 Not surprisingly, Gregory’s ideas are often Augustinian. Gregory’s brand of doctrinal Augustinianism, influenced rather by the Franciscan and Oxonian tradition than the more Dominican (and Parisian) variety of Giles of Rome, soon dominated the Augustinian Hermits’ philosophy and theology. Thus by the early 16th century Aegidistae and Gregoriistae schools of thought existed, and a recognized via Gregorii was present in many universities such as Wittenberg, the university of Gregory’s fellow Augustinian Hermit Martin Luther (McGrath 1987). The fact that Gregory’s extreme Augustinian views on predestination became virtually official doctrine at the University of Vienna, and each book of his Sentences commentary was printed six times between 1482 and 1532, further helps explain why some of Gregory’s ideas often resemble those of Luther and Jean Calvin. Gregory’s thought had a life after the reformation, perhaps influencing Francisco Suarez, but certainly having an impact on seventeenth-century debates over such topics as predestination.
