The Rock Whence We Are Hewn is comprised of various pamphlets and booklets written very early in the history of the Protestant Reformed Churches–between 1919 and 1940. The authors are two men whom God used in forming these churches–Herman Hoeksema and Henry Danhof. All the writings explain and defend the great doctrines of the Reformed faith that were fundamental to the founding of the Protestant Reformed Churches–covenant, predestination, particular grace, and antithesis. These writings therefore were used to establish these churches in the very beginning of their history. The contents of the book are their foundational writings.

The title of the book is taken from Isaiah 51:1: Hearken to me, ye that follow after righteousness, ye that seek the Lord: look unto the rock whence ye are hewn, and to the hole of the pit whence ye are digged. In this figurative way the prophet called the people of Israel to look to their origins. This title calls the members of the Protestant Reformed Churches, including the ministers and other officebearers, and especially the younger generation, to find in the book the doctrinal truths that are of fundamental importance to the Protestant Reformed Churches still today. By the work of the Spirit these doctrines, confessed, defended, and explained in the writings in this book, are the source of the churches–the rock whence they were hewn.
