Sensitive to a historiography of early modern trans-Atlantic growth which has sometimes struggled to integrate convincingly the stories of Protestants and Catholics into a unified whole, the present volume attempts to highlight the often surprising points of intersection between the two groups. The collection attempts to trace ‘some of the new kinds of religious relationships which were made possible within the Atlantic world’. Taken together, the eleven essays here represent an admirable attempt to capture the breadth and diversity of religious life in the emerging trans-Atlantic. The volume's geographic range encompasses both the expected English and North American locales, but also less extensively covered regions such as Ulster and English Jamaica. Many of the essays present case studies which illustrate a similarly wide swathe of ideas, movements and texts. Several of the individual contributions are especially noteworthy, a group headlined by David Manning's innovative analysis of intersecting Protestant and Catholic moral critiques produced in the wake of the 1692 Port Royal earthquake. Andrew Crome's essay sheds light on the Protestant appropriation of Catholic eschatological texts, while Francis Bremer presents fascinating case studies involving early modern families divided by diverging religious professions. These investigations of colliding religious cultures are complemented by those that focus their attention upon developments within a given theological and ecclesiastical context. Robert Armstrong, for example, helpfully illuminates the piety and thought patterns which defined Ulster Presbyterians during the late seventeenth century. Meanwhile, Michael Winship turns his attention to an intra-Protestant ecclesiological conflict during the late 1630s between English Presbyterian ministers and their Congregational counterparts in Massachusetts. Scott Spurlock's essay engages perhaps most directly with the collection's stated theme, as he examines the varied experiences of Catholics within the context of a decidedly Puritan English Atlantic. Although the collection's thematic diversity occasionally threatens to obscure its conceptual centre, many of the individual contributions are of a sufficiently high standard to effectively blunt these concerns. The volume takes an innovative approach to the intersection of Protestant and Catholic interests, and represents a welcome contribution to our understanding of the religious cultures nurtured by the expanding early modern trans-Atlantic.
