The Westminster Shorter Catechism is unrivaled as a concise and faithful summary of the central teachings of Scripture. For decades G. I. Williamson's study manuals on the Shorter Catechism have served as invaluable tools for instructing young and old in the Reformed system of doctrine. Now newly typeset in one volume, this illustrated manual offers clear and helpful exposition of each of the 107 questions in the Shorter Catechism. Each lesson includes Scripture proofs, as well as questions for review or discussion, making this a useful aid for individual study or group instruction.
