B. B. Warfield remarked almost a century ago that the Westminster Larger Catechism has received sparse attention in comparison to the Confession and Shorter Catechism. In fact, apart from a reprint of the 1731 commentary on the Larger Catechism by Thomas Ridgley, and a chapter on the theology of the Larger Catechism by Morton Smith in volume one of The Westminster Confession Into the 21st Century, no other significant study of the Westminster Larger Catechism remains in print today. In light of this, students of Reformed theology should welcome Vos’s contribution. Vos offers excellent commentary, laying bare the basic structure of the catechism. The first main section (questions 5-90) explains “what men ought to believe concerning God” and the second main section (questions 91-196) discusses “the duty which God requires of man.” These two basic divisions structure the theology contained in the larger catechism and furnish a useful pedagogical framework for Sunday school classes and Bible studies. - Jeff Waddington - Westminster Bookstore Staff
