Watson, Thomas, 1620-1686 Body of Divinity (Carlisle, PA: The Banner of Truth Trust, 1965, 1890), EEBO.
"The first book published by the Trust, this has been one of the best sellers and consistently the most useful and influential of our publications . . . It deals with the foremost doctrinal and experimental truths of the Christian faith . . . It is based on the Westminster Assembly's Shorter Catechism, in which the main principles of Christianity that lie scattered in the Scriptures are brought together and set forth in the form of question and answer. This catechism is unsurpassed for its `terse exactitutde of definition' and `logical elaboration' of the fundamentals. . . . Watson conveys his thorough doctrinal and experimental knowledge of the truth in such an original, concise, pithy, pungent, racy, rich, and illustrative style that he is rightly regarded as the most readable of the Puritans." -- Publisher's Annotation
"As an introduction to Puritan theology, as a short and sweet course in Christian doctrine, as devotional reading, and as a preacher's gold-mine, Watson's work can hardly be praised too highly." -- J.I. Packer.
"Contains Watson's exposition of the Westminster Shorter Catechism, excluding the Lord's Prayer and the Ten Commandments." -- GCB
