Last month, the World Methodist Council brought together representatives from many of its constituent denominations in London to discuss issues related to migration. These included issues of joint ministry and polity that have arisen from situations where migrants from one Methodist tradition have formed churches in a geographic area in which another Methodist tradition predominates.
One result of that consultation is the statement "God Is On The Move: A Call to Be the Church in a New Way."
The statement speaks very positively about migration and migrants and affirms the importance of ministry with migrants and ministry by migrants. It also lays forth a set of principles for ministry collaboration between migrant and host Christian communities. The document and the principles are well worth a read.
