Cyril of Jerusalem

Moses says to him, "Show me yourself." You see that then also the prophets saw Christ, that is, in the measure each was able. "Show me yourself, that I may see you clearly." But he said, "No one sees me and still lives." Therefore, because no one could see the face of the Godhead and live, he assumed the face of human nature, that seeing this we might live. Yet when he wished to show even this with a little majesty, at the time when "his face shone as the sun," the disciples fell to the earth terrified. His bodily countenance shined, not according to the full power of him who wrought it but in the measure the disciples could bear. Now if this terrified them and even thus they could not bear it, how could anyone gaze upon the majesty of the Godhead? It is a great thing which you desire, O Moses, the Lord says; and I approve your insatiable longing and "this word will I do" for you, but according to your capacity. "Behold, I will set you in the hollow of the rock";10 for as you are small, you will lodge in a small place.
