05 April - Vincent Ferrier is a priest of the Dominican Order, born on 23 January 1350 near Valencia (Crown of Aragon) and died on 5 April 1419 in Vannes (Brittany).

Vincent is the fourth child of a man of Aragonese nobility, Guillem Ferrer, originally from Palamos and Constança Miquel. According to some legends, his father had a dream before his birth informing him that he would have a Dominican son. At the age of 19, Vincent Ferrer entered the Order of Preachers, commonly known as the Dominican Order. In his early years, he was tempted to leave the habit but his parents encouraged him to continue his formation. In 1379, he was ordained priest in Barcelona. At first he taught theology in Barcelona and then at the University of Lleida, where he obtained a doctorate in theology. He became known there for his talents as an orator.

Tireless preacher and evangelizer of Europe for twenty years, from 1399 until his death, he traveled throughout Spain, Italy, Switzerland, and even as far as Scotland. He was often accompanied by an impressive number of disciples, so much so that he had to preach in large outdoor spaces in order to be heard by the crowds. He is believed to have the gift of languages, given his ability to communicate with so many different peoples.

He addresses "the Jewish question" in Spain where he preaches the conversion of the Jews. For the historian Salomon Mitrani-Samarian, "while trying to moderate the savagery of the massacres, he brought into the bosom of the Church the unfortunate Jews who, in order to escape death, took refuge in the churches" and according to his apologists, converted 25,000 to 30,000 Jews; a rabbi of the time affirmed, with regret, that Vincent Ferrier had converted, in total, "more than 200,000 Jews".
