This picture, I believe, makes very good sense historically. Jesus' critique of his contemporaries was critique from within; his summons was not to abandon Judaism and try something else, but to become the true, returned-from-exile people of the one true God. He aimed to be the means of God's reconstitution of Israel. He would call into being the true, returned-from-exile Israel. He would challenge, and deal with, the evil that had infected Israel itself. He would be the means of Israel's God returning to Zion. He was, in short, announcing the kingdom of God: not the simple revolutionary message of the hard-liners, but the doubly revolutionary message of a kingdom that would overturn all other agendas, including the revolutionary one. He was a prophet, announcing and inaugurating the kingdom, summoning followers, warning of disaster, promising vindication, clashing symbolically with other agendas, implicitly claiming messiahship, and anticipating a showdown. He was, in other words, a thoroughly credible first-century Jew.
