, "Do you believe in Jesus Christ, the Son of God, who was
born of the Holy Spirit and the Virgin Mary, who was crucified under Pontius Pilate, and
died, and rose on the third day living from the dead, and ascended into heaven, and sat
down at the right hand of the Father, the one coming to judge the living and the dead?"
