The church has the character of a polis (the Greek word from which we get the adjective political), namely, a structured social body. It has its ways of making decisions, defining membership, and carrying out common tasks. That makes the Christian community a political entity in the simplest meaning of the term
…stated very formally, the pattern we shall discover is that the will of God for human socialness as a whole is prefigured by the shape to which the Body of Christ is called. Church and world are not two compartments under separate legislation or two institutions with contradictory assignments, but two levels of the pertinence of the same Lordship. The people of God is called to be today what the world is called to be ultimately.
