ABSTRACT
Walter Principe devoted a large part of his research in the medieval field to preparing a critical edition of the Quodlibets of Guerric of Saint-Quentin. This chapter focuses on some aspects of his Christology. The outlines of the literary heritage of Guerrie have gradually become clearer owing to the patient work of scholars throughout the twentieth century. Several articles in these Quodlibets concern Christ. Guerrie seems to have been the first to introduce in the study of Scripture a method of explanation based on the four causes. Until then that method had been reserved to the Faculty of Arts. By using it, he was able to highlight the content of the text with great vigour. In this he foreshadowed his successors, Albert the Great and Thomas Aquinas. Without giving it the same real importance, Guerric also raises the question of the necessity of Christ's passion for man's redemption.
