Nicene and Post-Nicene Fathers, Ser. II, Vol I:
The Life of Constantine with Orations of Constantine and Eusebius.: Chapter LV

Chapter LV.—Constantine employed himself in Composition of Various Kinds to the Close of his Life.

These offenders, however, were soon over-taken by divine chastisement. To return to our emperor. He had so thoroughly trained his mind in the art of reasoning that he continued to the last to compose discourses on various subjects, to deliver frequent orations in public, and to instruct his hearers in the sacred doctrines of religion. He was also habitually engaged in legislating both on political and military questions; 3355 in short, in devising whatever might be conducive to the general welfare of the human race. It is well worthy of remark, that, very shortly before his departure, he pronounced a funeral oration before his usual auditory, in which he spoke at length on the immortality of the soul, the state of those who had persevered in a life of godliness, and the blessings which God has laid up in store for them that love him. On the other hand he made it appear by copious and conclusive arguments what the end of those will be who have pursued a contrary career, describing in vivid language the final ruin of the ungodly. His powerful testimony on these subjects seemed so far to touch the consciences of those around him, that one of the self-imagined philosophers, of whom he asked his opinion of what he had heard, bore testimony to the truth of his words, and accorded a real, though reluctant, tribute of praise to the arguments by which he had exposed the worship of a plurality of gods. By converse such as this with his friends before his death, the emperor seemed as it were to smooth and prepare the way for his transition to a happier life.
