Exterminate the Christians!
From
The following is an exact translation of the doctrine of the Church of Rome as taught today in all Roman Catholic seminaries, colleges and universities, through the Summa Theologica of Thomas Aquinas, vol. iv., p. 90:
"Though heretics (Protestants) must not be tolerated because they deserve it, we must bear with them till, by the second admonition, they may be brought back to the faith of the church. But those who, after a second admonition, remain obstinate to their errors, must not only be excommunicated, but they must be delivered to the secular power to be EXTERMINATED."
