How can a Christian reject part of the Bible and still call themselves a Christian?

[vorlon13]

I don't think it's not completely unreasonable for a person who believes in some form of Christianity (for all kinds of reasons - social, personal, emotional, etc.) to believe that the Bible is not necessarily 100% accurate.  After all, we have history books all over the place that document actual historical events but are mistaken in small, and sometimes even in large part.  A person can acknowledge mistakes in the Bible and still believe in Christianity just as a person can acknowledge mistakes in a Civil War history book and still believe there was a Civil War.  I'm not saying it's logical to believe in the first place (and I don't think it has anything to do with logic), but merely that the belief in a religion doesn't necessarily require one to accept everything in that religion's texts as flawless descriptions of reality.

But if one does acknowledge that there might be flaws in a text, then that text as a whole cannot reasonably be put forth as a proof that the belief is a descriptions of reality.    Similarly, if a person does present the text as accurate - if they make the claim that it is the "Word of God - then they put themselves in the position of having to demonstrate that it is accurate.

How can the process of God divinely inspiring His word via the Bible go awry then ??
