“Certainly Christianity is in the first place a religion, but not merely a religion. It is an entirely new life that can penetrate and enliven every life sphere and life form. Thus Christianity is not coextensive with the church. It is far too rich to allow itself to be pressed within its walls. Indeed, it would not be the true religion if it had no influence on the richly fulsome human life. Christianity cannot be restricted to the church as an historical organization viewed as a visible community. For that reason we speak of a Christian society, of a Christian school. There is nothing human that cannot be called Christian. Everything within and outside the church that is enlivened and governed by Christ who exercises sovereignty over all things, constitutes and belongs to the Kingdom of God.”
