So absolutely nothing does it avail to be near Christ, if not being near Him by faith .... Signifying therefore that not the assault of the wind, but his want of faith had wrought his overthrow, He said, "Wherefore did you doubt, O you of little faith?"
-St. John Chrysostom, Homily 50 on Matthew 14, 4th Century


So that if his faith had not been weak, he would have stood easily against the wind also. And for this reason, you see, even when He had caught hold of Him, He suffers the wind to blow, showing that no hurt comes thereby, when faith is steadfast.
-St. John Chrysostom, Homily 50 on Matthew 14, 4th Century
