The "Larger Catechism" is a document created by the Westminster Assembly in the 17th century. It serves as a comprehensive guide to Christian doctrine, particularly for the Presbyterian tradition. The catechism consists of a series of questions and answers that cover essential beliefs, including the nature of God, the purpose of life, and the role of the church. Designed for deeper theological understanding, the "Larger Catechism" is often used in teaching and preaching. It complements the shorter version, known as the Shorter Catechism, and is intended for those seeking a more detailed exploration of Reformed theology.
