Conrad De Guessia, his intimate friend, declared him to be: "A man of holy life and honest conversation, peaceful, sober, humble, quiet, devout, contemplative, and chaste; so mortified that he cared not what he ate or what he put on. Every day he celebrated with great devotion, or heard, one or two masses; and except in times proper for repose, he was occupied in reading, writing, praying or preaching." "His science, says Rainald, was not acquired by natural talent, but by the revelation and the infusion of the Holy Ghost, for he never set himself to write without having first prayed and wept. When he was in doubt, he had recourse to prayer, and with tears he returned, instructed and enlightened in his uncertainty." It was about this time that S. Thomas was ordained priest. It is mortifying that no certain information can be procured regarding the time at which it took place. All his biographers lay stress on his great devotion while celebrating. He was frequently rapt in spirit whilst at mass, when the tears would spring to his eyes, and flow copiously. After mass, he prepared his lectures, and then went to the schools. Next, he wrote or dictated to several scribes; then he dined, returned to his cell, and occupied himself with Divine things till time for rest; after which he wrote again, and thus ordered his life in the service of his Master. The duty of preaching also fell upon him. A man so filled with the Spirit of God would, almost of necessity, manifest the passion which ruled supreme. His reputation even at this period was great enough to draw a large congregation into the Dominican Church. The language in which at this period sermons were preached was the vernacular. Even when written in Latin, and this was generally the case, they were delivered to the people in the vernacular. The biographers of S. Thomas speak of the simplicity of his sermons. Once, in a discourse on the Passion, during Lent, he so vividly brought home to the congregation the sufferings of the cross, and drew so touching a picture of the compassion, mercy, and love of Christ, that his words were interrupted by the passionate crying of the people. On Easter Day, his sermon on the Resurrection filled the congregation with such jubilant triumph that they could scarcely be restrained from giving public expression to their feelings. In manner he was gentle, calm, self-possessed. Tocco says that preaching at Naples on the text, "Hail, Mary!" he was seen to keep his eyes closed in the pulpit, and his head in a position as if he were looking into heaven: he tells us also that the people reverenced his word as if it came from the mouth of God. In the two hundred and twenty-five skeleton sermons which he has left, he divides his subject into three or four grand divisions, which are again sub-divided into three or four sections.
