Again J-Roc.......
I think it would be up to Daddy Warbucks what he wants to do with his money and his tithe. In the hypothetical case you mention if he does what is normally done by most of the evangelical christian world, he would pay 10% and the church and the pastor would be the lucky participant as long as Daddy stayed there.
Really .... what and who determines who is or isn't worth whatever amount of $$$. It's not whether the pastor is worth it or worthy of it. It boils down to the fact that Daddy W needs to tithe. Someone(s) will be the fortunate recipient of that.
And again .... who REALLY is 'worth' or worthy of that amount of money? If I was the pastor I'd feel unworthy but very very blessed!
