To me, some commentaries are better than others. I pretty much go along with you, but the biblical scholars know a lot more than I do.
So I cautiously judge and choose.
My own interpretation is skewed by my life experiences.
Obviously you are correct. My real point is that the men who write these commentaries may be excellent scholars, filled with the Holy Spirit, etc. They are still men like us, and like us they make mistakes. We are responsible for using our own judgment and intelligence. Naturally, we can’t all be biblical scholars.
That said, one test that I use is that the more a commentator tries to get away from the plain text of the Scriptures, especially on the moral issues, the less I tend to trust him on more esoteric measures, such as who gets into heaven or qualifies as a Christian, eschatology, and how our government should function.
Call me an ignorant bigot, but that’s the way i see it.
