     To Protestants, therefore, whose common rule and touchstone is the Scripture, nothing can with more conscience, more equity, nothing more Protestantly can be permitted, than a free and lawful debate at all times by writing, conference, or disputation of what opinion soever, disputable by Scripture ; concluding that no man in religion is properly a heretic at this day, but he who maintains traditions or opinions not probable by Scripture, who for aught I know is the Papist only ; he the only heretic who counts all heretics but himself.
