Roman Catechism 3.39

Chapter 3 — Part I: The Creed — Article I: I Believe in God, the Father Almighty, Creator of Heaven and Earth

Section 39. "Creator" — The necessity of having previously imparted to the faithful a knowledge of the omnipotence of God will appear from what we are now about to explain with regard to the creation of the world. The wondrous production of so stupendous a work is more easily believed when all doubt concerning the immense power of the Creator has been removed.
