I replied again, “If I could not have proved to you from the Scriptures that one of those three is God, and is called Angel, because, as I already said, He brings messages to those to whom God the Maker of all things wishes [messages to be brought], then in regard to Him who appeared to Abraham on earth in human form in like manner as the two angels who came with Him, and who was God even before the creation of the world, it were reasonable for you to entertain the same belief as is entertained by the whole of your nation.”
“… And now have you not perceived, my friends, that one of the three, who is both God and Lord, and ministers to Him who is in the heavens, is Lord of the two angels?”
Justin Martyr
