Heidelberg Catechism

Zacharias Ursinus and Caspar Olevianus (1534-1583 / 1536-1587)

Commissioned by Elector Frederick III of the Palatinate, the Heidelberg Catechism covers sin, salvation, and gratitude across 129 questions organized into 52 Lord's Days. It opens with one of the most beloved questions in Christian history: what is your only comfort in life and death?
