Gregory the Great, on Ezek 1:28

“As the appearance of the rainbow when it is in a cloud on a rainy day: this was the appearance of the brightness round about.”

“"And I saw, and I fell upon my face." But let us recognize that the prophet, even when lifted up, could not bear this same likeness of glory. It follows: "And I saw, and I fell upon my face." What then would happen to this man if he had seen his glory as it is, when he who saw the likeness of his glory but was unable to bear it, fell? In this matter we ought to consider with great grief and contemplate with tears into what great misery and weakness we have fallen, we who cannot bear even the very good for which we were created to behold. Yet there is also another thing concerning the prophet's action that we should consider in ourselves. For the prophet, as soon as he saw the likeness of the Lord's glory, fell on his face. Since we cannot see this likeness of glory through the spirit of prophecy, we ought constantly to recognize it and carefully contemplate it in sacred scripture, in heavenly admonitions, in spiritual precepts. When we perceive something about God, we fall on our face, because we blush with shame at the evils which we remember having committed. For there a man falls where he is confounded. Hence Paul also said, as if to certain ones lying on their face: What fruit therefore did you have then in those things, of which you are now ashamed? Behold, by the generous gift of heavenly grace, we have examined the beginning of the book wrapped in mysteries in the prophet Ezekiel, and discussing the mystical words in a mortal manner, we have drawn the soaring theory of prophecy down to earth, so that what previously flew over the minds of little ones and those like me but did not elevate them, may now be read and understood by them, and may both fly and lift them up. Let us therefore give thanks to our Redeemer, who always refreshes us with spiritual nourishment, who as the living bread descended from heaven and gives life to the world. Who lives and reigns with the Father in the unity of the Holy Spirit, God, through all ages of ages. Amen.”
