The era of the Reformation profoundly changed the papal institution. In Italy, it allowed for the assertion of primatial authority and a greater oversight of the Italian Church as well as a capacity to influence popular and elite culture through the medium of the Inquisition and the Index. Rather than attempting to achieve Italian liberty, it now strove to protect the peace and religious orthodoxy of the peninsula. In the wider European sphere, during this period the papacy effectively lost contact with most of Protestant Europe, but through an articulated system of nunciatures and, from 1622, through Propaganda Fide, it remained an important influence throughout the Catholic world, projecting itself as a peacemaker among secular powers, the foe of heresy and Islam, the upholder of the decrees of Trent – conceived, however, as a prescriptive set of disciplinary and doctrinal norms – and the defender of ecclesiastical jurisdiction and privileges.

The controversies that plagued the Critica sacra described in Chapter 3 took place while it was in manuscript. Chapter 4 shows what happened when it finally found its way into print, prompting considerable debate in both Catholic and Protestant Europe. In the former, it focuses on how the work was received in Rome, tracking the lengthy investigation it was subject to at the Congregation of the Index and then the Holy Office. In the latter, it charts the wide-ranging public disputes the work elicited, paying particular attention to reconstructing the scholarly views and methods that underpinned Johann Buxtorf II and Archbishop James Ussher’s engagement with Cappel’s work.

Chapter 6 shows how the later 1650s and 1660s defy ready categorisation, with the practices and tools of biblical scholarship being drawn on in a range of different ways in a range of different contexts. Its three parts proceed concurrently, rather than chronologically, and successively analyse: the way in which debate concerning the Old Testament became increasingly polemical, framed in terms of a choice between the Masoretic Hebrew text or the Septuagint; how biblical scholarship differed according to different local settings (in this case Italy (and especially Rome) and the Dutch Republic); and how Benedict de Spinoza, comparatively disconnected from the confessionalised world of Old Testament scholarship, targeted a precise set of the views concerning the Bible held by others in his local Reformed and Jewish communities.
