Whence it appears that great mercy is shown towards them, when by the force of those very imperial laws they are in the first instance rescued against their will from that sect in which, through the teaching of lying devils, they learned those evil doctrines, so that afterwards they might be made whole in the Catholic Church, becoming accustomed to the good teaching and example which they find in it. For many of the men whom we now admire in the unity of Christ, for the pious fervour of their faith, and for their charity, give thanks to God with great joy that they are no longer in that error which led them to mistake those evil things for good,—which thanks they would not now be offering willingly, had they not first, even against their will, been severed from that impious association. And what are we to say of those who confess to us, as some do every day, that even in the olden days they had long been wishing to be Catholics; but they were living among men among whom those who wished to be Catholics could not be so through the infirmity of fear, seeing that if any one there said a single word in favour of the Catholic Church, he and his house were utterly destroyed at once? Who is mad enough to deny that it was right that assistance should have been given through the imperial decrees, that they might be delivered from so great an evil, whilst those whom they used to fear are compelled in turn to fear, and are either themselves corrected through the same terror, or, at any rate, whilst they pretend to be corrected, they abstain from further persecution of those who really are, to whom they formerly were objects of continual dread?
