The Danger of Private Judgement
The leprosy of private judgement is the more fatal in that it is hidden....It is found in those who have a zeal for God but not according to knowledge (Rom. 10:2): they follow their errors with so much obstinacy that they will listen to no advice. They are firebrands of discord, enemies of peace, deprived of charity, puffed up with pride, full of themselves and great in their own eyes, ignorant of the justice of God and desirous of substituting their own for it.
