There are two people in my life right now who are battling cancer. One is the pastor of my parish, Fr David. He's been moved to a hospice following the failure of chemo, and he isn't doing well. The other is a lady I've known for most of my life, and who I consider to be family. St Peregrine is the patron Saint of cancer patients, so I am asking him to pray with me for these people. He is the patron of cancer patients because he himself was cured from cancer after seeing a vision of Jesus.
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 favoured 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.
