The rising influence of lay piety is particularly marked upon the Mariological controversies of the late medieval period. Two rival positions developed: the maculist position, which held that Mary was subject to original sin, in common with every other human being; and the immaculist position, which held that contrary view that Mary was in some way preserved from original sin, and was thus to be considered sinless. The maculist position was regarded as firmly established within the High Scholasticism of the thirteenth century. The veneration of the Virgin within popular piety, however, proved to have an enormously creative power that initially challenged, and subsequently triumphed over, the academic objections raised against it by university theologians.
