Ecclesiastical History

When the illustrious emperor Theodosius had heard of the emperor's doings and what the tyrant Maximus had written to him he wrote to the fugitive youth to this effect: You must not be astonished if to you has come panic and to your enemy victory; for you have been fighting against piety, and he on its side. You abandoned it, and are running away naked. He in its panoply is getting the mastery of you stripped bare of it, for He who has given us the law of true religion is ever on its side.

So wrote Theodosius when he was yet afar off; but when he had heard of Valentinian's flight, and had come to his aid, and saw him an exile, taking refuge in his own empire, his first thought was to give succour to his soul, drive out the intruding pestilence of impiety, and win him back to the true religion of his fathers. Then he bade him be of good cheer and marched against the tyrant. He gave the lad his empire again without loss of blood and slew Maximus. For he felt that he should be guilty of wrong and should violate the terms of his treaty with Gratianus were he not to take vengeance on those who had caused his ally's death.
