The life of St. Philip Neri is full of miracles, and one that has become famous over the years concerns his heart.
He felt his heart grow bigger one day, and after his death this was confirmed.
According to the Catholic Encyclopedia, the miracle occurred shortly before the feast of Pentecost.
For the rest of his life St. Philip Neri was fueled by an intense divine love and possessed a joy that was contagious.
While typically these types of experiences remain in the spiritual realm, it was later confirmed that his heart did in fact grow larger.
The autopsy confirmed this story from his life and was an added impetus to his eventual canonization.
It is an astonishing miracle, one that highlights the power of God's love and how the gifts of the Holy Spirit can truly set us on fire, helping us spread love everywhere we go.
