Mick Gordon and Chris Wilkinson interviewed religious and non-religious people on the nature of religion (in a recommended book Conversations on Religion, Continuum, 2008). They started each interview with, "Do you have a working definition of religion?"
Rowan Williams, the Anglican Archbishop of Canterbury (UK) replied:
A working definition, I think, would have to be a set of habits: habits of speaking, habits of imagining, habits of behaving physically. Habits which are intended to anchor you in relation to something invisible, incomprehensible, and challenging.
Williams later says that these habits are formed by stories that people tell and which then become the basis of a relationship of trust.
I read that and then the rest of the interview. It could have been in Swahili (which I don't speak by the way) for all I really "grocked". Though highly-educated Williams uses incomprehensible language (I think) to speak about something incomprehensible.
Can we ever talk the same language?
