A great quote from Barth’s Evangelical Theology:
The community speaks in the surrounding world by the positions it assumes on the political, social, and cultural problems of the world. But the question of truth also concerns the community’s order of worship, discipline, constitution, and administration, as well as its quiet ministerial work. . . . Christian witness must always be forged anew in the fire of the question of truth. Otherwise it can in no case and at no time be a witness that is substantial and responsible, and consequently trustworthy and forceful. Theology is no undertaking that can be blithely surrendered to others by anyone engaged in the ministry of God’s Word. It is no hobby of some especially interested and gifted individuals. A community that is awake and conscious of its commission and task in the world will of necessity be a theologically interested community.
