Catholics ask him
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 Godfor those who have had recourse to you.
For so many years you bore in your own fleshthis cancerous disease that destroys the very fibre of our being,and who had recourse to the source of all gracewhen the power of man could do no more.You were favored with the vision of Jesus coming down from His Crossto 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.Amen.
The Servites, his order, tell that Christ healed the cancer in his leg the night before the doctor was to cut it off. He had prayed before a crucifix, fallen asleep and dreamed that Jesus came down from the cross to heal him, and in the morning the doctor found no trace of the disease. The Servites call him their protector against cancer.
