It was no less characteristic of the indefatigable energy which formed another and a better side of his nature, that immediately after this change he started on a pilgrimage to Herrnhut, the head-quarters of Moravianism, in order that he might study to the best advantage what he now regarded as the purest type of a Christian church. He returned objecting to many things, but more than ever convinced of his new doctrine, and more than ever resolved to spend his life in diffusing it. In the course of 1738 the chief elements of the movement were already formed. Whitefield had returned from Georgia. Charles Wesley had begun to preach the doctrine with extraordinary effect to the criminals in Newgate and from every pulpit into which he was admitted. Methodist societies had already sprung up under Moravian influence. The design of each was to be a church within a church, a seed-plot of a more fervent piety, the centre of a stricter discipline and a more energetic propagandism, than existed in religious communities at large. In these societies the old Christian custom of love-feasts was revived. The members sometimes passed almost the whole night in the most passionate devotions, and voluntarily submitted to a spiritual tyranny that could hardly be surpassed in a Catholic monastery. They were to meet every week, to make an open and particular confession of every frailty, to submit to be cross-examined on all their thoughts, words, and deeds. The following, among others, were the questions asked at every meeting: "What known sin have you committed since our last meeting? What temptations have you met with? How were you delivered? What have you thought, said, or done of which you doubt whether it be sin or not? Have you nothing you desire to keep secret?" Such rules could only have been accepted under the influence of an overpowering religious enthusiasm, and there was much truth in the judgment which the elder brother of John Wesley passed upon them in 1739. "Their societies," he wrote to their mother, "are sufficient to dissolve all other societies but their own. Will any man of common-sense or spirit suffer any domestic to be in a band engaged to relate to five or ten people anything without reserve that concerns the person's conscience, how much soever it may concern the family? Ought any married person to be there unless husband and wife be there together?"
