An explicatory catechism; or, An explanation of the assembly's shorter catechism: Wherein all the answers in the assembly's catechism are taken abroad in under-questions and answers, the truths explained, and proved by reason and scripture; several cases of conscience resolved; some chief controversies in religion stated, with arguments against divers errors: useful to be read in private families, after examination in the catechism itself, for the more clear and thorough understanding of what is therein learned. By Thomas Vincent, sometime minister of Maudline-Milk-Street, in London.
