The first decade of James I's reign saw a wave of high-profile clerical conversions to the Church of Rome. Among the best-known cases are those of James Wadsworth, who travelled to Spain with Sir Charles Cornwallis's embassy in 1605, where, as William Bedell's biographer Alexander Clogie disgustedly recalled, he was ‘cheated out of his religion by the Jesuits and turned apostate’; Theophilus Higgons, a member of Christ Church, Oxford, who converted in 1607; his friend and Oxford contemporary Humphrey Leech, who followed him in 1609 and later joined the Society of Jesus; and Benjamin Carier, a royal chaplain and prebendary of Canterbury, who converted in 1613. As the work of Michael Questier has taught us, religious conversion was by no means an uncommon phenomenon in early modern England. Yet these cases had the potential to inflict serious damage on the Jacobean church, not only because they threatened to neutralise the propaganda advantages to be gained from Roman Catholic converts to the Church of England such as Marc’ Antonio de Dominis, but also because they drew unwelcome attention to doctrinal divisions within the Church of England over such issues as anti-popery and the theology of grace.
