Hoping to join St. Ignatius of Loyola's new order of Jesuits and be a missionary to India, Philip was instead guided by Providence to seek out the poor and abandoned youth of Rome to catechize them in the faith and help them find a better life. He became the founder of the religious congregation, the Oratory, that worked with the youth and also labored to re-evangelize a decadent Rome.
