Over at 9Marks there is a good article by Michael Horton: Transforming Culture with a Messiah Complex. I think the point, which is a good one, is that it is the church that needs to disciple people so they transform culture and that it is not necessarily the churches place as an institution to do so. Near the end of the article, as an example, he speaks of the slave trade in England being stopped not by the church but by people such as Wilberforce who were “formed by the church’s ministry” that made the change.
