THE RELATION BETWEEN TRINITY AND ECCLESIOLOGY AS AN ECUMENICAL CHALLENGE AND ITS CONSEQUENCES FOR THE UNDERSTANDING OF MISSION

Both the new trinitarian-based koinonia concept in World Council of Churches Faith and Order's thinking on church unity, and the increasingly trinitarian understanding of missio Dei in recent church thinking on the theology of mission, are based on a return to the common trinitarian understanding of God. Haudel analyzes the causes and ecumenical consequences of this development, as well as the danger of unconsidered references to the trinitarian doctrine of the nature of God.
