Next year (2013) marks the 450th anniversary of the Heidelberg Catechism. This Protestant document was written in Heidelberg in 1563 on behalf of Frederick III, Elector Palatine and spread over the world when it was approved by the Synod of Dort in 1619. A new volume is being released next March to commemorate this important event in church history—Power of Faith: 450 Years of the Heidelberg Catechism, edited by Karla Apperloo-Boersma, Herman J. Selderhuis. See flyer from publisher the Vandenhoeck & Ruprecht here. In this 440 page hardcover book, respected specialists in their fields present how the Heidelberg Catechism spread and influenced culture, education and ecclesiastical life. In addition to the text, over 250 pictures illustrate the contributions making an attractive volume for display. This work will include the following contribution from Michael A. G. Haykin and Steve Weaver "To 'concenter with the most orthodox divines': Hercules Collins and his An Orthodox Catechism—a slice of the reception history of the Heidelberg Catechism."
