  In the moral Enquiry Hume is more explicit about what he takes to be the errors of Christian (or, more cautiously, Roman Catholic) moralists. Not only have they elevated craven humility to the status of a virtue, which he hints in the Treatise is a mistake, but they also favor penance, fasting, and other “monkish virtues” that are in fact disapproved by all reasonable folk for their uselessness and disagreeableness, and so are in fact vices.
