Yeah, I understand all of this. But despite that a lot of people claim to hold a particular religious affiliation and predicate huge portions of their lives around it (even those who rarely attend church and aren't getting their dogma from a particular preacher). I'm saying that I truly do not know what is meant by "I am a Lutheran" or "I am a Catholic" (or literally any other sect or religion) when it is said by people who don't know what their sect believes.
