Abstract The episcopal mission of Englishman John Bale to Ireland in 1553 provides historians with a unique window into the interconnected British and Irish histories of the early English Reformation. Scholarship on Bale has long explored his life and theology in all European theatres of the Reformation in which he was involved. Yet, key features of his mission and theology remain underappreciated. Building on recent work that has contextualized Bale’s Irish mission and ecclesiology within the imperial outlook of the Edwardian regime and Reformation, the article examines Bale’s mission against the worlds of English evangelical and continental Protestant political theology he inhabited, and the mingling of Henrician and Edwardian ‘reformist’ energies in Ireland with which it intersected and clashed. It argues that, under conditions of English colonial rule and empire in Ireland, Bale expressed a political theology that, imperial by circumstance and implication, turned his spiritual vocation modelled on Christ into a receptacle for divine and princely sovereignty that set rival conceptions of royal authority, idolatry, and Anglo-Irish constitutional relations against each other. Evangelical political theology thus acquired different hues on either side of the Irish Sea, with important implications for how we understand the early English Reformation across England and Ireland.
