CCC 392

Scripture speaks of a sin of these angels. Cf. 2 Pt 2:4. This "fall" consists in the free choice of these created spirits, who radically and irrevocably rejected God and his reign. We find a reflection of that rebellion in the tempter's words to our first parents: "You will be like God." Gen 3:5. The devil "has sinned from the beginning"; he is "a liar and the father of lies". I Jn 3:8; Jn 8:44.
