From this point onward, the slow movement of new ideas may for a time be conveniently traced on two general lines--one that of the philosophic discussion in the schools, reinforced by Saracen influences, the other that of partially rationalistic and democratic heresy among the common people, by way first of contagion from the East. The latter was on the whole as influential for sane thought as the former, apart from such ecclesiastical freethinking as that of Berengar of Tours and Roscelin (Rousselin), Canon of Compiègne. Berengar (c. 1050) was led by moral reflection [1258] to doubt the priestly miracle of the Eucharist, and thenceforth he entered into a stormy controversy on the subject, in the course of which he twice recanted under bodily fear, but passionately returned to his original positions. Fundamentally sincere, and indignantly resentful of the gross superstition prevailing in the Church, he struck fiercely in his writings at Popes Leo IX and Nicholas II and Archbishop Lanfranc, [1259] all of whom had opposed him. At length, after much strife, he threw up the contest, spending the latter part of his long life in seclusion; Pope Gregory VII, who was personally friendly to him, having finally shielded him from persecution. It seems clear that, though accused, with others of his school, of rejecting certain of the gospel miracles, [1260] he never became a disbeliever; his very polemic testifying to the warmth of his belief on his own lines. His teaching, however, which went far by reason of the vividness of his style, doubtless had the effect of promoting not only the rationalistic-Christian view of the Eucharist, [1261] but a criticism which went further, inasmuch as his opponents forced on the bystanders the question as to what reality there was in the Christian creed if his view were true. [1262] All such influences, however, were but slight in total mass compared with the overwhelming weight of the economic interest of the priesthood; and not till the Reformation was Berengar's doctrine accepted by a single organized sect. The orthodox doctrine, in fact, was all-essential to the Catholic Church. Given the daily miracle of the "real presence," the Church had a vital hold on the Christian world, and the priest was above all lay rivalry. Seeing as much, the Council of the Lateran (1059) met the new criticism by establishing the technical doctrine of the real presence for the first time as an article of faith; and as such it will doubtless stand while there is a Catholic priesthood. Berengar's original view must have been shared by thousands; but no Catholic carried on his propaganda. The question had become one of life and death.
