Amess method in this book is not an analysis of the Catechism itself. Rather, he chooses a particular text of Scripture that supports the main thoughts for a given Lords Day. While the exposition is directly from the Bible, Amess doctrinal conclusions interact with the corresponding Questions and Answers of the Heidelberg Catechism.

Joel R. Beeke and Todd M. Resters introduction provides valuable background on Ames and his work. Resters fresh translation from the Latin opens several avenues of interest for modern day English readers. Historians of 16th and 17th century thought will value the critical English translation of a much neglected text, and the fact that it demonstrates the interaction between English Puritanism and the Dutch Further Reformation.

Reformed pastors will also take interest in this, as it provides another important resource on a classic doctrinal standard.
