This page directs the reader to scholarly information on the background of the Heidelberg Catechism.
For an introductory article see Professor Lyle Bierma’s Introduction to the Heidelberg Catechism on Gospel Translations (reprinted from Ligonier Ministries’ “Table Talk”) Note:
While Gospel Translations have many notable materials available freely, discernment is required. They would depart from the historic Reformed confessions on a number of points on issues relating to Baptism and the Church.
