Annotations to the Heidelberg Catechism

John A. Hawthorne in Reformed Theological Journal: . . . The individual Christian would find it a constructive way to employ part of the Sabbath day by working through the lesson that is set for each Lord’s Day. No one can study this volume without increasing his knowledge of truth and being made to worship and adore the God of all grace. This book will help every minister in the instruction of his people, both young and not so young, every parent in the task of catechizing and is commended to every Christian for personal study.
