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: behold now, thy servant hath found grace in thy sight,” etc. What is meant by his saying to them, “Oh! not so, my lord,” if He who was the Lord had already departed, and had sent the angels? Why is it said, “Oh! not so, my lord,” and not, “Oh! not so, my lords?” Or if he wished to speak to one of them, why does Scripture say, “But Lot said to them, Oh! not so, my lord: behold now, thy servant hath found grace in thy sight,” etc.? Are we here, too, to understand two persons in the plural number, but when the two are addressed as one, then the one Lord God of one substance? But which two persons do we here understand?—of the Father and of the Son, or of the Father and of the Holy Spirit, or of the Son and of the Holy Spirit? The last, perhaps, is the more suitable; for they said of themselves that they were sent, which is that which we say of the Son and of the Holy Spirit. For we find nowhere in the Scriptures that the Father was sent.
