In a few days Mr. Clark found himself in London, and located at a cheap and retired boarding house in a pious Methodist family. He now sought acquaintance with several of the more intelligent class of Mr. Wesley’s preachers, told them his trials and convictions of duty, and solicited advice. He was directed to the publications of Mr. Wesley, and also those of Rev. John Fletcher, of Madeley, and by reading and conversations with the venerable John Wesley, who treated him with great kindness, he obtained full and clear views of the doctrines they taught, the discipline they enforced, and their reasons for separate action from the Church of England. We have no facts to narrate particulars of the extent of Mr. Clark’s studies, nor how long he remained in the vicinity of Moorfields. His interviews with the venerable founder of Methodism, then in the 85th year of his age, were frequent, and as he thought highly instructive. And though in a few years he found reasons to withdraw from the society he founded and the creed and discipline he adopted, he often referred to him in his preaching and private conversations as the “great and good Mr. Wesley;” and he would state his views on various points with accuracy and in kind and courteous language. He also became acquainted with the writings and peculiar views of the noted German Bengel, or, as his name was given in Latin, _Bengelius_, and imbibed some of his peculiar notions. Those especially relating to the millennium found in Bengel’s exposition of the Book of Revelation, were often given by Father Clark. Bengel figured up the periods, and taught that the forty-two months, or twelve hundred and sixty days, expired in 1810, and the Millennium would commence in 1836. The Millennium, in the sense Father Clark understood it, was not the _personal_, but the more gracious and glorious reign of Christ on earth as Mediator and Saviour. On this topic he would dwell with a holy ecstacy, while his great modesty and humility led him to express himself as uttering the opinions of a man merely. He never attempted to make proselytes to speculations or opinions, but to Christ and entire submission to him.
