11 “How is it you do not understand that I did not speak to you concerning bread?—but to beware of the leaven of the Pharisees and Sadducees.” 12 Then they understood that He did not tell them to beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.” (Matthew 16:11–12, NKJV)
Jesus warned against the doctrine of the Pharisees and Sadducees. The Pharisees bound the traditions of the elders as if they were the law of God (Mark 7:1-13). The Sadducees went to the other extreme, denying the Scriptures with their teaching of no resurrection, no angel and no spirit (Matthew 22:23-33; Acts 23:8). Currently, some categorize doctrine as “primary essentials,” “secondary essentials,” primary non-essentials,” and “secondary non-essentials” (“Doctrine Grid,” Matt Slick, carm.org/doctrine-grid). We have yet to discover such graduations of doctrine identified and defined in the inspired Scriptures (2 Timothy 3:16-17). Then, there are those who would convince us doctrine is entirely non-essential to salvation, and to hold doctrine as essential is to incite division amongst believers (“The Gospel/Doctrine Distinction, Part Two,” Tom Roberts, truthmagazine.com). Why would Jesus warn against their doctrine, if doctrine is secondary, and not essential for God’s approval? In fact, “the doctrine of Christ” is essential for fellowship with God and His people (2 John 9-11). The doctrine of the Pharisees and Sadducees is still at work today.
