What is Catechism?

Author: Ursinus, Zacharias (1534-1583)

Zacharias Ursinus was one of the primary writers of the Heidelberg Catechism, one of the most important documents of Reformed churches across the world. As well as the Catechism itself, Ursinus authored commentary on the Catechism as well as various theological essays. In What is Catechism?, he defines the word “catechism,” prescribes the proper applications catechisms, and defends the importance of catechization generally. The theologian supports his claims with both Scripture and appeals to the history of the Church and its traditions. Ursinus provides modern readers with a succinct, fascinating look into the formation and reasoning behind Protestant catechisms.
