One of the Moravians themselves, who had been the physician in one of their religious houses, and had also been a preacher among them both at home and abroad, and who, with his wife, still attended their services, informed Wesley of his own knowledge of sensual abominations practised by the brethren and sisters at Leeds and Bedford, which, though referred to in Wesley’s Journal, we shall not pollute our pages by printing. No wonder, after Wesley had committed the man’s statement to writing, and had submitted it to him for his own correction, he should exclaim in a burst of sorrowful indignation, “Was there ever so melancholy an account? and what is human nature! How low are they fallen, who were once burning and shining lights, spreading blessings wherever they came!” Wesley has oft been blamed for speaking far too harshly of his old Moravian friends; but those who blame him are either ignorant of facts like those alluded to above, or they wickedly wink at their existence. Moravianism in England, in 1751, had become, to a great extent, a luscious morsel of antinomian poison; and it was a painful knowledge of this distressing fact, which led Wesley to adopt the course he did. One pamphlet, published at the close of 1750, has not been mentioned, though there is little doubt that Wesley was its author. His name does not appear; but that was not unusual, for many of his tracts and pamphlets were printed without his name, or with his initials only. The preface is dated “London, October 2, 1750,” though Wesley then had retired for a month to Kingswood, for the purpose of writing books. The style is his to a nicety, and the most incredulous will find it difficult to doubt that Wesley was the writer. The pamphlet was not published in his own edition of his collected works in 1771; but that is not conclusive evidence against its authenticity, for other pamphlets were similarly omitted, as, for instance, his “Extract of Zinzendorf’s Discourses,” seventy-eight pages, and his Zinzendorf’s Hymns, twelve pages. Its title is as follows: “The Contents of a Folio History of the Moravians, or United Brethren, printed in 1749, and privately printed and sold under the title of ‘_Acta Fratrum Unitatis in Anglia_,’ with suitable remarks. Humbly addressed to the Pious of every Protestant Denomination in Europe and America. By a Lover of the Light. London: 1750.” 12mo, 60 pages. On the title page there is the following text:— “While they promise them liberty, they themselves are the servants of corruption.” Rightly to understand the merits of this peculiar and now extremely scarce publication, it is necessary to look back upon the Moravian history of the previous five years.
