I just saw a Facebook post about a novena to St. Peregrine. I've been praying to him for a while now for a couple people I know who are fighting cancer. I know that he is the patron saint of cancer victims, but I just realized that other than that I know nothing about him.
This is his short bio from EWTN: St. Peregrine was born in 1260 at Forlì, Italy to an affluent family. He lived a comfortable life as a youth, and politically opposed the papacy. After he experienced the forgiveness of St. Philip Benizi, he changed his life and joined the Servite order. He was ordained a priest, and later returned to his home to establish a Servite community. There he was widely known for his preaching, penances, and counsel in the confessional. He was cured of cancer, after he received a vision of Christ on the cross reaching out His hand to touch his impaired limb. He died in 1345 and was canonized in 1726. He is the patron of cancer patients
Prayer to St. Peregrine
O great St. Peregrine, you have been called "The Mighty," "The Wonder-Worker," because of the numerous miracles which you have obtained from God for those who have had recourse to you. For so many years you bore in your own flesh this cancerous disease that destroys the very fibre of our being, and who had recourse to the source of all grace when the power of man could do no more. You were favored with the vision of Jesus coming down from His Cross to heal your affliction. Ask of God and Our Lady, the cure of the sick whom we entrust to you.
(Pause here and silently recall the names of the sick for whom you are praying)
Aided in this way by your powerful intercession, we shall sing to God, now and for all eternity, a song of gratitude for His great goodness and mercy.
