Also he that is not sent to preach this fundamental article, but taketh it upon him of his private authority, though he be a witness, and consequently a martyr, either primary of Christ, or secondary of His apostles, disciples, or their successors; yet is he not obliged to suffer death for that cause; because being not called thereto, it is not required at his hands; nor ought he to complain if he loseth the reward he expecteth from those that never set him on work. None therefore can be a martyr, neither of the first nor second degree, that have not a warrant to preach Christ come in the flesh; that is to say, none but such as are sent to the conversion of infidels. For no man is a witness to him that already believeth, and therefore needs no witness; but to them that deny, or doubt, or have not heard it. Christ sent His apostles and His seventy disciples, with authority to preach; He sent not all that believed. And He sent them to unbelievers; “I send you,” saith He ( Matt. 10:16), “as sheep amongst wolves”; not as sheep to other sheep.
