I am beginning a new series going through our confession of faith, but I began with a sermon entitled "Unleavened Theology" in which we discussed Matthew 16:5-12 and how the Scriptures must be the foundation of our doctrine. My main point was that regardless of whether we add to Scripture, as the Pharisees tended to do, or take away from Scripture, as the Sadducees tended to do, in both cases we were "teaching as doctrine the commandments of men."
