More on doubt with another Newbigin quote

How does God speak to humanity? A blog commenter offers this quote from Leslie Newbigin's "Truth and Authority in Modernity".

clipped from commongroundsonline.typepad.com "The other possibility is that divine revelation should be a matter of public history. In that case it can be only in events that are limited to a particular time, place, culture. But the whole ongoing course of human history cannot be frozen forever at a particular point. Revelation takes place only if...it is internalized, made part of a living human consciousness that must necessarily be the consciousness of a human being living in a particular time, place, and culture. It is therefore hard to imagine how there could be any other divine revelation authoritative for the whole of human history except one that embraced the three elements we have noted above: a living community, a tradition of teaching, and the continuing work of the divine Spirit illuminating the tradition in each new generation and each new situation, so that it becomes the living speech of God for that time, place, and culture."
