The most significant of Godfrey's writings are transcriptions of Quodlibets, for which he participated in fifteen of during his tenure at the University of Paris. These were week-long sessions held before Christmas and Easter in which participating Masters were required to answer questions chosen by their students. This was taxing to the Master, who would have to argue a thoughtful and researched answer on an incredibly diverse range of subjects. Many Masters chose not to engage in the Quodlibets. Godfrey of Fontaines completed at least fifteen Quodlibetal sessions. Hence, Godfrey discussed a very wide range of issues. These and other writings show him to have been not merely a distinguished theologian and philosopher, but also a canonist, jurist, moralist, and conversationalist, who took an active part in the various ecclesiastical, doctrinal, and disciplinary disputes that stirred Paris at that period.
