Territorial Spirits

A fellow alma mater Peter Wagner wrote a book: Territorial Spirits. One may think that a spirit broods over one's local Church alone, or that a pattern of problems is unique to one's local Church. Without necessarily endorsing Wagner, what ails one's Church may be territorial, in that one has networks of people whose influence reaches into more than one Church. I am not speaking of the spirit of the age, but rather of territorial phenomena.
