From the above condensed account of the proceedings of the conference of 1758, it will be seen, that Wesley was exceedingly anxious, and, in fact, resolved, at all hazards, to maintain the purity of his preachers and societies. “Are our societies,” he asked, “in general as godly, and as serious, as the old Puritans? Why should they not? What means can we use to effect it?” Then follows the answer, to “enforce family discipline,” and to “closely examine the state of every soul, not only at stated times, but in every conversation.”[336] In accordance with this was a laconic letter, which, at the beginning of the year, Wesley wrote to Mr. Merryweather, of Yarm. “LONDON, _January 16, 1758_. “MY DEAR BROTHER,—No person must be allowed to preach or exhort among our people, whose life is not holy and unblamable; nor any who asserts anything contrary to the gospel which we have received. And, if he does not own his fault and amend it, he cannot be a leader any longer. “I am your affectionate brother, “JOHN WESLEY.”[337] The day after the Bristol conference closed its sittings, Wesley attended a performance of Handel’s “Messiah” in Bristol cathedral; and, on August 21, set out on a tour in Wales, from which he returned to Bristol on September 2. Here he spent a considerable time, with the Rev. John Fletcher and other preachers, in discussing the doctrine of Christian perfection, and wrote down the general propositions in which they were all agreed. On October 2, he started for London. At Bradford he met the stewards of the Wiltshire and Somersetshire societies. At Warminster, he preached in a good man’s yard, his congregation being numerous, and consisting of “saints and sinners, rich and poor, churchmen, quakers, and presbyterians.” “Some disturbance,” says he, “was expected, but there was none. The whole assembly behaved well; and, instead of curses or stones, we had many blessings as we rode through the town for Salisbury.” Strangely enough, this was Wesley’s first and last visit to the town of Warminster. Some time afterwards, however, a class was formed; and, amid the bitterest persecutions, held on its way. Men would often enter the preaching house, and remain, during the whole service, covered with their slouching hats, cursing the preacher and his friends, and even smoking vile tobacco. Sometimes they would challenge the Methodists to fight; and, at others, sing profane songs while the Methodists sang sacred ones. In one instance, they smashed the seats, and windows, and pulpit of the meeting-house in Back Street; threw John Spicer into a deep ditch; and so injured Caleb Daniel that he died soon after.[338]
