We have been doing this with Guantanamo, debt, economic crisis, art, the walk of faith, etc etc etc and I have to say I am loving it and long may it continue.
If you have a spare 30 mins and are interested in HIV/Aids here is a great paper from the UN of all people about a theological reflection on the stigma of HIV/Aids. It's an interesting e.g of wrestling with a particular 'now' issue (or better a 'now' suffering of people in our global community) and what our response may be as a supposed 'kingdom of priests' who mediate God in the world. Enjoy and if it's an issue close to your heart you might like to get involved with the great work tearfund or christian aid do around it.
*Contextual theology is not - abandoning the Bible, or 'Truth', or mission etc etc. It's based on a simple acknowledgement that we all know and act in a context. However hard we try that will always be the case. That doesn't mean it legitimises a 'me-centric' view of the God/the world. In fact it is all about me being honest about my/our 'me-centricness' and trying humbly to 'work out' what God is saying in my/our situation. God made us and put us in, meets us in, is present in and calls us to follow him and bring his good news in our context and that seems like a wonderful thing not something to be scared of.
