Of players who have become Christians.

And of them also it must be sought that if anyone wishes to come to the grace of Christianity from any ludicrous art (ludicra arte) and to remain free of that stain, it be not lawful for anyone to induce him or compel him to return to the performance of the same things again.

Notes.
