Obviously this does not refer to the rhetorical quality of Jesus’ discourses, but rather to the open claim that he himself is on the same exalted level as the Lawgiver—as God. The people’s “alarm” (the RSV translation unfortunately tones this down to “astonishment”) is precisely over the fact that a human being dares to speak with the authority of God. Either he is misappropriating God’s majesty—which would be terrible—or else, and this seems almost inconceivable, he really does stand on the same exalted level as God.
