I'm at Wolfgang Simson's place in Korntal in the Black Forest for an interactive seminar with Afrikaans-Jewish Aussie Alan Hirsch, national director of Forge and co-author of 'The Shaping of Things to Come', one of the best books on church innovation and mission. Alan is a non-assuming guy with some bright insights on what made catalytic, exponentional church growth happen in the first century, and still makes it happen in China today. He calls it 'the apostolic genius', which he presented as a kind of molecular structure consisting of five (indispensable) elements centering on Christ: missional-incarnational impulse, apostolic enviroment, disciple-making, organic systems, and communitas (not community). We interacted on his input with 25 apostolic thinkers and practitioners, which I found truly enriching. Most of these elements I've been teaching on, and Alan's input helped me to fine-tune that.
