The following quote is from a 1934 report published by the Baptist World Alliance commission on Nationalism. Nils Johan Nordström, Vice-President of the Swedish Baptists was the head of the commission. Historically the report is speaking about the issue of National Socalism that was growing in power and influence in Germany. I believe the quote below is still valid today:
We Baptists are convinced that the Church of Jesus Christ can never be a tool for nationalistic endeavours without losing her power and denying her mission to the world; that any sort of dependency on the State, which restricts her freedom to exercise love in the world, represents a real danger for the church and reduces her opportunities to carry the gospel to the ends of the world.
