Ursinus (Zacharias Ursinus)

Zacharias Ursinus was a 16th-century German theologian best known for co-authoring the Heidelberg Catechism, a foundational Christian teaching document created in 1563. The catechism is a systematic summary of Christian beliefs used for education and instruction within the Reformed tradition. Ursinus aimed to present God's teachings in a clear, accessible way, emphasizing faith, scripture, and the importance of personal devotion. His work remains influential in Reformed churches today, serving as a guide for understanding core doctrines and fostering spiritual growth.
