WOW!
I wonder if Joe Biden, Kerry and Pelosi actually tithe to the Catholic church?
LOL! Most Catholics don't know from tithing! I once saw a description of modern Catholics as having deep pockets, but short arms. The culture of the Church is an immigrant one; many of the large, lovely cathedrals in urban areas were built by immigrants in the mid 19th to early 20th centuries. They didn't have a lot of money, but they gave as much as they could in treasure and talent to build them.
Their grandchildren and great-grandchildren, on the other hand, are NOT poor, but they still have the same attitudes as their forefathers, that they don't need to give money, because the more wealthy people will do that. They don't realize that THEY are those wealthy people now, and should be supporting their Parishes and schools.
