Genesis 19:16

Then I replied, “You are aware, then, that the Scripture says, ‘And the Lord said to Abraham, Why did Sarah laugh, saying, Shall I truly conceive? for I am old. Is anything impossible with God? At the time appointed shall I return to thee according to the time of life, and Sarah shall have a son.’ And after a little interval: ‘And the men rose up from thence, and looked towards Sodom and Gomorrah; and Abraham went with them, to bring them on the way. And the Lord said, I will not conceal from Abraham, my servant, what I do.’ And again, after a little, it thus says: ‘The Lord said, The cry of Sodom and Gomorrah is great, and their sins are very grievous. I will go down now, and see whether they have done altogether according to their cry which has come unto me; and if not, that I may know. And the men turned away thence, and went to Sodom. …

God appeared again to Abraham at the oak of Mamre in three men, who it is not to be doubted were angels, although some think that one of them was Christ, and assert that He was visible before He put on flesh. Now it belongs to the divine power, and invisible, incorporeal, and incommutable nature, without changing itself at all, to appear even to mortal men, not by what it is, but by what is subject to it. And what is not subject to it? Yet if they try to establish that one of these three was Christ by the fact that, although he saw three, he addressed the Lord in the singular, as it is written, “And, lo, three men stood by him: and, when he saw them, he ran to meet them from the tent-door, and worshipped toward the ground, and said, Lord, if I have found favor before thee,” etc.; why do they not advert to this also, that when two of them came to destroy the Sodomites, while Abraham still …

22. Yet, again, it is objected that except they were known to be angels of God, Lot would not have bowed himself with his face to the ground. Why, then, is both hospitality and food offered to them, as though they wanted such human succor? But whatever may here lie hid, let us now pursue that which we have undertaken. Two appear; both are called angels; they are invited plurally; he speaks as with two plurally, until the departure from Sodom. And then Scripture goes on to say, “And it came to pass, when they had brought them forth abroad, that they said, Escape for thy life; look not behind thee, neither stay thou in all the plain; escape to the mountain, and there thou shalt be saved, lest thou be consumed. And Lot said unto them, Oh! not so, my lord: be hold now, thy servant hath found grace in thy sight,” etc. …

1. I am induced to write to you, a stranger to a stranger, by the entreaties of that holy servant of Christ Hedibia and of my daughter in the faith Artemia, once your wife but now no longer your wife but your sister and fellow-servant. Not content with assuring her own salvation she has sought yours also, in former days at home and now in the holy places. She is anxious to emulate the thoughtfulness of the apostles Andrew and Philip; who after Christ had found them, desired in their turn to find, the one his brother Simon and the other his friend Nathanael. …
