Borrowing is a problem that Dietrich Bonhoeffer struggled with throughout his life and especially in active resistance to the Hitler dictatorship. We only "passively" share in the guilt of others (for example, in intercession), or we have to Become "actively" guilty (eg in resistance)? How is taking responsibility linked to responsible action? These and other questions are critically examined in relation to Bonhoeffer's entire works, especially his ethics.
