How do you know thats the holy spirit Nambo? You're letting the context interpret the experience for you. If you went to a Hindu temple and felt good did you experience the presence of Shiva? If you went out into the woods and felt good did you experience the presence of Pan? I've been to many a religious service and sometimes I feel good but that proves nothing about any kind of spirit in-dwelling the place.
And Finkelstein, why assume Satan takes any part in the decisions made by past or present leadership? They found an easy way to trick gullible people into giving them money, constructing their buildings, getting their name out into the public, etc. That's all it takes, that's the only explanation necessary. Why invoke some supernatural being?
