While Vincent wrought the Apostolic work of preaching committed to him, he lived ever as follows: Every morning he sang a solemn Mass, and every day he preached in public. He fasted every day, unless prevented by some absolute necessity. He refused to no one his holy and just advice. He never ate meat, nor wore linen. He quieted public disturbances, and negotiated the peace of kingdoms. When the seamless garment of the Church was rent by an horrid schism, he worked his every nerve to unite it again, and keep it one. He was a burning and shining light of all virtues, walking always in lowliness and simpleness, so that he meekly welcomed and embraced them which spake evil against him and persecuted him.
The Power of God confirmed his life and doctrine with many great signs and wonders. He often laid his hands upon the sick and they recovered. He cast out unclean spirits, and made the deaf to hear, the dumb to speak, and the blind to see. He cleansed the lepers, and raised the dead. After passing through many countries of Europe with exceeding profit to souls, worn out with age and disease, but still ever the same unwearied herald of the Gospel, he brought his life and his preaching together to an happy end, at Vannes in Brittany, in the year of salvation 1419. Pope Callistus III numbered him with the saints.
