To make church communion possible it is important to come to grips with the theological foundations of ecclesial community. Internationally composed doctrinal dialogue groups concern themselves with differences in teaching and central problems of the church in the present.
The CPCE is at the pulse of the times. In the specialist circles on Ethics and Ecumenics it has two expert bodies which enable it to speak on important ecclesiastical and political developments and bring the position of the churches into the channels of politics and civil society.
Church communion takes place in the meeting between people of protestant confession from different cultural and church environments. In consultations and conferences the CPCE offers a framework for such meetings to take place.
Church communion must be rooted locally. Within the CPCE this is done by the regional groups, which each gather together a segment of the member churches. They enable cooperation across boundaries, anchor the CPCE in their own context and bring the specific experiences of their regions into the work of the CPCE.
