“Meanwhile, the constant pressure of Islam was becoming an increasing danger for Europe, and Hungary was in the forefront of the fight; yet this did not awaken the Catholic countries to see the folly of destroying a barrier between them and their most dangerous foe, and the Pope wrote (1325) to the Ban of Bosnia: “Knowing that thou art a faithful son of the Church, we therefore charge thee to exterminate the heretics in thy dominions, and to render aid and assistance unto Fabian, our Inquisitor, forasmuch as a large multitude of heretics from many and divers parts collected, have flowed together into the Principality of Bosnia, trusting there to sow their obscene errors and to dwell there in safety. These men, imbued with the cunning of the Old Fiend, and armed with the venom of their falseness, corrupt the minds of Catholics by outward show of simplicity and lying assumption of the name of Christians; their speech crawleth like a crab, and they creep in with humility, but in secret they kill, and are wolves in sheep’s clothing, covering their bestial fury as a means whereby they may deceive the simple sheep of Christ.”
