Samuel Wesley was in great doubt respecting them, and, in a letter dated September 3, 1739, asks:—“Did these agitations ever begin during the use of any collects of the Church? or during the preaching of any sermon that had before been preached within consecrated walls without effect? or during the inculcating any other doctrine besides that of your new birth?”[303] The Rev. Ralph Erskine wrote to Wesley thus: “Some of the instances you give seem to be exemplified, in the outward manner, by the cases of Paul and the gaoler, as also Peter’s hearers (Acts ii.). The last instance you give of some struggling as in the agonies of death, is to me somewhat more inexplicable, if it do not resemble the child of whom it is said, that ‘when he was yet a coming, the devil threw him down and tore him.’ I make no question, Satan, so far as he gets power, may exert himself on such occasions, partly to mar and hinder the beginning of the good work, in the persons that are touched with the sharp arrows of conviction; and partly also to prevent the success of the gospel on others. However, the merciful issue of these conflicts, in the conversion of the persons thus affected, is the main thing.” Erskine proceeds to state, that they have something, in Scotland, analogous to what had occurred in Bristol. Sometimes a whole congregation, in a flood of tears, would cry out at once, so as to drown the voice of the minister.[304] The Rev. William Hales, D.D., in his “Methodism Inspected,” accounts for these paroxysms on “natural grounds; the sympathetic nature of all violent emotions being well known to those who have studied the physical and moral constitution of man.” Southey writes:— “A powerful doctrine, preached with passionate sincerity, produced a powerful effect upon weak minds, ardent feelings, and disordered fancies. There are passions which are as infectious as the plague, and fear itself is not more so than fanaticism. When once these bodily affections were declared to be the throes of the new birth, a free licence was proclaimed for every kind of extravagance; and when the preacher encouraged them to throw off all restraint, and abandon themselves before the congregation to these mixed sensations of mind and body, the consequences were what might be anticipated.” Southey forgets that “powerful doctrine” was preached, with as much “passionate sincerity,” by Whitefield and by Charles Wesley, as by Wesley himself; but without the same effects. Besides, it is untrue that Wesley ever “encouraged” the affected people “to abandon themselves to these mixed sensations of mind and body.” The Rev. R. Watson writes:—
