I would be sickened if I had elderly parents who gave money to some religion.
They truly believe they are scoring points with God. (Treasures in heaven.)
Fortunately, though they were certainly not "rich", they were not in the financial situation that it caused them to do without anything they needed or desired. However, they were always frugal and practical and saved some money vs. earning a lot of money. They have since become disgusted with the handling of finances by the Org/Cong (ridiculous Assm Hall fees and expensive remodels of a KHall only 10 years old) and thus they only give modestly. Plus, since The End(TM) did not come "on schedule", they could see their remaining funds diminishing and the New World not here as promised.
