The Individual Can Judge in Matters of Heresy

“The opinion that only the Church authorities are able to judge in matters of heresy, and that we cannot know if someone is a heretic by the application of human reason without a pronouncement of Church authority, is patently absurd, since it is by the application of human reason to the matters of faith that ecclesiastical judges reach their conclusions in heresy cases and pronounce judgment.”
