“Martyrs are Witnesses, . . . no other Religion was ever propagated by Witnesses, who had seen, and heard, and been every way conversant in what they witnessed concerning the Principles of their Religion; no Religion besides was ever preach’d by Men, who, after an unalterable Constancy under all Kinds of Sufferings, at last died for asserting it, when they must of necessity have known, whether it were true or false, and therefore certainly knew it to be true, or else they would never have suffer’d and died in that Manner for it.”
— Robert Jenkin (1656-1727)
