The Westminster Shorter Catechism is a summary of Christian doctrine created in the 17th century by the Westminster Assembly. It consists of 107 questions and answers designed to teach the core beliefs of the Reformed Christian faith, particularly for children and new believers. The catechism covers topics such as the nature of God, the purpose of humanity, and the means of salvation. This catechism is widely used in Presbyterian and other Reformed churches as a tool for instruction and spiritual growth. It emphasizes the importance of understanding Scripture and encourages believers to reflect on their faith through concise, memorable teachings.
