The setting up of churches is BIG business, firstly the money is tax free, no property taxes. The priests have to earn a living, they are given hand books as to how to raise money , all in the name of God. To be a successful preacher, you have to know how to manipulate the congregation , it's no different than a car salesman.
Except that you will actually get a car from a car salesman. Preachers con you into selling you something you have to die first to receive. And if after you die and don't get that promise, it will be too late to utilize the lemon law.
