The ecumenical movement has made enormous progress in resolving major doctrinal issues dividing Christian churches worldwide. Now the focus turns to the Christian moral life (ethics) which in turn is rooted in the nature of the church itself. On both of these the churches continue to be divided. This course examines the bases of church division, past and current, along with differing and at times divisive views of the church itself. This lays the ground work for discussing how and why ethics is now divisive in a way not known in the past, and what are some avenues forward to greater unity.
