Heidelberg Catechism, Lord's Day 29

Lord's Day 29 of the Heidelberg Catechism presents the Reformed doctrine of justification by faith alone, emphasizing that believers are declared righteous through Christ's work rather than their own merit or works. This catechetical exposition serves as a foundational teaching tool for Protestant Reformed instruction in the central doctrine of salvation. The resource represents one of the most influential Reformed confessional documents emerging from the 16th-century Reformation.
