Context: Those among them that have not received our religion do not fright any from it, and use none ill that goes over to it, so that all the while I was there one man was only punished on this occasion. He being newly baptised did, notwithstanding all that we could say to the contrary, dispute publicly concerning the Christian religion, with more zeal than discretion, and with so much heat, that he not only preferred our worship to theirs, but condemned all their rites as profane, and cried out against all that adhered to them as impious and sacrilegious persons, that were to be damned to everlasting burnings. Upon his having frequently preached in this manner he was seized, and after trial he was condemned to banishment, not for having disparaged their religion, but for his inflaming the people to sedition; for this is one of their most ancient laws, that no man ought to be punished for his religion.
                                    
“A man must be orthodox upon most things, or he will never even have time to preach his own heresy.”
