The answer is this. The Lord did not come to make a display. He came to heal and to teach suffering men. For one who wanted to make a display the thing would have been just to appear and dazzle the beholders. But for Him Who came to heal and to teach the way was not merely to dwell here, but to put Himself at the disposal of those who needed Him, and to be manifested according as they could bear it, not vitiating the value of the Divine appearing by exceeding their capacity to receive it.

Athanasius of Alexandria
