But I digress. Why did I enjoy reading from the book of Hebrews so much? Because it makes claims, and backs them up with evidence. I should clarify by this that I don't mean scientific or historical claims, but about points of doctrine. That said, every claim is backed up by at least one direct quotation from the Old Testament. I'd like to quote the entire first chapter, but I'm not certain how copyright applies to translations. A brief look at the NIV website suggests I'm not providing enough original comment on this post to be able to reprint a full chapter, so I'll just invite you to read it here.
I have frequently heard said things to the effect that the Christian merit of a church is identical to the extent to which it relies on the Bible. I think that this understates the role of critical reason - the Bible can be completely infallible, and yet we can still be prone to misunderstand it - but there is certainly a great deal of truth to that statement. So it is a delight to see theology being done by direct reference to scripture, as a divine example as to how we should do our own biblical analysis.
