St. Vincent Ferrer is the patron saint of builders because of his fame for
"building up" and strengthening the Church:
through his preaching,
missionary work, in his
teachings, as confessor and
adviser. At Valencia in Spain, this illustrious son of St.
Dominic came into the world on January 23, 1357. In the year 1374, he entered the Order of St. Dominic in a monastery near his native city. Soon after his profession he was commissioned to deliver
lectures on philosophy. On
being sent to Barcelona, he
continued his scholastic
duties and at the same time
devoted himself to preaching. At Lerida, the famous university city of Catalonia, he received his doctorate. After this he labored six years in Valencia, during which time he perfected himself in the
Christian life. In 1390, he was obliged to accompany Cardinal Pedro de Luna to France, but he soon returned home. When, in 1394, de Luna himself had become Pope at Avignon he summoned St. Vincent and
made him Master of the sacred palace.
In this capacity St. Vincent made unsuccessful efforts to put an end to the great schism. He refused all ecclesiastical dignities, even the cardinal's hat, and only craved to be appointed apostolical missionary. Now began those labors that made him the famous missionary of the fourteenth century. He evangelized nearly every province of Spain, and preached in France, Italy, Germany, Flanders, England, Scotland, and Ireland. Numerous conversions followed his preaching, which God Himself assisted by the gift of miracles. Though the Church was then divided by the great schism, the saint was honorably received in the districts subject to the two claimants to the Papacy. He was even invited to Mohammedan Granada, where he preached the Gospel with much success. He lived to behold the end of the great schism and the election of Pope Martin V. Finally, crowned with labors, he died April 5, 1419. His feast day is April 5.
