In the Foreword to DeMar's book Ruler of the Nations, John W. Whitehead notes that the book "presents a clear and well-substantiated description of the three types of government established by God-the family, the church, and the civil government-each given its own specific and limited jurisdiction". In the Editor's Introduction, Gary North points out DeMar's description of "an intellectual war going on, a war between two rival views of God, man, law and society." North says that the "book has made the meaning of theocracy clear".
