Methodists have had an ambivalent relationship with peace. In this paper I outline some directions in which Methodists might develop their peace theology through different aspects of worship. John Wesley's most common use of the word peace was still found in the Church of England Evensong service: "peace, which passes all understanding". This is a direct quotation of Philippians 4:7 that serves as a benediction. The peace of God here is the peace of heart and mind. Worldly peace is now understood much better in secular thought, but does not have enough of a role in our Christian ethical thought and moral formation. This presentation will examine what role worship can play in promoting an understanding of Christian ethical and spiritual formation with peace at its centre. This will highlight the different aspects of Methodist worship (prayer, reading of scripture, preaching, sacrament, song), but also the wider context of worship's role in creating peace within and between churches and the wider community. Given the central importance of worship to Methodist churches, the paper will conclude with lessons that might be applied for the development of more peaceable worshipping communities.
