"The Torah is neither abolished as thought it were bad or demonic, nor affirmed in the sense in which the Jews took it. It was a good thing, given deliberately by God for a specific task and a particular period of time. When the task is done and the time is up, the Torah reaches its goal, which is also the conclusion of its intended reign, not because it was a bad thing to be abolished but because it was a good thing whose job is done. In terms of the Luther-Calvin debate which has dominated discussion of this issue, we can put it like this. The Lutheran wants to maintain the sharp antithesis between law and gospel; so does Paul, but within the context of a single plan of God, and with no suggestion that the Torah is itself a bad thing. The Calvinist wants to ensure that God did not change his plan, or his mind, in the middle of history; so does Paul (that, indeed, is what Romans 9-11 is all about), but he insists that the single plan always involved a dramatic break, a cross and a resurrection written into the very fabric of history. The Messiah is the fulfilment of the long purposes of Israel's God. It was for this that Torah was given in the first place as a deliberately temporary mode of administration. In the Messiah are fulfilled the creator's paradoxical purposes for Israel and hence for the world. He is the climax of the covenant."
