RT Article T1 Witnessing Together - Who, What and to Whom? The Concept of Witness in Together Towards Life and The Church: Towards a Common Vision JF Ecclesiology VO 15 IS 3 SP 261 OP 282 A1 Heikkilä, Ida 1986- LA English PB Brill YR 2019 UL https://ixtheo.de/Record/168370021X AB ‘Witness' belongs to the central vocabulary of contemporary ecumenism. Despite its ecumenically significant role the concept has not been defined in ecumenical dialogues, neither analysed in academic research. Already a rough mapping of dialogue documents shows that the concept is used in various ways and contexts but not in a coherent or conscious way. This article studies the meaning of ‘witness' in two ecumenical documents issued by the World Council of Churches, ‘Together towards Life. Mission and Evangelism in Changing Landscapes' (2012) and ‘The Church: Towards a Common Vision' (2013). Both documents see witness as the characteristically Christian way of participating in the mission of the Triune God but give it different roles in the life of the church.
