This article provides a new perspective on the discussion of heresy from one of the most influential canonical-jurisprudential commentaries of the Middle Ages: Bernard of Parma's Glossa ordinaria to Pope Gregory IX's Decretales (commonly known as the Liber extra). Based on an analysis of Bernard's legal glosses, with special emphasis on his citation of Roman and canon law traditions, I argue that the often-overlooked Glossa ordinaria provides scholars a unique window into medieval conceptions of heresy, jurisprudence, and ecclesiastical-legal practice. This study demonstrates that this important mid-thirteenth-century legal-educational text not only reoriented the canonical definition of heretics toward an emphasis on sects rather than individuals, but, differing from the contemporary, often severe papal and conciliar rulings against heretics, also stressed the centrality of mercy and temperance in how heretics should be treated by the ecclesiastical court. The Glossa ordinaria, as this article discusses, might have served as an intellectual force that could have counter-balanced the overzealousness of emerging inquisitors in an age of intensifying repression of heretics.

Recent scholarship has shown a revived interest in twelfth-century biblical commentaries and exegesis, particularly in and around Laon. In this essay, we argue that a certain kind of exegetical world was being forged in twelfth-century Laon which prepared the way for the widespread success of the Glossa ordinaria, both as a book form and as a bearer of certain theological ideas and exegetical techniques. Based on our examination of the manuscript evidence, two main versions of the Matthew Gloss are discernible in that century. This discovery makes it possible for scholars to reconstruct a primitive version of the Gloss which existed prior to the one used by Comestor and others, should such an edition be deemed useful. By examining the relationship between pre-Glossa ordinaria glossed manuscripts of Matthew and various stand-alone commentaries like Cum post ascensionem, our work clarifies existing understandings of how the Matthew Gloss originated and developed. Although the Gloss initially drew from patristic and Carolingian sources and contemporary masters, the mise-en-page of the gloss-form invited continued modification, with later scribes adding or subtracting material and interweaving their own insights with received tradition. As masters, students, and scribes glossed manuscripts of Matthew from Laon near and far, they left a lasting impact on how Latin Christendom read, studied, discussed, preached from, copied, and wrote in their Bibles.

Peter Lombard's influential commentary on the Pauline Epistles, the Collectanea in omnes divi Pauli epistolas, has received little extended analysis in scholarly literature, despite its recognized importance both in its own right and as key for the development of his Sentences. This article presents a new approach to studying the Collectanea by analyzing how Lombard's commentary builds on the Glossa “Ordinaria” on the Pauline Epistles. The article argues for treating the Collectanea as a “historical act,” focusing on how Lombard engages with the biblical text and with authoritative sources within which he encounters the same biblical text embedded. The article further argues for the necessity of turning to the manuscripts of both the Collectanea and the Glossa, rather than continuing to rely on inadequate early modern printed editions or the Patrologia Latina. The article then uses Lombard's discussion of faith at Romans 1:17 as a case study, demonstrating the way in which Lombard begins from the Glossa, clarifies its ambiguities, and moves his analysis forward through his use of other auctoritates and theological quaestiones. A comparison with Lombard's treatment of faith in the Sentences highlights the close links between Lombard's biblical lectures and this later work. The article concludes by arguing that scholastic biblical exegesis and theology should be treated as primarily a classroom activity, with the glossed Bible as the central focus. Discussion of Lombard's work should draw on much recent scholarship that has begun to uncover the layers of orality within the textual history of scholastic works.

An assiduous interest in the plain sense of Scripture and shared interpretations of particular biblical passages can be observed in certain twelfth-century Jewish and Christian commentaries composed in northern France. While Hugh of Saint Victor and Rashbam engaged in independent endeavors to shed light on the sensus literalis and the peshat of Scripture, Andrew of Saint Victor attributed his knowledge of particular rabbinic interpretations to encounters with contemporary Jews. Yet points of convergence in Jewish and Christian exegesis can be observed even before the work of the Victorines and Rashi's disciples. The purpose of this study is to examine the midrashic interpretations transmitted in northern France around the beginning of the twelfth century in both the Glossa Ordinaria and Rashi's biblical commentaries. Interpretations are found in both corpora on occasions when their late-antique sources, such as Midrash Genesis Rabba and Jerome's Hebrew Questions on Genesis, themselves transmit similar insights. By analyzing an exposition found in both Rashi and the Gloss, the narrative of Abraham in the fiery furnace, this study seeks to clarify the nature and extent of this relationship. It thereby enables a more detailed understanding of the ways that midrash reached twelfth-century Jews and Christians and of how Rashi and the Gloss ensured the wide dissemination of these interpretations.
