7.  Moreover, that you may be sure that this is He who was seen of Moses, hear Paul’s testimony, when he says, For they all drank of a spiritual rock that followed them; and the rock was Christ 1 Cor. x. 4..  And again:  By faith Moses forsook Egypt Heb. xi. 27., and shortly after he says, accounting the reproach of Christ greater riches than the treasures in Egypt Heb. xi. 26.  Quoting from memory Cyril mistakes the order of the two sentences..  This Moses says to Him, Shew me Thyself.  Thou seest that the Prophets also in those times saw the Christ, that is, as far as each was able.  Shew me Thyself, that I may see Thee with understanding Ex. xxxiii. 13.  Cyril means that even before His Incarnation Christ was seen as far as was possible by Prophets such as Moses.  This view was held by many of the Fathers before Cyril.  See Justin M. (Tryph. § 56 ff.); Tertull. (adv. Praxean, § 16); Euseb. (Demonstr. Evang. V. 13–16)..  But He saith, There shall no man see My face, and live Ex. xxxiii. 20..  For this reason then, because no man could see the face of the Godhead and live, He took on Him the face of human nature, that we might see this and live.  And yet when He wished to shew even that with a little majesty, when His face did shine as the sun Matt. xvii. 2., the disciples fell down affrighted.  If then His bodily countenance, shining not in the full power of Him that wrought, but according to the capacity of the Disciples, affrighted them, so that even thus they could not bear it, how could any man gaze upon the majesty of the Godhead?  ‘A great thing,’ saith the Lord, ‘thou desirest, O Moses:  and I approve thine insatiable desire, and I will do this thing Ex. xxxiii. 17.  Gr. λόγον, “word,” in imitation of the Hebrew idiom. for thee, but according as thou art able.  Behold, I will put thee in the clift of the rock Ex. xxxiii. 22.:  for as being little, thou shalt lodge in a little space.’
