Augustine of Hippo

(ubi sup.) Matthew therefore intended to state summarily all that passed between the centurion and the Lord, which was indeed done through others, with the view of commending his faith; as the Lord spoke, I have not found so great faith in Israel. Luke, on the other hand, has narrated the whole as it was done, that so we might be obliged to understand in what sense Matthew, who could not err, meant that the centurion himself came to Christ, namely, in a figurative sense through faith.
