Large Catechism

Martin Luther's 'Large Catechism,' published in April 1529, is a foundational text for Christian education, particularly aimed at clergymen. It is structured into five parts: The Ten Commandments, The Apostles' Creed, The Lord's Prayer, Holy Baptism, and The Sacrament of the Altar. This work was later included in The Book of Concord in 1580, solidifying its significance in Lutheran doctrine and teaching.
