God the Father is a title given to God in Christianity. He is regarded as the first person of the Trinity, followed by Jesus Christ and the Holy Spirit. God the Father is the ultimate Creator, Ruler, and Preserver of all things. The Christian's relationship with God is that of a father and child.
Jesus Christ is the Word of God made flesh, who redeemed man by His Death on the Cross, and whose Divine mission is continued by the ministry of the Church. Jesus Christ is truly God, the Second Person of the Trinity, the Son, the Eternal Word who always was, is, and always will be with the Father and Holy Spirit.
