On Commentaries

I trust none of them unrservedly, and I expect nowhere to find perfection. All must be read with caution. They are good helps but they are not infallible. They are useful assistants, but they are not the pillar and cloud of fire. I advise my younger readers to remember that. Use your judgment prayerfully and diligently. Use commentaries, but be slave to none. Call no man master.
