Shoulder wound of Jesus
The traditional prayer in honor of the shoulder wound of Jesus calls to mind the wound that Jesus is said to have received carrying the cross on which he was crucified. It is variously attributed to Saint Bernard of Clairvaux or to Saint Gertrude or Saint Mechtilde.
According to pious legend, Saint Bernard asked Jesus which was his greatest unrecorded suffering and the wound that inflicted the most pain on him in Calvary. Jesus answered: "I had on my shoulder, while I bore my cross on the Way of Sorrows, a grievous wound which was more painful than the others and which is not recorded by men."
Prayer
In English:The modern version of the prayer bears the imprimatur of Thomas Daniel Beaven, who was the Bishop of Springfield in Massachusetts from 1892 to 1920.
Revelation to Padre Pio
Padre Pio of Pietrelcina venerated the shoulder wound of Jesus, and bore it himself as a stigmata.According to Stefano Campanella, author of "Il papa e il frate", Karol Wojtyła, while still a priest, visited Padre Pio and asked the question of which was his most painful wound – much like the manner Bernard did to Christ. Wojtyła expected that it was Pio's chest wound, but Pio replied: "It is my shoulder wound, which no one knows about and has never been cured or treated".
