Why bother with Theology?

I'm back from a rich time at the Society of Vineyard Scholars. After sitting through papers and panels for 2.5 days, I've been asking myself, as I'm sure many other people would ask, 'why bother with all that theology?'

I've got a few days off, so will return at the start of next week with a response to that, and the rest of my promised Vineyard Church series, on it's distinctives and how they might be run against some of the theological issues the emerging church has been raising.
