If the gospel is to challenge the public life of our society, if Christians are to occupy the ‘high ground’ which they vacated in the noontime of ‘modernity,’ it will not be by forming a Christian political party, or by aggressive propaganda campaigns. Once again it has to be said that there can be no going back to the ’Constantianian’ era. It will only be by movements that begin with the local congregation in which the reality of the new creation is present, known, and experienced, and from which men and women will go into every sector of public life . . . as sign, instrument, and foretaste of God’s redeeming grace for the whole life of society.
