CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 274–277

274 "Nothing is more apt to confirm our faith and hope than holding it fixed in our minds that nothing is impossible with God. Once our reason has grasped the idea of God's almighty power, it will easily and without any hesitation admit everything that [the Creed] will afterwards propose for us to believe - even if they be great and marvelous things, far above the ordinary laws of nature."
275 With Job, the just man, we confess: "I know that you can do all things, and that no purpose of yours can be thwarted" (Job 42:2).
276 Faithful to the witness of Scripture, the Church often addresses her prayer to the "almighty and eternal God" ("omnipotens sempiterne Deus. .."), believing firmly that "nothing will be impossible with God" (Gen 18:14; Lk 1:37; Mt 19:26).
277 God shows forth his almighty power by converting us from our sins and restoring us to his friendship by grace. "God, you show your almighty power above all in your mercy and forgiveness. . ." (Roman Missal, 26th Sunday, Opening Prayer).
