The Evangelist does not psychoanalyze his characters. His focus remains on Jesus and on the mysterious, threatening, and threatened figure that he cuts. Jesus submits no credentials for his deeds and words; he simply speaks and acts, then allows his witnesses to draw their own conclusions (2:4-5, 10-12, 13-14, 27-28; 3:1-6). His claims for himself are circumlocutory: a physician (2:17), a bridegroom (2:19-20), the Son of Man (2:10, 28). His power (exousia) is undeniable (2:10-12; 3:5), but its source and interpretation are obscure almost to the point of inscrutability (2:9, 17b, 19-22, 25-26, 28: 3:4). Clearly, he is no hooligan: at his command withered limbs become whole (2:11-12; 3:5); by his actions the Sabbath is renewed (2:27-28) and society’s outcasts enjoy a place at the table (2:15). Feasting, not fasting, is the order of his day (2:19); it is time to glorify God (2:12). Why, then, is Jesus so troubling? What is it about the new that rips it from the old (2:21)? Why must the bridegroom be taken away (2:20)?
