I admit at the beginning that 'popular religion,' 'demotic religion,' the pieties of the common folk, tends to sink to the lowest common denominator, be it in syncretizing saints with old, half-forgotten pagan godlings, or in preferring the nasal whine and the revivalist shoutin' to solid sense and learning, regarding intellect as positively inimical to the workings of the Holy Ghost. But it is in American religious life, especially Protestant American religious life, that things bottom out completely.
