The Glossa is a compilation of footnotes and margin notes to describe or clarify words, phrases, and ideas.
The Glossa Ordinaria
The Ordinary Gloss, known as the Glossa ordinaria, is an important witness to the position of the Western Church on the status of the Apocrypha because it was the standard authoritative biblical commentary for the whole Western Church. It carried immense authority and was used in all the schools for the training of theologians. The New Catholic Encyclopedia describes its importance:
A designation given during the Middle Ages to certain compilations of ‘glosses’ on the text of a given MS. The earliest Glossa ordinaria is that made of the Bible, probably made in the 12th century…Although glosses originally consisted of a few words only, they grew in length as glossators enlarged them with their own comments and quotations from the Fathers. Thus the tiny gloss evolved into a running commentary of an entire book. The best-known commentary of this type is the vast Glossa ordinaria of the 12th and 13th centuries…So great was the influence of the Glossa ordinaria on Biblical and philosophical studies in the Middle Ages that it was called ‘the tongue of Scripture’ and ‘the bible of scholasticism’.119
Karlfried Froehlich summarizes the importance, authority and influence of the Glossa ordinaria on the Middle Ages:
For medieval Christians this tool was supremely necessary, indispensable for the reading of the sacred book which could not be understood without it. In their preface of 1617, taking up Peter Lombard’s remark about the Gloss as the ‘tongue’ of Scripture, the Douai theologians gave voice to this sentiment. Many generations, they suggested, 'thought of this collection of scriptural interpretation so highly that they called it the “normal tongue” (glossa ordinaria), the very language (lingua) of Scripture, as it were. When Scripture speaks with it, we understand. But when we read the sacred words without it, we think we hear a language which we do not know.'120
Alister McGrath adds these comments:
…the Glossa Ordinaria may be regarded as a composite running commentary upon the text of the bible, characterized by its brevity, clarity and authoritativeness, drawing upon the chief sources of the patristic period…So influential did this commentary become that, by the end of the twelfth century, much biblical commentary and exegesis was reduced to restating the comments of the gloss.121
The original Glossa ordinaria began as a marginal gloss on the Bible and was attributed to Walafrid Strabo in the tenth century. Over time the interlinear gloss was added which most likely originated in the twelfth century with Anselm of Laon. Margaret Gibson confirms this:
To this extent the old heresy is not without foundation: that Walafrid Strabo (a Carolingian) wrote the marginal gloss, whereas Anselm of Laon (the early scholastic) wrote the interlinear. The dating is sound enough.122
The work consisted of standard commentaries on the books of the Bible by major Church fathers and theologians from the Carolingian period. The principal Church fathers and theologians who provided authoritative commentary in the Gloss are described by Margaret Gibson:
Ultimately the principal contributor to the Gloss-the giant who bears it on his shoulders-is Jerome. He was responsible for the text of the Bible, for many of the explanatory prefaces to individual books, and for the learned and comprehensive exegesis of most of the Old Testament and part of the New. Behind Jerome stands Origen, whose work was known directly to Jerome but to later scholars indirectly (and partially) in Rufinus’ translation. Augustine contributed to Genesis and Ambrose to Luke; Cassiodorus to the Psalms, and Gregory the Great at least to Job and perhaps to Ezekiel and the Gospels. The next great figure is Bede. He is the leading player in Ezra-Nehemiah, Mark, the Acts of the Apostles and the Canonical Epistles. The basic material from Jerome to Bede, was edited in the ninth century by Rabanus Maurus, who commented the entire Old Testament (except Baruch) and much of the New. Paschasius Radbertus supplied a commentary on Lamentations and revised Jerome’s commentary on Matthew.123
