NOTES for Mat 23:13-39
The most terrible thing is that the higher a person's calling, the more tragic and painful his falling away, his unbelief, becomes. The Pharisees were religious teachers of God's people, guardians of tradition, law, and Scripture. Jerusalem is "the city of the great King," but it is precisely there that Christ dies. The Jews are the chosen people, "God's own," yet "He came to His own, and His own did not receive Him."
We Christians are also a people chosen by God, children of Abraham by faith, guardians of the Gospel Tradition. Therefore we too walk along the edge of the abyss; we too are in the risk group. At any moment our piety can turn into hypocrisy, conviction in faith into a sense of our own rightness, respect for traditions into legalism. How can we avoid "the leaven of the Pharisees" and still remain God's people? How can we preserve faithfulness to the Gospel without losing Christ?
