There is no doubt that pagans accept the idea of territorial spirits as a reality.
The following article shows how well organised the concept of 'territorial spirits' is in pagan culture. In contrast, biblical teaching exposes it as a web of lies spun by the devil in order to keep people in bondage, being no more than a demonically projected virtual reality.
The problem now is that some Christians accept the notion of 'territorial spirits' as readily as pagans, the only difference being that they believe that such 'spirits' should be confronted through authoritative prayer and commands issued 'in the Spirit'. Those who believe in 'territorial spirits' may well take the information in this article as a justification for their position, whereas those who reject the idea of 'territorial spirits' will see the article as proof of the pagan origin of this idea.
