The more things change....
I know a lot of protestant clergy who charge for special services, like say marriages and funerals. I don't think it's at all right to expect a fee for Baptisms, but fees for what you might call "individual services" are not a phenomenon confined to Catholics. I think it's far more a Mexican thing.
If you read my post to which you replied you will have noticed that I was writing about Catholics, including clergy, providing services to migrant workers (it wasn't a situation where we were concerned with who was legal and who wasn't) at no charge. So are you saying that we were NOT representative of Catholicism, that we were unusually charitable -- for Catholics that is?
