It is possible for those who have come back again after repentance to shine with much lustre, and oftentimes more than those who have never fallen at all, I have demonstrated from the divine writings. Thus at least both the publicans and the harlots inherit the kingdom of Heaven, thus many of the last are placed before the first.
-St. John Chrysostom, AN EXHORTATION TO THEODORE AFTER HIS FALL, 4th Century


For the nature of a fast is such, that it does not suffice to deliver those who practise it, unless it be done according to a suitable law. "For the wrestler," it is said, "is not crowned unless he strive lawfully."
-St. John Chrysostom, Homily III, 4th Century


The Publican fasted not; and yet he was accepted in preference to him who had fasted; in order that thou mayest learn that fasting is unprofitable, except all other duties follow with it.
-St. John Chrysostom, Homily III, 4th Century
