His care for his people found expression in many ways that watchful love suggested, or their necessities seemed to call for. During his occasional absences from home he addressed pastoral letters to his flock filled with Christian exhortations and counsels. The following are extracts: "_Oct., 1765._ "I beg you will not neglect the assembling of yourselves together, and when you meet in society, be neither backward nor forward to speak. Let every one esteem himself the meanest in the company, and be glad to sit at the feet of the lowest.... I had not time to finish this letter yesterday, being called upon to preach in a market town in the neighbourhood.... A gentleman churchwarden would hinder my getting into the pulpit, and, in order to do this, cursed and swore, and took another gentleman by the collar in the middle of the church. Notwithstanding his rage, I preached. May the Lord raise in power what was sown in weakness!" "_Sept., 1766._ "When I was in London I endeavoured to make the most of my time, that is to say, to hear, receive, and practise the word. Accordingly I went to Mr. Whitefield's tabernacle, and heard him give his society a most excellent exhortation upon love. He began by observing, that 'when St. John was old, and past walking and preaching, he would not forsake the assembling himself with the brethren, as the manner of too many is, upon little or no pretence at all. On the contrary, he got himself carried to their meeting, and, with his last thread of voice, preached to them his final sermon, consisting of this one sentence, "My little children, love one another."' I wish, I pray, I earnestly beseech you to follow that evangelical, apostolical advice.... Bear with one another's infirmities, and do not easily cast off any one; no, not for sin, except it be obstinately persisted in." From unpublished manuscripts of Fletcher we find that in the latter part of the year 1764 he was engaged in a somewhat remarkable controversy within his own parish. His opponent was a Mrs. Anne Darby, a member of the Society of Friends, and the subjects discussed included the Athanasian Creed, the doctrine of the Trinity, the Sacraments, and the Christian Ministry. His account of its origin is as follows: "On Thursday, November 22nd, 1764, Mrs. Darby, a female teacher among the people called Quakers, came into a house where the Vicar of Madeley was instructing his parishioners. He had given previous notice of his design to answer the objections made by dissenters and infidels against the Church of England; and he happened at her coming to defend the doctrine of the blessed Trinity, as contained in Athanasius's Creed.
