For the life of me, I don't understand why the "I'm Catholic but" people don't leave the Roman Catholic church and join any one of 35,000 different Protestant groups, probably 20,000 of which don't care at all what you believe. Joe Biden, Nancy Pelosi and John Kerry give Catholicism a bad name. Catholics have a central authority, they cover more scripture in a month of daily masses than other churches do in a year, and they have a Pope, some better than others. They have up to the minute documents written by scholars on marriage, abortion, education, serving the poor, government, war, immigration, euthanasia, etc. and a catechism so fat you can use it as a door stop. They have beautiful cathedrals and great music.
Anything goes in Protestant churches, and you can leave because of the sermons or the potlucks and walk down the street and join one more to your liking. You can choose from hard rock or old hymns and liturgy for your worship style. You can be your own pope and decide what the Bible says about marriage and abortion and no one can contradict you because the Holy Spirit told you.
I just wish someone would ask them to leave and stop calling themselves Catholics. Many churches are looking for them and their wealth and would welcome them. http://www.ncregister.com/daily-news/joe-bidens-unfaithful-catholic-witness-on-marriage/
