The World Council of Churches along with the Pontical Council for Interreligious Dialogue and The World Evangelical Alliance have just issued a document called Christian Witness in a Multi-Religious World
- Recommendations for Conduct.
The opening preamble says
Mission belongs to the very being of the church. Proclaiming the word of God and witnessing to the world is essential for every Christian. At the same time, it is necessary to do so according to gospel principles, with full respect and love for all human beings.
Aware of the tensions between people and communities of different religious convictions and the varied interpretations of Christian witness, the Pontifical Council for Interreligious Dialogue (PCID), the World Council of Churches (WCC) and, at the invitation of the WCC, the World Evangelical Alliance (WEA), met during a period of 5 years to reflect and produce this document to serve as a set of recommendations for conduct on Christian witness around the world. This document does not intend to be a theological statement on mission but to address practical issues associated with Christian witness in a multi-religious world.
The purpose of this document is to encourage churches, church councils and mission agencies to reflect on their current practices and to use the recommendations in this document to prepare, where appropriate, their own guidelines for their witness and mission among those of different religions and among those who do not profess any particular religion. It is hoped that Christians across the world will study this document in the light of their own practices in witnessing to their faith in Christ, both by word and deed.
