He is known as the ‘second apostle of Rome’. He was a great reformer distinguished from many others by the joy that was a hallmark of his life. He was born in Florence and was educated by the Dominicans. His early life was lived quite simply as he studied theology and philosphy. In 1544 his life was changed as he recalls in his biography:

“I found myself filled with the Spirit with such force that my heart began to palpitate within my body and I was inflamed with a great love….” He was ordained in 1551 and joined an association of secular priests known as San Girolamo. Philip encouraged many to pray together. Groups began meeting for spiritual reading, prayed together and visited ancient Roman basilicas as pilgrims. Volunteers who wanted to join became so numerous that some had to be turned away. New houses were started in Naples, Bologna and elsewhere in Italy. One writer described Philip as a man who miraculously enkindled in many a holy love of Christ.
