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.”? When men sleep, are they then not men? Or cannot He, who can fashion the likeness of a body to signify Himself through the visions of dreamers, also fashion that same bodily creature to signify Himself to the eyes of those who are awake? Whereas His own very substance, whereby He Himself is that which He is, cannot be shown by any bodily likeness to one who sleeps, or by any bodily appearance to one who is awake; but this not of the Father only, but also of the Son and of the Holy Spirit. And certainly, as to those who are moved by the visions of waking men to believe that not the Father, but only the Son, or the Holy Spirit, appeared to the corporeal sight of men,—to omit the great extent of the sacred pages, and their manifold interpretation, such that no one of sound reason ought to affirm that the person of the Father was nowhere shown to the eyes of waking men by any corporeal appearance;—but, as I said, to omit this, what do they say of our father Abraham, who was certainly awake and ministering, when, after Scripture had premised, “The Lord appeared unto Abraham,” not one, or two, but three men appeared to him; no one of whom is said to have stood prominently above the others, no one more than the others to have shone with greater glory, or to have acted more authoritatively?
