Saint Vincent Ferrer, O.P., (†1419) was a Spanish Dominican friar, renowned preacher, and missionary. Born in Valencia, he entered the Dominican Order at 18 and studied theology in Barcelona and Toulouse. Known for his fiery sermons, he traveled across Europe, preaching repentance and conversion, earning the title "Angel of the Apocalypse." Vincent played a key role in resolving the Western Schism, supporting Pope Benedict XIII. His miracles, including healings, bolstered his reputation. He founded the Fraternity of the Most Holy Name of Jesus. Canonized in 1455 by Pope Callixtus III, his feast day is April 5. Vincent remains a patron of Valencia and builders.
