Since the church had itself broken off the fetters which had previously bound them to the traditional faith of the Catholic church, the Leonists had gone too far upon the path of evangelical freedom to be satisfied with any such terms. Innocent now renewed the ban against them at the Fourth Lateran Council of A.D. 1215. Of the later life and work of the founder we know with certainty only this, that he made extensive journeys in the interests of his cause. Even during his lifetime (he died probably about A.D. 1217) the members (_socii_) of the society (_Societas Valdesiana_) founded by him had spread themselves in great numbers over the whole of the south of France, the east of Spain, the north of Italy, and the south of Germany, and had even crossed the Channel into England. They were named, in accordance with their fundamental principle, as well as from the starting point of their apostolic mission, _Pauperes de Lugduno_ or _Leonistæ_=from Lyons, also from the covering of their feet, _Sabatati_; but they styled themselves among one another _fratres_ and _sorores_, and their adherents among the people _amici_ and _amicæ_; while the Catholic polemical writers, who for a similar class among the Cathari had employed the distinctive terms _Perfecti_ and _Credentes_, made use of these designations in treating of the Waldensians. The latter continue “in the world,” that is, in the exercise of their family duties, and the discharge of civil obligations, and all the positions and entanglements connected therewith; while the former devoted themselves to a celibate life, to absolute poverty, to incessant preaching from place to place, and to unconditional refusal of all oathtaking, and a literal acceptance of all the precepts of the Sermon on the Mount, involving the rejection of any sort of fixed residence, and on the basis of Luke x. 7, 8, any handiwork that would earn for them the necessaries of life. They had their own _ministri_ for the administration of the sacraments; but these were elected only _ad tempus_, namely once a year, simply for the discharge of that duty. At the head of the whole community down to his death stood the founder himself. He led the entire movement, received new members into the _societas_, and chose and ordained the _ministri_.--The two most important sources for the primitive history of the Waldensian movement, mutually supplementing one another, are, the _Chronicon Laudunense_ of an unnamed canon of Laon in the _Mon. Germ. Scrr._ xxvi. 447, and the tract _De Septem Donis Spir. S._ of the inquisitor Stephen de Borbone, who died A.D. 1261, which is
