We've just walked from the searing heat of a glass blowing studio to the breezy streets of Adelaide and into a cool church. My body, clad in only a t-shirt prickles slightly with the fast cooling sweat. We've been enticed into a free tour of the church, the young woman taking us round is upbeat and informative. The church is neat, plain but with impressive stained glass windows shedding a relaxing half light into the lofty building. My lips taste of coffee, sweetened heavily with sugar. Inside the church is alive with voices, passionately discussing different aspects of the church and religion. It doesn't echo.
