Cultural Lenses and Worldviews

I wish we talked more about the importance of understanding the cultural lenses through which we view what Christianity should look like in church.  It's something we learn a lot about in school, but something that is rarely spoken about in church, at least not in any church I've ever been to.  In Samuel Escobar's The New Global Mission, Escobar quotes a section from the Lausanne Covenant which says,

Missions have all too frequently exported with the Gospel and alien culture and churches have sometimes been in bondage to culture rather than to the Scripture.  Christ's evangelists must humbly seek to empty themselves of all but their personal authenticity in order to become the servants of others, and churches must seek to transform and enrich the culture, all for the glory of God (par. 10).

I've participated in many conversations over the last three years that have had to do with the importance of recognizing my western lens through which I view the world and the importance of letting go of my own assumptions that I may attach to Christianity and the Gospel that may actually have nothing to do with either. And I always seem to get frustrated when I go into churches or hear others talking about what church should be like and their lists contain cultural practices rather than Biblical ones.  But maybe the problem is that the conversations about such issues remain among the leaders and never quite make it down to the average lay person.

So what if this changed?  What if we actually started educating our congregations on cultural lenses and worldviews and how these things play into how we view the Gospel?
