I don't know, Padre. A lot or Catholics I know think it is the only Christian religion. They are proud to be Catholic and refuse to be anything else. My first wife was one of these. She was going to be married to a Catholic or it was a deal breaker. They are indoctrinated at parochial schools and on Sunday mornings. Mass is so different from a Protestant service.My second son was marrying a Catholic girl...since he was Baptist and had been divorced, he was told he would have to go through an annulment, yada, yada, yada. His fiance' -- now wife said that was ridiculous, so they get up and walk out. Married in a protestant church, eventually joined a Presbyterian church where she is now a deacon. The RC needs to recognize that they are no longer the bully in the room in the USA. Quite frankly, if not for the Hispanic immigration they would have serious problems in the USA.
Protestants jump from church to church depending on the issues of the day. Our church has lost a lot of members to Baptist churches recently over the issue of whether or not to allow gay pastors.
