Philip Neri was a 16th-century Italian priest and influential reformer who lived in Florence and Rome. Born in 1515, he was ordained in 1551 and eventually became known as the Second Apostle of Rome due to his extensive pastoral work. He established the Congregation of the Oratory, a community of secular clergy, and founded the Confraternity of the Holy Trinity. His ministry focused on providing care to the sick, the impoverished, and those working as prostitutes in Rome.
