Over at Carla's blog awhile back, there was a question posed about loving the Scriptures too much--and putting them in the place of loving Christ. I didn't care for the wording of that question, because I think it obscured the real issue.
If we use a biblical definition of love, I don't think you can say that folks love the Scriptures too much. If you really love the Scriptures, you'll love Christ, too.
But if we ask "can we make the Bible an idol," then we've got a question worth consdering.
The answer is "yes," and here are some ways people do it.
1) When we elevate any one translation to be true Scripture, and decry all others as false. This is exactly what the King James Only folks have done.
A correct understanding of Scripture recognizes that all translations are just that, translations, and are good to the extent they are faithful to the Hebrew & Greek originals. That's not to say there isn't a place to debate methods of translation, but just to recognize that no translation is completely perfect and no faithful translation (even if we disagree with how it was done) is completely bad, either. (There are some bad translations, but that is a separate issue).
To be sure, I have strong opinions about what type of translation to use; but I am concerned that the current debate over the TNIV may be on its way to crossing this line.
2) Relating to the Word in a mystical or superstitious way. Here, I have in mind making the Bible an object of veneration. It is the Word of God, but that does not make it a sacred object. (Interestingly, my pastor suggested that I might be doing this very thing when I ask folks in church to "please stand for the reading of God's Word.")
3) Focusing on the letter vs. the spirit. It's this last one I'd like to spend a minute on.
This is the heart of the issue between Jesus and the Pharisees. They thought they knew the Scripture so well, but Christ pointed out over and over that they didn't know it at all, because at the heart of Scripture is the heart of God. And if we don't have that heart, Scripture is a closed book to us. It is truly worth nothing more than an idol.
It's one thing if I point out to a brother that he is in error; it's another thing altogether to assert that I am more righteous than he based on that fact. Any time we come away from the Scripture feeling self-righteous instead of humble, I think we have mishandled Scripture, and we may be making it an idol.
But while I agree that a legalistic approach to the Scriptures will eventually lead to this error, I disagree with those who go a step further and assert that someone who advocates orthodox belief is automatically legalistic. To be dogmatic about one's beliefs is not the same thing as being a Pharisee--there's also the matter of the heart. And at center of every Pharisee's heart there exists, not a love of God, but a love of self.
That's why I don't think we can love the Scriptures too much--we can't love the Scriptures unless we love God. I don't think those who were zealous for the letter of the law (along with their own rules), while ignoring the "weightier matters," can be rightly characterized as "loving the Scriptures," any more than it can be rightly said that a martyr for Islam truly loved God.
