From "Isabel: Episode #2.6"
Your kingdom is a threat to Christendom. Border with infidels, refuge of Jews, infected by false converts.
Fernando de Aragón
Don't worry for the converts. The Queen gave Friar Hernando an evangelizing mission we trust in.
But in Rome it is not understood this big reticence to establish the Holy Office of the Inquisition. In neighboring kingdoms they make good use of it.
