It’s a strange thing that even though the Heidelberg Catechism is one of our confessions, so little has been written on it. Sure, we hear sermons on it each Sunday, but where are the commentaries digging deeper into some of the theological issues? We have had books of catechism sermons published (e.g. Stam, Wieske) but, so far as I can tell, there has never been a true commentary from our circles.

While R. Scott Clark isn’t Canadian Reformed, he is a minister in the United Reformed Churches, sister churches of the CanRC. He recently retired from teaching at Westminster Seminary California. He is well-known for his website, the Heidelblog and its associated enterprises.

This commentary is a massive achievement – over 900 pages of exposition and interaction with the Catechism. It explains the historical background of each Lord’s Day. Clark is especially concerned to give authority to the voice of Zacharias Ursinus, the principal author of the Catechism. Read more»
