It only takes a minute to form a tradition. Otherwise, we would have to face ourselves or our Master more directly. A tradition is like a callous, in that sense. As a callous makes it harder to feel, a tradition makes it harder to hear. You don’t need to hear or obey God if he no longer needs to speak. Then you can replace his word with your own ideas. The drive constantly pulls on us to control our own consciences and lives instead of letting God do it. Like the Pharisees, we have already acquired our own reward, and there is nothing left for Jesus to give us. For we believe we are some variety of saint, and he only came for sinners.
