“It is of faith that the Pope has the right of deposing heretical and rebel kings. Monarchs so deposed by the Pope are converted into notorious tyrants, and may be killed by the first who can reach them.
“If the public cause cannot meet with its defense in the death of a tyrant, it is lawful for the first who arrives, to assassinate him.”
[Defensio Didei, Jesuit Suarez, Book VI. C 4, Nos. 13, 14]
