Dr. Moritz demonstrates a clear, thoughtful presentation on the concept of biblical separation. Most Christians might percieve the doctrine of separation with the connotation of shun. However, the emphasis behind bilbical separation is the pursuit of holiness in a believer because of a holy God. Be Ye Holy begins a primer study on this doctrine.
However, Dr. Mortiz made the book quite short on purpose to persuade the reader to go into a more in-depth study. Also, Dr. Moritz explains the origins of the New Evangelical movement and the effects of modernism upon mainstream Christianity.
I recommend this short book to anyone wanting a fair, precise view on the fundamental Scriptural doctrine of separation.
