Fletcher was added to the number of Lady Huntingdon's chaplains. It is almost unnecessary to say that this was not an "appointment" in the strict sense of the word, but that he preached from time to time to the fashionable congregations that assembled at Lady Huntingdon's house at Chelsea. These assemblies have often been described. They included the most distinguished men and women of the day. Chesterfield, Bolingbroke, Horace Walpole and others, bear witness to the fashion which prevailed. To listen to Whitefield in Lady Huntingdon's drawing-room became a recognised diversion for society, and the most cynical and worldly were found side by side with the serious and devout. Undoubtedly some "who came to scoff remained to pray." Amongst the women of rank who heard the gospel in this way several were converted, and became earnest and faithful witnesses for Christ; but the hindrances to deep and lasting results were very great, and we are inclined to think that this particular phase of the Evangelical Revival was by no means among its most fruitful or important developments. The ignorance and brutality of the crowds to whom Wesley and Whitefield preached, presented no such resistance to the gospel as the vanity and finished worldliness of the drawing-room congregations. An instance will suffice. A lady who had been invited by Lady Huntingdon replied in the following terms: "I thank your ladyship for the information concerning the Methodist preachers. Their doctrines are most repulsive, and strongly tinctured with impertinence and disrespect towards their superiors, in perpetually endeavouring to level all ranks and do away with all distinctions. It is monstrous to be told you have a heart as sinful as the common wretches that crawl on the earth. This is highly offensive and insulting, and I cannot but wonder that your ladyship should relish any sentiments so much at variance with high rank and good breeding."[3]
There is no record of the impression made by Fletcher upon these fashionable congregations. Meanwhile he was engaged in a work probably more congenial to him, viz. preaching to the French prisoners, a number of whom were settled at Tunbridge. After a few months this came to an end; he was forbidden by the Bishop of London to continue his ministrations. There was something "irregular" in them, it would appear. Wesley wrote afterwards, "If I had known this at the time, King George should have known it; and I believe he would have given the bishop little thanks."
