John Chrysostom
What then does Cornelius do? He did not say, “Did the soldiers not tell you?” But see how meekly and humbly he speaks.
“At the ninth hour,” he says, “I was praying.” What does this mean? It seems to me that he had appointed hours for pious exercises, and on certain days as well. Therefore he said, “four days ago.”
See how great prayer is. When he gave himself to pious activity, then the angel appeared to him.
This was the first day. When the messengers departed, there was another day. When they were returning, there was another. On the fourth, Peter arrived.
Thus this was the second day on which Cornelius was giving himself to prayer.
“A man stood before me in bright clothing.” He does not call him an angel. So far is he from pride.
