Life of Constantine

For whoever have addressed themselves with integrity of purpose to any course of action, keeping the fear of God continually before their thoughts, and preserving an unwavering faith in him, without allowing present fears or dangers to outweigh their hope of future blessings— such persons, though for a season they may have experienced painful trials, have borne their afflictions lightly, being supported by the belief of greater rewards in store for them; and their character has acquired a brighter luster in proportion to the severity of their past sufferings.

With regard, on the other hand, to those who have either dishonorably slighted the principles of justice, or refused to acknowledge the Supreme God themselves, and yet have dared to subject others who have faithfully maintained his worship to the most cruel insults and punishments; who have failed equally to recognize their own wretchedness in oppressing others on such grounds, and the happiness and blessing of those who preserved their devotion to God even in the midst of such sufferings: with regard, I say, to such men, many a time have their armies been slaughtered, many a time have they been put to flight; and their warlike preparations have ended in total ruin and defeat.
