Saint Lawrence is a Doctor of the Church. He was born Caesar de Rossi in 1559 in Naples. Before he went to study in Venice, he studied with the Conventual Franciscans. There he discerned a call to enter the Capuchin Franciscans and took the name Lawrence.
He worked as a diplomat for the secular powers in Europe and as a missionary as he is fluent in Hebrew and an expert in the Bible. In 1596, he was commissioned by the Pope to work for the conversion of the Jewish people and to combat the spread of Protestantism. He was a great preacher and refused a second term as minister general of his order in favor of preaching. He died in 1619.
