“The case for an incarnational approach to missional witness is based, on the one hand, on the character of the biblical record; that is, the way in which the church’s missionary vocation is shaped by the earthly ministry of Jesus. The emphasis upon the necessary congruence of witness is rooted in God’s way of revealing himself supremely and finally in the incarnation of Jesus. The comprehensiveness of the biblical understanding of witness calls for an incarnational interpretation.
On the other hand, this approach helps us deal with some serious problems in our particular Western context. We see in both our mission history and our current evangelistic practices so much that is contrary to the incarnational character of the gospel. We see a gospel of peace proclaimed in divisive, judgmental ways. We see a Gospel of love conveyed manipulatively, insensitively, condescendingly. We see a gospel of healing obscured by distortions that hurt people and evoke resentment.
Thus we arrive at the concept of incarnational witness as one way of expounding the character of our missionary vocation. In the incarnation of Jesus Christ, God revealed himself as the One who is with and for his creation.
Now, as the Risen Lord sends his Spirit to empower the church, we are called to become God’s people present in the world, with and for the world, like St. John pointing always to Christ. The most incarnational dimension of our witness is defined by the cross itself, as we experience with Jesus that bearing his cross transforms our suffering into witness.
Incarnational witness is, therefore, a way of describing Christian vocation in terms of Jesus Christ as the messenger, the message, and the model for all who follow after him. To speak of the incarnation missionally is to link who Jesus was, what Jesus did, and how he did it, in one great event that defines all that it means to be Christian.”
- Darrell Guder in The Incarnation and The Church’s Witness
I would would say there are multiple sides to the incarnational coin. Not only should our witness be enfleshed in action, our witness should also be enfleshed in the idiom of the people we are witnessing amongst. Not only do our actions need to match our words; when words do become necessary, as they do, they need to match our culture.
