[10] The Bull was issued June 15, 1520. It specified forty-one
propositions out of Luther's works which it condemned as heretical,
scandalous, and offensive to pious ears. It forbade all persons to
read his writings, upon pain of excommunication. Such as had any of
his books in their possession were commanded to burn them. He himself,
if he did not publicly recant his errors and burn his books within
sixty days, was pronounced an obstinate heretic, excommunicated and
delivered over to Satan. And it enjoined upon all secular princes,
under pain of incurring the same censure, to seize his person and
deliver him up to be punished as his crimes deserved; that is to be
burnt as a heretic.
