What are the Small and Large Catechism?
Martin Luther realized early on how desperately ignorant the laity and clergy of his day were when it came to even the most basic truths of the Christian faith. Around 1530, he produced two small handbooks to help pastors and the heads of families teach the faith.
The Small Catechism and the Large Catechism are organized around six topics: the Ten Commandments, the Apostles' Creed, the Lord’s Prayer, Holy Baptism, Confession, and the Sacrament of the Altar. So universally accepted were these magnificent doctrinal summaries by Luther, that they were included as part of the Book of Concord.
