Edward observed a contrary policy with regard to the church: he seems to have been the first Christian prince that passed a statute of mortmain; and prevented by law the clergy from making new acquisitions of lands, which by the ecclesiastical canons they were forever prohibited from alienating. The opposition between his maxims with regard to the nobility and to the ecclesiastics, leads us to conjecture, that it was only by chance he passed the beneficial statute of mortmain, and that his sole object was to maintain the number of knights’ fees, and to prevent the superiors from being defrauded of the profits of wardship, marriage, livery, and other emoluments arising from the feudal tenures. This is indeed, the reason assigned in the statute itself, and appears to have been his real object in enacting it. The author of the Annals of Waverley ascribes this act chiefly to the king’s anxiety for maintaining the military force of the kingdom but adds, that he was mistaken in his purpose; for that the Amalekites were overcome more by the prayers of Moses than by the sword of the Israelites.[*] The statute of mortmain was often evaded afterwards by the invention of “uses.” Edward was active in restraining the usurpations of the church; and excepting his ardor for crusades, which adhered to him during his whole life, seems in other respects to have been little infected with superstition, the vice chiefly of weak minds. But the passion for crusades was really in that age the passion for glory. As the pope now felt himself somewhat more restrained in his former practice of pillaging the several churches in Europe by laying impositions upon them, he permitted the generals of particular orders, who resided at Rome, to levy taxes on the convents subjected to their jurisdiction; and Edward was obliged to enact a law against this new abuse. It was also become a practice of the court of Rome to provide successors to benefices before they became vacant: Edward found it likewise necessary to prevent by law this species of injustice.
