Calvin's thought moved on another plane. He was distinguished among the Reformers for his zeal to restore again the conditions which had ruled in the Church of the first three centuries. This had been a favourite idea with Lefèvre,[117] who had taught it to Farel, Gerard Roussel, and the other members of the "group of Meaux." Calvin may have received it from Roussel; but there is no need to suppose that it did not come to him quite independently. He had studied the Fathers of the first three centuries more diligently than any of his contemporaries. He recognised as none of them did that the Holy Supper of the Lord was the centre of the religious life of the Church, and the apex and crown of her worship. He saw how careful the Church of the first three centuries had been to protect the sacredness of the simple yet profound rite; and that it had done so by preventing the approach of all unworthy communicants. Discipline was the nerve of the early Church, and excommunication was the nerve of discipline; and Calvin wished to introduce both. Moreover, he knew that in the early Church it belonged to the membership and to the ministry to exercise discipline and to pronounce excommunication. He desired to reintroduce all these distinctive features of the Church of the first three centuries--weekly communion, discipline and excommunication exercised by the pastorate and the members. He recognised that when the people had been accustomed to come to the Lord's Table only once or twice in the year, it was impossible to introduce weekly communion all at once. But he insisted that the warnings of St. Paul about unworthy communicants were so weighty that notorious sinners ought to be prevented from approaching the Holy Supper, and that the obstinately impenitent should be excommunicated. This and this alone was the distinctive thing about Calvin's proposals; this was the new conception which he introduced.
