Several bulls followed the deputies to Paris. The prudence and kindness of S. Louis helped greatly to restore peace between the University and the friars. The University seal was set to the summons addressed to SS. Thomas and Bonaventura to take their doctor's degrees, which had been delayed two years by the troubles. S. Thomas thought many other Dominicans more deserving of the honour than himself. Whilst sadly meditating on this, he thought an old man appeared to him, asking the cause of his sadness. He replied, "It is not right that they should force me to take rank among the doctors, a thing of which I am not capable." The old man said, "The order thou hast received is assurance enough; it destroys thy own will, and points to God's will in that of thy superiors. Take as the text of thy thesis: '_He watereth the hills from above: the earth is filled with the fruit of Thy works._ Ps. ciii. 13.'" On the morrow, after a struggle between S. Bonaventura and himself for the last place, Thomas, as being the younger, gained it. He preached from the text given him, and it has been regarded as a prophecy of the influence which the new doctor was to exercise over Christendom. The day on which he took his degree was the 23rd October, 1257. The epoch on which we have now entered is the most glorious period of our saint's life. The star of his genius mounted, without a cloud to obscure it, in the firmament of the Church. In spite of all the eulogies of his contemporaries, it is difficult for us to comprehend now-a-days the extent of the power which Aquinas exercised over the men and the ideas of his time. S. Thomas now drew up his famous "Summa contra Gentiles." He begins this treatise by stating that he will discuss all questions on the ground of human reason, seeking therein a common ground on which to combat his adversaries, or rather seeking in their natural intelligence a point on which to rest that bridge which might lead them from human reason to the truth of God; then he establishes the necessity of faith; he shows next that reason affords ground for expecting a supernatural revelation; lastly, he cements together reason and faith. Then he makes his general division: he considers God in Himself, in relation to men, and men in relation to God. To these three parts he joins a fourth, viz., revelation properly so-called; therein he expounds the Trinity, the Incarnation, with all the dogmas which attach themselves to it, the whole destiny of man in the plan of Christianity. This we may call the theological evolution of his great work. In that which may be called its philosophical introduction he resolves all such difficult questions; as the falsehood of pantheism, evil and its origin, its nature, and its effects, which he turns into a proof of God's existence in opposition to those unquiet spirits, who saw in it a reason for doubting His existence. This work was followed immediately by one upon all the Epistles of S. Paul.
