Abstract The ecumenical movement, and particularly my own Roman Catholic Church, has made significant progress in mutual recognition of baptism, prayer and dialogue between churches, and in common humanitarian and ecological work. We have been stymied, however, in the full recognition of our ecumenical partners’ eucharistic ministry, as well as by other aspects of ministry. Receptive ecumenism and growth in communion offer significant recourse for gradually developing the tools for this recognition. In this essay, I offer a trinitarian, baptismal, and cosmic context for discerning new possibilities for the recognition of ecumenical partners that do not centre their ecclesiology on episcopal ministry. Full recognition is of course beyond the scope of this article; I seek only to show how our shared trinitarian theology and cosmology might ground new approaches to recognition, particularly in grappling with different theologies of baptism and ministry.

Abstract This study explores the ways that the Eucharist can be seen to express the missiological life of the church. The article first tells the story of the evolution of the Five Marks of Mission, a description of Christian mission which is now widespread among the churches of the Anglican Communion and beyond. This story shows a shift in the way the nature of the church and its activities are understood and so uncovers certain ecclesiological indicators. The Eucharist as practised in this tradition is then examined to uncover ways in which it expresses these indicators. Various human actions within the liturgy are found to do this, showing that the Eucharist not only points to the Five Marks of Mission but can be seen to be an active embodiment of them and so properly be described as a sacrament of mission.
