of sins to be confessed-sins of thought, the sources of sinful actions, brought to light by the confessor's questions; and different satisfactions were imposed at the discretion of the priest corresponding to the sins confessed. This led to the construction of penitentiaries containing lists of penances supposed to be proportionate to the sins. In many cases the penances were very severe and extended over a long course of years. From the seventh century there arose a system of commutations of penances. A penance of several years' practice of fasting might be commuted into saying so many prayers or psalms, giving prescribed alms or even into a money fine-and in this last case the analogy of the Wergeld of the Germanic codes was frequently followed. This new custom commonly took the form that anyone who visited a prescribed church on a day that was named and gave a contribution to the funds of the church had his penance shortened by one-seventh, one-third, one-half, as the case might be. This was in every case a commutation of a penance which had been imposed according to the regulations of the Church (relaxatlo de injuncta poenitentia). This power of commuting imposed penance was usually supposed to be in the hands of Bishops, and was used by them to provide funds for the building of their great churches. But priests for a time also thought themselves entitled to follow the episcopal example; and did so until the great abuse of the system made the Church insist that the power should be strictly kept in episcopal hands. Thus the real origin of Indulgences is to be found in the relaxation by the Church of a portion of the ecclesiastical penalties imposed according to regular custom.
Three conceptions, however, combined to effect a series of changes in the character of Indulgences, all of which were in operation in the beginning of the thirteenth century. These were the formulation of the thought of a Treasury of merits, the change of the institution of penance into the Sacrament of Penance, and the distinction between attrition and contrition. The two former led to the belief that the Pope alone had the power to grant Indulgences-the treasure needed a guardian to prevent its being squandered; and, when Indulgences were judged to be extra-sacramental and a matter of jurisdiction and not of Orders, they belonged to the Pope, whose jurisdiction was supreme.
The conception of a Treasury of merits was first formulated by Alexander of Hales in the thirteenth century, and his ideas were accepted and stated with more precision by the great Schoolmen who followed him Starting with the existing practice in the Church that some penances, such for example as pilgrimages, might be performed vicariously, and bringing together the conceptions that all the faithful are one community, that the good deeds of all the members are the common property of all, that sinners may benefit by the good deeds of their fellows, that the sacrifice of Christ is sufficient to wipe out the sins of all, theologians gradually formulated the doctrine that there was a common storehouse
