Revivalism was one of the main causes of division in nineteenth century British Methodism, but the role of revivalist theology in these splits has received scant scholarly attention. In this book, James E. Pedlar demonstrates how the revivalist variant of Methodist spirituality and theology empowered its adherents and helped foster new movements, even as it undermined the Spirit’s work through the structures of the church. Beginning with an examination of unresolved issues in John Wesley’s ecclesiology, Pedlar identifies a trend of increasing marginalization of the church among revivalists, via an examination of three key figures: Hugh Bourne (1772-1852), James Caughey (1810-1891), and William Booth (1860-1932). He concludes by examining the more catholic and irenic theology of Samuel Chadwick (1860-1932), the leading Methodist revivalist of the early twentieth century who became a strong advocate of Methodist Union. Pedlar shows that these theological differences must be considered, alongside social and political factors, in any well-rounded assessment of the division and eventual reunification of British Methodism.

The term "charism" is drawn originally from Pauline literature and refers to a gift given by the Spirit for the upbuilding of the body of Christ. Since the mid-twentieth century, Christians from a broad spectrum of theological positions have applied this term, in varying ways, to groups within the Church. However, no book thus far has provided a rigorous and sustained critical investigation of this idea of ecclesial charisms. In Division, Diversity, and Unity, James E. Pedlar provides such an investigation, drawing on biblical and systematic theology as well as literature on church renewal and ecumenism. Against those who justify denominational separation in order to preserve particular gifts of the Spirit, Pedlar insists that the theology of charisms supports visible, organic unity as the ecumenical ideal. Division, Diversity, and Unity argues that the theology of ecclesial charisms can account for legitimately diverse specialized vocational movements in the Church but cannot account for a legitimate diversity of separated churches. Pedlar tests and develops his constructive proposal against the fascinating and conflicted histories of two evangelistic movements: the Paulist Fathers and The Salvation Army. While the proposed theology of ecclesial charisms stakes out a legitimate and important place in the Church for specialized movements, it excludes any attempt to justify the permanent separation of an ecclesial body on the basis of an appeal to an ecclesial charism.
