The religious history of the fifteenth century was dominated by the Great Schism. The religious education of the laity had never occupied so high a place among the priorities of those clergy who took their duties seriously. The majority of priests capable of preaching and eager to do so effectively lived in towns, and thus their normal congregations represented only a small proportion of the total Christian population. At the beginning of the fifteenth century a ruling of the Inquisition listed the actions characteristic of a good and faithful Christian. The Catholic belongs to a complex society which cannot function without priests. Image-makers, painters and sculptors, put the resources of their talents and craft at the service of this multi-faceted religion. As people can estimate the frequency and regularity of religious practice, they can establish that the majority of the faithful did carry out the prescriptions of the Church, year in, year out.
