Genesis 18:1

“Moses, then, the blessed and faithful servant of God, declares that He who appeared to Abraham under the oak in Mamre is God, sent with the two angels in His company to judge Sodom by Another who remains ever in the supercelestial places, invisible to all men, holding personal intercourse with none, whom we believe to be Maker and Father of all things; for he speaks thus: ‘God appeared to him under the oak in Mamre, as he sat at his tent-door at noontide. …

4. Therefore have the Jews departed from God, in not receiving His Word, but imagining that they could know the Father [apart] by Himself, without the Word, that is, without the Son; they being ignorant of that God who spake in human shape to Abraham, and again to Moses, saying, “I have surely seen the affliction of My people in Egypt, and I have come down to deliver them.” For the Son, who is the Word of God, arranged these things beforehand from the beginning, the Father being in no want of angels, in order that He might call the creation into being, and form man, for whom also the creation was made; nor, again, standing in need of any instrumentality for the framing of created things, or for the ordering of those things which had reference to man; while, [at the same time,] He has a vast and unspeakable number of servants. …

34. Unless, perhaps, some one shall say, that the Father is therefore not visible, because He appeared within the sight of one who was dreaming; but that therefore the Son and the Holy Spirit are visible, because Moses saw all those things being awake; as if, forsooth, Moses saw the Word and the Wisdom of God with fleshly eyes, or that even the human spirit which quickens that flesh can be seen, or even that corporeal thing which is called wind; how much less can that Spirit of God be seen, who transcends the minds of all men, and of angels, by the ineffable excellence of the divine substance? Or can any one fall headlong into such an error as to dare to say, that the Son and the Holy Spirit are visible also to men who are awake, but that the Father is not visible except to those who dream? How, then, do they understand that of the Father alone, “Whom no man hath seen, nor can see.”? Whe …

25. Can there be any one who will say that the Lord appeared to Moses by an angel, but to Abraham by Himself? Let us not answer this question from Stephen, but from the book itself, whence Stephen took his narrative. For, pray, because it is written, “And the Lord God said unto Abraham;” and a little after, “And the Lord God appeared unto Abraham;” were these things, for this reason, not done by angels? Whereas it is said in like manner in another place, “And the Lord appeared to him in the plains of Mamre, as he sat in the tent door in the heat of the day;” and yet it is added immediately, “And he lift up his eyes and looked, and, lo, three men stood by him:” of whom we have already spoken. …

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. …

16. Was it without reason that Christ was made Man? Are our teachings ingenious phrases and human subtleties? Are not the Holy Scriptures our salvation? Are not the predictions of the Prophets? Keep then, I pray thee, this deposit undisturbed, and let none remove thee: believe that God became Man. But though it has been proved possible for Him to be made Man, yet if the Jews still disbelieve, let us hold this forth to them: What strange thing do we announce in saying that God was made Man, when yourselves say that Abraham received the Lord as a guest? What strange thing do we announce, when Jacob says, For I have seen God face to face, and my life is preserved ? The Lord, who ate with Abraham, ate also with us. …

XIV. “If any man says that the Son did not appear to Abraham, but the Unborn God, or a part of Him: let him be anathema.

Man , then, was thus snared by the assault of the arch-fiend, and broke his Creator’s command, and was stripped of grace and put off his confidence with God, and covered himself with the asperities of a toilsome life (for this is the meaning of the fig-leaves); and was clothed about with death, that is, mortality and the grossness of flesh (for this is what the garment of skins signifies); and was banished from Paradise by God’s just judgment, and condemned to death, and made subject to corruption. Yet, notwithstanding all this, in His pity, God, Who gave him his being, and Who in His graciousness bestowed on him a life of happiness, did not disregard man. …

104. This especially was Abraham’s praise, for he watched at the door of his tent, that no stranger by any chance might pass by. He carefully kept a lookout, so as to meet the stranger, and anticipate him, and ask him not to pass by, saying: “My lord, if I have found favour in thy sight, pass not by thy servant.” Therefore as a reward for his hospitality, he received the gift of posterity.

107. In all the duties of hospitality kindly feeling must be shown to all, but greater respect must be given to the upright. For “Whosoever receiveth a righteous man, in the name of a righteous man, shall receive a righteous man’s reward,” as the Lord has said. Such is the favour in which hospitality stands with God, that not even the draught of cold water shall fail of getting a reward. Thou seest that Abraham, in looking for guests, received God Himself to entertain. Thou seest that Lot received the angels. And how dost thou know that when thou receivest men, thou dost not receive Christ? Christ may be in the stranger that comes, for Christ is there in the person of the poor, as He Himself says: “I was in prison and thou camest to Me, I was naked and thou didst clothe Me.”.

80. The heathen king saw in the fire, together with the three Hebrew children, the form of a fourth, like as of an angel, and because he thought that this angel excelled all angels, he judged Him to be the Son of God, Whom he had not read of, but in Whom he believed. Abraham, also, saw Three, and adored One.
