Boston's work is the most complete set of references ever written on the Westminster Shorter Catechism. Regarding the Shorter Catechism, A.F. Mitchell states
The Shorter Catechism is the "king of catechisms" for its great power of expression, combining logical forcefulness with conciseness. Boston's exposition is unrivaled; there is nothing like it. Here we have the cream of Puritan catechisms married to the cream of clear Puritan exposition. This is probably Boston's most important work. A set that will meet numerous needs, from use in family worship, Christian education, and personal study, to sermon preparation - and to help resolve debated issues in the presbytery. A unique set of books that will serve your family for generations.
