I'm reading a fantastic book at the moment called 'The Sparrow' by Mary Doria Russel. It is about a group of people, led by a Jesuit Priest, who travel to another planet where alien life has been discovered. Now that might sound a bit weird, but the questions and challenges it raises about mission, culture, contextualisation and the like are profound and numerous.
If you get a chance, read it.
It is affirming in me again and again the need for us to seriously consider and understand the culture we are thrust into and a part of and how the Church can properly and thoughtfully engage with this culture. So often we just don't think about it properly and then wonder why we struggle to engage with our community in significant and relevant ways with the gospel.
