[T]he reason Paul was ‘doing theology’ was not that he happened to have the kind of brain that delighted in playing with and rearranging large, complex abstract ideas. He was doing theology because the life of God’s people depended on it, depended on his doing it initially for them, then as soon as possible with them, and then on them being able to go on doing it for themselves. All Paul’s theology is thus pastoral theology, not in the sense of an unsystematic therapeutic model which concentrates on meeting the felt needs of the ‘client’, but in the sense that the shepherd needs to feed the flock with clean food and water, and keep a sharp eye out for wolves. For that, pastoral theology needs to be crystal clear, thought out and presented in a way that teaches others to think as well. That, too, is part of the point: Christian theology, for Paul, was not just about what you know, but about how you know. And, just as the Christian worldview compels people to think in a new way, because otherwise the worldview itself is unstable, so Christian theology remains both a corporate task, one in which the church as a whole has to engage, rather than being spoon-fed by one or two high-octane teachers, and also an incomplete task, because each generation needs to become mature in its thinking, which wouldn’t happen if Paul, Athanasius, Aquinas, Luther, Barth or anyone else had closed off the questions with answers that could then simply be looked up. The ‘authority’ of Paul did not consist in his providing lots of correct answers to puzzling questions. That would have left his converts, and subsequent generations, with no work to do on the questions he had answered, and no starting-point for the ones he didn’t. They would have remained radically and residually immature. Give someone a thought, and you help them for a day; teach someone to think, and you transform them for life. Paul’s authority consisted in his setting up a particular framework and posing a specific challenge. Living as Messiah-people demanded, he would have said, that people work within that framework and wrestle with that challenge.
