This book presents a clear explanation of the main topics of the Reformed faith. Written in the catechetical style of question and answers, the book is noted for its succinctness and ample references to Scripture. The forty brief chapters are characterized by careful doctrinal distinctions, and each one concludes with a question or two asking what the particular subject means for the faith and spiritual reflection of the reader. For today's readers, it is both an ideal representation of the Dutch Further Reformation's attention to doctrine and piety, as well as an invitation to carry on that spiritual legacy.
