Defilement
It’s easy to think of the scribes and Pharisees as an impossibly self-righteous sect that neither you nor anyone you respect could ever become—like spiritual orcs. But they probably descended from Ezra, and were a reform movement like the Puritans who set out to turn the people of God back to Him. So what happened? “Thus you have made the commandment of God of no effect by your tradition”. Tradition prevailed over truth and twisted what it means to be sinful and righteous before God.
