Thomas became the great friend of successive popes, some of whom had been brought in contact with him during his years of studying and teaching at Rome and Paris. This gave him many privileges and abundant encouragement, but finally came near ruining his career as a philosophic writer and teacher, since his papal friends wished to raise him to high ecclesiastical dignities. Urban IV. seems first to have thought of this but his successor Clement IV., one of the noblest churchmen of the period, who had himself wished to decline the papacy, actually made out the Bull, creating Thomas Archbishop of Naples. When this document was in due course presented to Aquinas, far from giving him any pleasure it proved a source of grief and pain. He saw the chance to do his life-work slipping from him. This was so evident to his friend the Pope that he withdrew the Bull and St. Thomas was left in peace during the rest of his career, and allowed to prosecute that one great object to which he had dedicated his mighty intellect. This was the summing up of all human knowledge in a work that would show the relation of the Creator to the creature, and apply the great principles of Greek philosophy to the sublime truths of Christianity. Had Thomas consented to accept the Archbishopric of Naples in all human probability, as Thomas's great English biographer remarks, the Summa Theologica would never have been written. It seems not unlikely that the dignity was pressed upon him by the Pope partly at the solicitation of powerful members of {285} his family, who hoped in this to have some compensation for their relative's having abandoned his opportunities for military and worldly glory. It is fortunate that their efforts failed, and it is only one of the many examples in history of the short-sightedness there may be in considerations that seem founded on the highest human prudence. Thomas was left free then to go on with his great work, and during the next five years he applied every spare moment to the completion of his Summa. More students have pronounced this the greatest work ever written than is true for any other text-book that has ever been used in schools. That it should be the basis of modern theological teaching after seven centuries is of itself quite sufficient to proclaim its merit. The men who are most enthusiastic about it are those who have used it the longest and who know it the best.
