MacArthur on Theological Orthodoxy (Right Doctrine) and Pharisaism
“The Pharisees were in no sense guilty of an undue emphasis on theological orthodoxy. If anything, their problem was the opposite. They weren’t careful enough in seeking to understand the Scriptures. In fact, they set Scripture aside in favor of their own rote traditions. Tradition, not theology, was their downfall. If they had stuck to Scripture and built their theology on that alone, they would not have fallen into error.
Jesus confronted the Pharisees for their pride, their spiritual blindness, their legalism, their want of compassion, their love of power and recognition, and their lack of knowledge about the Word of God. At no time did He rebuke them for overemphasizing “theological correctness.” — John MacArthur —
