From the introduction:
In the Leuenberg Agreement, the signing churches committed themselves “to stand up for temporal justice and peace between individuals and nations.” (art. 11) They agreed that this would make it necessary to join with others in seeking common and appropriate criteria and play their part in applying these criteria, (ibid.) and that the struggle for justice and peace in the world would increasingly demand of the churches the acceptance of a common responsibility (art. 36)
The churches assumed this common responsibility to be an integral part of the credibility of the churches’ being one in their witness and service to the world, and that this involves a responsibility to examine carefully current issues of disagreement, (art. 29, 40).
