This book, while dated, gives a fabulous exegesis on spiritually abusive systems. I highly recommend this to anyone who left a cult-ish background, or any PKs (Preacher's/Pastor's Kids) out there.

There is a section on healing, as well, which has quite sound exegesis. Some of the stories aren't quite for every situation (the spiritual abuse I endured was much more subtle) but an excellent read even if you THINK you might have endured spiritual abuse.

This book made me grateful for my parents (who were NOT spiritual abusers or bought into it, thank God). Their commitment to each other, to me, and to God were the reasons we all (somehow) remained sane. They gave me the gift of being able to think for myself in the midst of a bunch of CRAP. ;)
