Ante-Nicene Fathers/Volume VI/Arnobius/Adversus Gentes/Book I/Chapter VI

6. Although you allege that those wars which you speak of were excited through hatred of our religion, it would not be difficult to prove, that after the name of Christ was heard in the world, not only were they not increased, but they were even in great measure diminished by the restraining of furious passions. For since we, a numerous band of men as we are, have learned from His teaching and His laws that evil ought not to be requited with evil, that it is better to suffer wrong than to inflict it, that we should rather shed our own blood than stain our hands and our conscience with that of another, an ungrateful world is now for a long period enjoying a benefit from Christ, inasmuch as by His means the rage of savage ferocity has been softened, and has begun to withhold hostile hands from the blood of a fellow-creature. But if all without exception, who feel that they are men not in form of body but in power of reason, would lend an ear for a little to His salutary and peaceful rules, and would not, in the pride and arrogance of enlightenment, trust to their own senses rather than to His admonitions, the whole world, having turned the use of steel into more peaceful occupations, would now be living in the most placid tranquillity, and would unite in blessed harmony, maintaining inviolate the sanctity of treaties.
