Tell me about it. Foursquare have a lot to answer for in all this. For years the leader of the Potters House,Wayman Mitchell ridiculed and mocked Forsquare while he was in it and flouted many of their laws. From what I heard he never really properly qualified from bible college anyway yet they gave him a total of three churches.
In my book Foursquare were spineless in dealing with him at the start and naive all the way through. While I don't blame them directly for the damage done by Wayman's sect over the years I do think they have been guilty of extreme neglect and abdication of responsibility in all this.
At least half the lighthouse church had the sense to leave. From what I know of what Wayman likes to call 'partnering together' it would not surprise me if Prescott benefitted significantly from the lighthouse church.
