Peasants brought up on a tradition of superstitious magic could hardly be expected to distinguish between such ostensibly Christian rituals and the mumbled incantations of the local wizard. And so, to the discomfort of the priests, many came to regard elements of Christian devotion as simple magical spells. The Latin Mass was, after all, incomprehensible to the common people, so it already had the aspect of an occult formula. It came to be seen, like magic, as an essentially mechanical rite through which absolution was achieved by observing the correct procedures. In that case, there was no real need for faith.
