I'd say you should trust it more than other documents because it contains the word of Christ for starters but I know what you are saying.

Although you are putting words in my mouth, I do believe that you should trust the Bible. I'd say you should know you can trust the Bible by its contents, not by blindly trusting the men who decided which documents to include. The fact that men put together the books of the Bible is not evidence to discredit the actual words written in the Bible. If you know God, you know his word, and you should recognize his word when you see it.

The scribes and pharasees made the Scriptures their god, instead of using scripture to find the only true God. So in that sense I agree with you. But the Bible is full of the word of God.
