A scripture about government and society:
But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light. (1 Peter 2:9)
From Article 23 of the Confession of Faith from a Mennonite Perspective:
We believe that the church is God’s “holy nation,” called to give full allegiance to Christ its head and to witness to all nations about God’s saving love. The church is the spiritual, social, and political body that gives its allegiance to God alone. As citizens of God’s kingdom, we trust in the power of God’s love for our defense. The church knows no geographical boundaries and needs no violence for its protection. The only Christian nation is the church of Jesus Christ, made up of people from every tribe and nation, called to witness to God’s glory.
