He then began those labors that made him the most famous missionary of the fourteenth century. He evangelized nearly every province of Spain, and preached in France, Italy, Germany, Flanders, England, Scotland, and Ireland. Many 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 went to Granada, which was under the rule of Islam, and he preached the gospel with much success. He lived to see the end of the great schism and the election of Pope Martin V. Finally, having given his life to the preaching of the Faith, he died April 5, 1419.
O God, who didst vouchsafe to illumine thy Church by the merits and preaching of blessed Vincent thy Confessor: grant to us thy servants; that we may both be instructed by his example, and by his advocacy be delivered from all adversities; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
