How does he expect to discover by this proposition whether He be the Son of God or not? For to fly through the air is not proper to the Divine nature, for it is not useful to any. If then any were to attempt to fly when challenged to it, he would be acting from ostentation, and would belong rather to the Devil than to God. If it is enough to a wise man to be what he is, and he has no wish to seem what he is not, how much more should the Son of God hold it not necessary to shew what He is; He of whom none can know so much as He is in Himself?
