Mike Higton generously alerted me to this comment by Rowan Williams in an essay from the collection to be published very soon. It seems to me that Williams is always trying think about how we can talk about God and what we might say when we are doing it:
If Jesus is constitutive for Christian language about God and for the present reality of the believer’s relation to God, in such a way that what is said, done, and suffered is strictly unintelligible without continuing reference to Jesus in a more than historically explicatory way, doctrine will be an attempt to do justice to the way in which the narrative and the continuing presence (or presence-in-absence, if you want to nuance it further) of Jesus is held actively to shape present horizons, in judgement and in grace. The disagreement is not over whether doctrinal utterances are or are not to be received uncritically, but over whether any kind of critical method can settle the legitimacy of the distinctively doctrinal enterprise itself as generally conceived by Christians, an enterprise resting as it does on the conviction, variously and often very confusedly articulated in our primary texts, that our world of speech and corporate life has been comprehensively remade, so that new conceptualities are brought to birth. Kritik can look hard at those conceptualities, with a wide variety of suspicions; but not all Wiles’s reasoned eloquence should persuade us that it is in a position to disallow the underlying unsettlement of our thought: the question, ‘What is it that is true of Jesus of Nazareth that would make some sense of the Church’s commitment to new imaginings of God and humanity and of the possibility of new relation to God and humanity?’ I believe that this is in fact the question that arises from taking with full seriousness the notion of parable which Wiles finds so attractive – an event which interrupts us and compels us to take up new positions by showing us quite unexpectedly where and what we are in respect of an unforeseen reality set down before us; something more than an extended simile. Wiles is far from insensitive to this priority of krisis over Kritik; but how can his model of doctrinal criticism allow it its proper weight?
This thought appears again and again: the narrative of Jesus AND his continuing presence (Holy Spirit? Church?) shape and reshape our 'present horizons', by judgement - bringing them to a point of krisis - and grace. Our primary texts (scripture, in other words) are very confusing, and so the task of criticism is required: but this critical task (Kritik) ought to be secondary to the more self- and world-critical task of answering to the confrontation and interruption that we find in the teaching of Jesus and the gospel itself. That's Williams' problem with Maurice Wiles, who represents the old school liberal (and most certainly not orthodox) kind of scholarship that Williams defines himself against. How can Wiles have his critical cake and eat it too? Williams is unconvinced.
However, Williams sees the parables of Jesus as giving impetus and licence to 'new imaginings' about God and God-and-us. In this way, he is 'progressivist': he might well share Peter Carnley's self-description as 'Progressive Orthodox'. Williams is committed to the expectation that there will be new things to say about God, new encounters with him, new languages about him generated.
