How Do You Personally Decide Which Doctrines Are Biblically Sound?

Take the poll, and then come back here for discussion.

For even more discussion, hop over to my FaceBook page.

Note: I tried to word the poll in a way that would apply to all people who have ever heard of the Bible, regardless of their opinions about it. I’m not asking which doctrines you believe are true (if any), or even if you think the Bible is true. I merely want to know how you decide if a doctrine is established by the writers of the Bible.

On a second line of thought,  do you think there are any doctrines that are suggested in one or two places in the Bible, yet are not upheld by the whole Bible? I am asking this question, not only of those who do not believe in the inerrant Word, but of those who are confused by a few [seemingly] contradictory passages.

Personally, I believe there are perfectly logical answers to clear up any confusion or so-called contradictions, but we may have to lay aside some commonly-held doctrines to remove the veil of darkness that disables us from seeing what should be the clear truth of the matter.
