Probably the best place to get a catechism for your children is through your local church. However, lacking that, Luther’s Small Catechism provides for an understanding of the essentials of biblical Christianity, based on the authority and inerrancy of God’s Word, for all Protestant and evangelical Christians. The notes and explanations added provide helpful commentary for the layman. This is the catechism I learned as a child, which has grounded me in biblical authority and the doctrines of Christianity, and the catechism we used with our children. Martin Luther was a brilliant theologian whose nailing of 95 Theses on the chapel door in Wittenburg, Germany on October 31, 1517 lit a bonfire under the Reformation movement.
