According to Lt. Col. Dave Grossman (Ret.), expert on terrorism and security:
"This is absolutely, without a doubt, head-and-shoulders, the best thing ever written on the subject of church safety. It should be "required reading" for every pastor in America... and around the world! … I believe that this book deserves to sit on the bookshelf of every pastor, minister, priest, or chaplain…This is a vital and essential resource for any church leader who is concerned about the safety and well being of their flock in these violent times…So don't just read this book. Study it and apply it. And have no doubt that we can save lives by doing so.
Robert Martin, Vice President of Gavin de Becker & Associates, threat assessment expert and one of the developers of MOSAIC, the most advanced instrument to determine the level of dangerousness says that: "[Wolves Among The Sheep]is very ambitious and very well done. It packs a lot of information in a small space. Good job." The Rt. Rev. John-David Schofield, former Anglican Bishop to the Diocese of San Joaquin
"So many works on church safety are solely from the military or law enforcement perspective. Here is a book that provides the reader not only with that crucial information, but goes further—supplying a vital theological rationale and deeply spiritual approach to protecting our congregations, as well as offering an understanding of those who wish to do us harm. I heartily recommend this book to every church leader and to anyone concerned with the matter of protecting the flock of Christ."
