What is the Heidelberg Catechism?
The Heidelberg Catechism is one of the most beloved Reformed confessional documents, written in 1563 in Heidelberg, Germany. Commissioned by Elector Frederick III, it was primarily authored by Zacharias Ursinus and Caspar Olevianus.
The catechism consists of 129 questions and answers divided into 52 Lord's Days for weekly instruction throughout the year. It teaches the Christian faith through three main themes:
- Misery (Questions 1-11) - Our sin and need for salvation
- Deliverance (Questions 12-85) - Redemption through Christ
- Gratitude (Questions 86-129) - Living the Christian life
The catechism begins with the famous Question 1: "What is your only comfort in life and in death?" The answer beautifully expresses assurance in Christ: "That I am not my own, but belong—body and soul, in life and in death—to my faithful Savior, Jesus Christ."
