A sermon is a form that yields a certain kind of meaning in the same way that, say, a sonnet is a form that deals with a certain kind of meaning that has to do with putting things in relation to each other, allowing for the fact of complexity reversal, such things. Sermons are, at their best, excursions into difficulty that are addressed to people who come there in order to hear that. The attention of the congregation is a major part of the attention that the pastor gives to his or her utterance. It's very exceptional. I don't know anyone who doesn't enjoy a good sermon. People who are completely nonreligious know a good sermon when they hear one.
One of the reasons that I think that a sermon is a valuable thing now and so impressive when you do hear a good one -- and there is a lot of failure in the attempt; it's a difficult form -- is because it's so seldom true now that you hear people speak under circumstances where they assume they are obliged to speak seriously and in good faith, and the people who hear them are assumed to be listening seriously and in good faith. This is a kind of standard of discourse that is not characteristic of the present moment. I think that it makes a sermon, when it is a good sermon, stand out in anyone's experience.
She also has this to say about 'The Protestant Imagination':
Protestantism, of course, is much more explicitly divided into different traditions -- the Pentecostals, the Anglicans. But there is the main tradition of Protestantism that comes out of the Reformation and that produced people like Kant and Hegel and so on, who are not normally thought of as being people writing in a theological tradition, although Hegel, of course, wrote theology his whole life. I think, frankly, that his PHENOMENOLOGY OF SPIRIT is theology, too.When the Reformation became established, one of the things that was a question between Catholicism and the Reformation traditions was whether there was a hierarchy of being. If you look at Thomas Aquinas, for example, you have hierarchies of angels and all the rest of it, and hierarchies even of saints and then subsaints -- people who aren't quite there, that sort of thing. The Reformation rejected all of that and created a new metaphysics, in effect, that is not hierarchical. The idea that the universe itself is physically structured around hierarchy was sort of an integration of earlier science and theology that was made by people like Thomas Aquinas, that was assumed doctrinally in that tradition. The Reformation rejected that model of reality and created a highly individualistic metaphysics in the sense that it located everything normative that can be said about reality in human perception, there being, of course, no other avenue of knowing. There is Scripture, there is conscience, there is perception itself. If you read Calvin, for example, he says, How do we know that we are godlike, in the image of God? Well, look at how brilliant we are. Look how we can solve problems even dreaming, which I think is true, which I've done myself. So instead of having an externalized model of reality with an objective structure, it has a model of reality that is basically continuously renegotiated in human perception. I think that view of things is pretty pervasively influential in Protestant thought.
