Bede : From the fourth day until this hour, I was praying in my house at the ninth hour, and behold, a man stood before me, and so on. In Greek and in some Latin manuscripts it is written thus: From the fourth day until this hour I was fasting, and praying from the sixth hour to the ninth, and behold, a man, and so on. It was very appropriate that he who extended his prayer for three hours from the sixth to the ninth should be heard. At which time the Lord himself, whom he beseeched, prayed with outstretched hands on the cross for the salvation of the whole world. — Commentary on Acts Bede : And Cornelius said: Four days ago to this hour, I was praying in my house at the ninth hour. In Greek, it is written more fully and clearly: Four days ago to this hour, I was fasting and praying from the sixth hour until the ninth. Where it is clearly shown that four days before he spoke with Peter, he remained fasting until the ninth hour; and to make the fast acceptable to God, he prayed devoutly from the sixth hour until the ninth; hence he deserved to obtain what he sought with great persistence in fasting and prayer. — Retractions on Acts John Chrysostom : What then does Cornelius? He does not say, Why, did not the soldiers tell thee? but observe again, how humbly he speaks. For he says, "From the fourth day I was fasting until this hour; and at the ninth hour I prayed in my house, and, behold, a man stood before me in bright clothing, and said, Cornelius, thy prayer is heard, and thine alms are come up for a memorial before God." "And at the ninth hour," he says, "I was praying." It seems to me, that this man had also fixed for himself set times of a life under stricter rule, and on certain days. For this is why he says, "From the fourth day." See how great a thing prayer is! When he advanced in piety, then the Angel appears to him. "From the fourth day:" i.e. of the week; not "four days ago." For, "on the morrow Peter went away with them, and on the morrow after they entered into Caesarea:" this is one day: and the day on which the persons sent came (to Joppa) one day: and on the third (the Angel) appeared: so that there are two days after that on which (Cornelius) had been praying. "And, behold, a man stood before me in bright clothing:" he does not say, an Angel, so unassuming is he: "and said, Cornelius, thy prayer is heard, and thine alms are had in remembrance in the sight of God." — Homily on Acts 23 Oecumenius : It seems to him that the seasons of his life had become more exacting for him, and on certain days. For this reason he said, "From the fourth day." When then the angel appears to him, this is one day; and the day on which those sent from Cornelius withdrew is one; and the day on which they came is one; and on the fourth he appeared about the third hour, after which he prayed. See then the greatness of the prayer, when he committed himself to holiness; then the angel appears to him. — Commentary on Acts Oecumenius : A man, he says, and not an angel; therefore he was without form. — Commentary on Acts
