Chapter 3 — Part I — Article I (Of God the Father)
Section 83. Q. What does holy Scripture teach us of the unity of God? A. The very words of the Creed on this point are taken from the following passage of the Apostle Paul: There is none other God but one. For though there be that are called gods, whether in heaven or on earth, as there be gods many, and lords many, but to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him. 1 Cor. viii. 4, 5, 6.
