William of Auvergne and the Manichees

Abstract

William of Auvergne became a master of theology in the University of Paris in 1223 and was appointed bishop of Paris by Gregory IX in 1228. William governed the church of Paris until his death in 1249, while continuing to write the works which constitute his immense Magisterium divinale et sapientiale. Despite the fact that he was the first of the thirteenth-century theologians to appreciate the value of the Aristotelian philosophy that poured into the Latin West during the last half of the twelfth and the beginning of the thirteenth century, his writings have not received the scholarly attention they deserve. Étienne Gilson has sketched well the impact of the influx of Greek and Arabian philosophical works into the Christian West: Up to the last years of the twelfth century, when the Christian world unexpectedly discovered the existence of non-Christian interpretations of the universe, Christian theology never had to concern itself with the fact that a non-Christian interpretation of the world as a whole, including man and his destiny, was still an open possibility.
