Chapter 53: That the Barbarians kindly received the Christians
But what is the consequence of this? Why, the barbarians themselves may boast now of the contrast their conduct presents to these creel deeds; for they received and kept in gentlest captivity those who then fled from among us, and secured to them not merely safety from danger, but also the free exercise of their holy religion. And now the Roman people bear that lasting stain which the Christians, at that time driven from the Roman world, and taking refuge with the barbarians, have branded on them.
