Roman Catechism 3.34

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

Section 34. Besides, nothing tends more to confirm our faith and animate our hope than a deep conviction that all things are possible to God; for whatever may be afterwards proposed as an object of faith, however great, however wonderful, however raised above the natural order, is easily and without hesitation believed, once the mind has grasped the knowledge of the omnipotence of God. Nay more, the greater the truths which the divine oracles announce, the more willingly does the mind deem them worthy of belief. And should we expect any favour from heaven, we are not discouraged by the greatness of the desired benefit, but are cheered and confirmed by frequently considering that there is nothing which an omnipotent God cannot effect.
