What these people need to get through their thick sculls is that Dan is a Catholic school teacher.Dan is not a priest.I don't see him as being a preachy sort of guy.Yes he has conversations about the bible with people,but its not so much like he's giving a sermon,he's trying to have an intelligent conversation about something.Amber and whats her face last year were waaay more into throwing God out there,which I don't really hear Dan do.He lied about one thing to a few people and he genuinely feels bad about it.April and Michelle claim they are Catholic and I don't see either of them living life as one.Jerry,I don't know what denomination he is,but I doubt they condone his words and actions.
As far as attending church goes,if you only show up on holidays you can call yourself what you want,but the Catholic church doesn't consider you a Catholic.That is to say you should not be taking communion(you would need to go to confession first),they will not baptize your baby,nor can you get married there.Maybe Dan doesn't go to church EVERY Sunday,he must go regularly.I never heard him say he didn't,only that he doesn't attend every Sunday.
