I also think that no single, individual theologian [WLS: and I would say this applies to anyone speaking on morals] is responsible for his or her theology. Each one lives from and depends on the communion of saints, on those who come before us and those who receive our work. An individual theologian’s work should not be discarded because of her or his failures because it is never solely their work. I do think we must raise questions as to the connection between theology and ethics that could lead a Barth or Yoder to their self-deception, especially when they themselves refused a sharp distinction between theology and ethics. Is there something in their theology that contributed to it?
So I have come to terms with these failures by thinking: 1. their theology cannot be wholly discarded because their theology was never their’s. They do not own it, and theologians are not individual heroes. 2. Theologians’ failures cannot be overlooked but must be considered as part and parcel of their theology. Many of us were attracted to Barth because he saw the failures of theology to resist the Nazis. If we easily overlook ethical and political failures, then we would have to say that theology makes little difference in the world and that would be devastating to the theological task.
