Genesis 19 (chosen pages)
(Gen 19, 1-3) The two angels reached Sodom gate
[1] The two angels reached Sodom in the evening, as Lot was sitting at the gate of Sodom. When Lot saw them, he got up to greet them; and bowing down with his face to the ground, [2] he said, "Please, gentlemen, come aside into your servant's house for the night, and bathe your feet; you can get up early to continue your journey." But they replied, "No, we shall pass the night in the town square." [3] He urged them so strongly, however, that they turned aside to his place and entered his house. He prepared a meal for them, baking cakes without leaven, and they dined.
(CCC 328) The existence of the spiritual, non-corporeal beings that Sacred Scripture usually calls "angels" is a truth of faith. The witness of Scripture is as clear as the unanimity of Tradition. (CCC 330) As purely spiritual creatures angels have intelligence and will: they are personal and immortal creatures, surpassing in perfection all visible creatures, as the splendour of their glory bears witness (Cf. Pius XII, Humani generis: DS 3891; Lk 20:36; Dan 10:9-12). (CCC 332) Angels have been present since creation and throughout the history of salvation, announcing this salvation from afar or near and serving the accomplishment of the divine plan: they closed the earthly paradise; protected Lot; saved Hagar and her child; stayed Abraham's hand; communicated the law by their ministry; led the People of God; announced births and callings; and assisted the prophets, just to cite a few examples (Cf. Job 38:7 (where angels are called "sons of God"); Gen 3:24; 19; 21:17; 22:11; Acts 7:53; Ex 23:20-23; Judg 13; 6:11-24; Isa 6:6; 1 Kings 19:5). Finally, the angel Gabriel announced the birth of the Precursor and that of Jesus himself (Cf. Lk 1:11, 26).
