that land of Bosnia is homeland of heretics for a long time

"Often we have, in fact, with great sorrow listened, and from a credible source, that land of Bosnia is homeland of heretics for long time, where they also abandoned the church, the clergy is eradicated, they are treading the christian sanctities, the cross is not respected, moreover, there is no sacrament of baptism, etc." 

Letter of Pope John XXII to the croatian ruler Mladin Subic, calling him to go to war against Bosnian heretics, written in 1319
