The Tune My Heart Catechism has deep roots in the traditions of Christians who have gone before. It is based on historic catechisms, including the Heidelberg catechism, the Westminster catechism, Benjamin Keach’s catechism, and Charles Spurgeon’s catechism. Since it has 52 questions, it is manageable to teach children and then regularly review through the years, allowing families to focus on one question per week and progress through the catechism every year. The catechism covers the most significant doctrinal issues, broad enough so that really any evangelical Christian with any denominational or eschatological position can use it (particular denominations can supplement this with their own specific Questions and Answers). It helps teach core doctrines but also is personal, devotional, and addresses the heart.
