In this month's Quadrant there's a discussion of the public face of Christianity, noting the voice that the 'new atheists' have, but the lack of public involvement by Christian intellectuals in defending, explaining and applying their faith in critique of current culture (and not just mere moralising, for which the Church seems to be pegged).
They mention the Centre of Public Christianity, which is not too bad an endeavour, although I've criticised one of its people for their view of Genesis 1, etc. that fails to distinguish a Christian view from a Naturalist one, but the problem with such explicit missions to the contemporary mind is that it waves its flags and everyone ducks, dismissively.
I'd prefer to see Christian intellectuals in the 'marketplace' so to speak. Writing in the SMH Spectrum weekend magazine, in the Australian and Financial Review; having a strong, cogent and sufficiently well argued case to be listened to, because what they say is worth hearing.
This would be 'counter-ghettoing' after decades, if not a century of ghettoing, largely driven, I lead towards thinking, by the self-boosting ascendency of naturalism under the cover of its flag-ship, Darwinism. Christians in the public sphere have not come to grips with the strength of biblical creation and the weakness of materialism for engaging persons with their inevitable teleological concerns, and, given the popular interest in or commitment to Darwinism, at some level, and origins in general, they end up having nothing to say.
Interestingly in the Church itself the topic is avoided, as if there's an unspoken embarrasment at the doctrine of creation; yet whenever the topic and its related topics come up, they are received with vast interest and often debate (see this discussion). People at church think about and are interested in this topic, but the Church's servants so often skirt it.
