WHEN Fletcher finished his “Second Check to Antinomianism,” in “Three Letters” to Walter Shirley, he began a “Vindication of the Doctrine of Christian Perfection.” This, however, for a time, was laid aside; but was afterwards completed, and embodied in his “Last Check to Antinomianism.” The reason for this postponement was a somewhat sudden determination to write upon the Unitarian Controversy, which was now as prominent as the Calvinian one. A brief biographical episode will explain the matter more fully. Edward Elwall was born at Sedgley, in Staffordshire. He settled in business at Wolverhampton, where he acquired the reputation of great integrity in his dealings. He had not enjoyed the advantages of a learned education, but he possessed a serious and inquisitive turn of mind, and had good natural abilities. One of his first publications was intended to prove that the fourth commandment, appointing the _seventh_ day of the week to be observed as the Sabbath, was binding on all generations. As long as he continued in business, he constantly shut up his shop on that day, and as regularly opened it on the succeeding one. For this he was called a Jew. About the year 1714, he became distinguished as an Unitarian, and published, “A true Testimony for God and His sacred Law, being a Defence of the first Commandment of God, against all Trinitarians under Heaven.” This drew on him the resentment of the neighbouring clergy, who procured an indictment against him for heresy and blasphemy, on which he was tried at Stafford Assizes. He pleaded his own cause, and was acquitted. After this, he removed to London, and became a member of the Seventh-day Baptist Church at Mill-yard, Goodman’s Fields. Towards the end of life, he attended the meetings of the Quakers, and was sometimes permitted to speak at them. He died in London, at an advanced age, about the year 1745. Elwall’s work “against all Trinitarians under Heaven” had recently been re-published, and Fletcher was requested to answer it. Hence the following, hitherto unpublished, letter, addressed to “the Rev. Walter Sellon, at Ledsham, near Ferry-Bridge, Yorkshire.” “MADELEY, _January 7, 1772_. “MY DEAR FRIEND,—I thank you for yours. I hope Glazebrook[253] will be more moderate, on account of some rubs which his new Calvinistic zeal has procured him. “My reason for troubling you soon with an answer is to make a request. I have laid by my Third ——[254], which is a vindication of the doctrine of Christian perfection. A pamphlet (the third edition) has lately been published at Birmingham, and meets with great success. The author is E. Elwall, a Socinian Quaker, who was tried for blasphemy at Stafford, and came off with flying colours, after fully denying the Godhead of Christ, and His atonement.
