This work tries to update the carefully analyzed historical context of the Barmen Theological Declaration of 1934 to a new, this time Indonesian context: the church struggle from 1992 to 1998 in the Batak church. The broad ecumenical issue is not only important for the European context and the dialogue with Euro-Islam that begins there. It is also of great importance in the African and Asian context for the coexistence of Jews, Christians and Muslims.
