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

[Lek]

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.

I'll go along with that.
