A letter to a gentleman in Edinburgh, containing remarks upon a late apology for the Presbyterians in Scotland, who keep communion in the ordinances of the Gospel, with Mr. George Whitefield, a Priest of the Church of England; and shewing that such a practice is not justifiable by the Principles and Practice of the Church of Scotland, from the Reformation to this Day, nor by the Westminster Confession of Faith, Solemn League and Covenant. In which Letter, Mr. Whitefield's Religion, Orthodoxy, and Moral Character, are set in a proper Light, by Collections from his own printed Performances.
