Christian churches divide into about three basic types, 1) Catholic, 2) Conservative Protestant, and 3) Liberal Protestant.  There are many groups with their own unique variations in each category.

Maybe it can be said that group one lives by, "Everyone must work and do as we say", group two says, "The Bible is the only source of reliable guidance", and group three says, "No book is going to tell us what to do."

The points listed as Conservative Protestant in Appendix I and II are the best match with the Bible.  The other positions, in my opinion, are non-biblical points of view that people have taken because they don't like what the Bible says, so they make adjustments they find more pleasing to their situations.

Anyone considering a non-biblical position should first  examine the proofs for Biblical inspiration.  With a little study and an open mind, they're very convincing.

Note 1:  Many people confuse the immaculate conception with the virgin birth. The former is a Roman Catholic belief that in about 20 BC when Mary herself was conceived, she was without original sin.  The latter is a generally held belief among all conservative and most mainline Christian denominations that Mary was a virgin when Jesus was conceived about 6 BC.  Religious liberals generally consider both to be mythical concepts.
