Lactantius

“ How much more is it befitting, that man, who is united with man both in the interchange of language and in communion of feeling, should spare man, and love him! For this is justice.
But since wisdom has been given to man alone, that he may understand God, and this alone makes the difference between man and the dumb animals, justice itself is bound up in two duties. He owes the one to God as to a father, the other to man as to a brother; for we are produced by the same God. ”

“ But the former belongs to wisdom, the latter to virtue; and justice comprises both. If, therefore, it is evident that man is born to justice, it is necessary that the just man should be subject to evils, that he may exercise the virtue with which he is endued. For virtue is the enduring of evils. He will avoid pleasures as an evil: he will despise riches, because they are frail ”

“ Therefore it has been deservedly and rightly said, that wisdom is the knowledge of divine and human affairs. For it is right that we should know what we owe to God, and what to man; namely, to God religion, to man affection. ”
