Dietrich Bonhoeffer and Martin Luther King, Jr. are here reassessed for a new context and a new generation. Both combined activism, ministry, and theology. Both took on public roles in opposition to prevailing powers of their time. Both professed a kind of Christian realism and ended as martyrs to their respective causes. Here many of the leaders in Christian social thought revisit the insights, causes, and strategies that Bonhoeffer and King employed for a new generation and its concerns: race, reconciliation, nonviolence, political violence, Christian theological identity, and ministry.
