The gospel is always conveyed through the medium of culture. It becomes good news to lost and broken humanity as it is incarnated in the world through God’s sent people, the church. To be faithful to its calling, the church must be contextual, that is, it must be culturally relevant within a specific setting. The church relates constantly and dynamically both to the Gospel and to its contextual reality. …In order to contextualize responsibly, the church must assess its culture critically, discerning and unmasking its philosophical foundations and values.

– Craig Van Gelder, in Missional Church
