Giving particular attention to the duties of my office, I wrote several tracts for the use of my congregation, as two _Catechisms_, an _Address to masters of families on the subject of family prayer_, a _discourse on the Lord’s Supper_, and on _Church discipline_, and _Institutes of Natural and Revealed religion_. Here I formed three classes of Catechumens, and took great pleasure in instructing them in the principles of religion. In this respect I hope my example has been of use in other congregations. The first of my controversial treatises was written here in reply to some angry remarks on my discourse on the Lord’s Supper by Mr. Venn, a clergyman in the neighbourhood. I also wrote remarks on Dr. _Balguy’s sermon on Church authority_, and on some paragraphs in Judge _Blackstone’s Commentaries_ relating to the dissenters. To the two former no reply was made; but to the last the judge replied in a small pamphlet; on which I addressed a letter to him in the St. James’s Chronicle. This controversy led me to print another pamphlet, entitled _The Principles and Conduct of the Dissenters with respect to the civil and ecclesiastical constitution of this country_. With the encouragement of Dr. Price and Dr. Kippis, I also wrote an _Address to Protestant Dissenters as such_; but without my name. Several of these pamphlets having been animadverted upon by an anonymous acquaintance, who thought I had laid too much stress on the principles of the Dissenters, I wrote a defence of my conduct in _Letters addressed to him_. The methodists being very numerous in Leeds, and many of the lower sort of my own hearers listening to them, I wrote an _Appeal to the serious professors of Christianity_, an _Illustration of particular texts_, and republished the _Trial of Elwall_, all in the cheapest manner possible. Those small tracts had a great effect in establishing my hearers in liberal principles of religion, and in a short time had a far more extensive influence than I could have imagined. By this time more than thirty thousand copies of the Appeal have been dispersed. Besides these theoretical and controversial pieces, I wrote while I was at Leeds my _Essay on Government_ mentioned before, my _English Grammar_ enlarged, a _familiar introduction to the study of electricity_, a _treatise on perspective_, and my _Chart of History_, and also some anonymous pieces in favour of civil liberty during the persecution of Mr. Wilkes, the principal of which was _An Address to Dissenters on the subject of the difference with America_, which I wrote at the request of Dr. Franklin, and Dr. Fothergil.
