I guess what got me was the fact that the books in our Bibles were chosen by priests, which ones were included, which ones weren't. Also that some Bibles have books that are not in the current Protestant canon and that some books in our canon references books that were excluded from the canon. Kind of casts doubt on the whole idea that it is the infallible word of God.
Not to mention how many sects and even individuals in the same sect bicker and argue over seemingly minor details of the Bible.
Most Christians are quick to say that they must follow the word of God as closely as possible but at the same time most don't even know what exactly are they following other than 'what the pastor says.' Either that or they go to their specific religious literature that their pastor (or other church leader) finds agreeable. That's not much different than what witnesses do, eh? "If it did not come from JW.ORG you better not read it for it may be apostate," said my Mother-In-Law to my wife one day.
Add to that the fact that most Christians (and that includes Jehovah's Witnesses) do not care about doctrine and it makes you wonder why should anyone care. Especially when the true answer cannot be found (we do not have the original writings anymore) and most every believer relies on some religious leader to supply it. I truly think that they (the religious leaders) will be judged most harshly due to (if for no other reason) their position of power and influence.
