3 Again, you are wont to reproach us with persecuting you by the help of the civil power. In regard to this, I do not draw an argument either from the demerit involved in the enormity of so great an impiety, nor from the Christian meekness moderating the severity of our measures. I take up this position: if this be a crime, why have you harshly persecuted the Maximianists by the help of judges appointed by those emperors whose spiritual birth by the gospel was due to our Church? Why have you driven them, by the din of controversy, the authority of edicts, and the violence of soldiery, from those buildings for worship which they possessed, and in which they were when they seceded from you? The wrongs endured by them in that struggle in every place are attested by the existing traces of events so recent. Documents declare the orders given. The deeds done are notorious throughout regions in which also the sacred memory of your leader Optatus is mentioned with honour.
