St Bernard of Clairvaux received some revelations from Jesus. He asked Jesus what His most painful wound was. Jesus replied “I had a wound 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. Honour this wound with thy devotion and I will grant thee whatsoever thou dost ask through its virtue and merit.”
Jesus revealed some profound promises to St Bernard: “In regard to all those who shall venerate this wound, I will remit to them all their venial sins, and I will no longer remember their mortal sins.”
Below is the prayer to honour the shoulder wound of Jesus
O Loving Jesus, meek Lamb of God, I miserable sinner, salute and worship the most Sacred Wound of Thy Shoulder on which Thou didst bear Thy heavy Cross, which so tore Thy flesh and laid bare Thy Bones as to inflict on Thee an anguish greater than any other wound of Thy Most Blessed Body. I adore Thee, O Jesus most sorrowful; I praise and glorify Thee, and give Thee thanks for this most sacred and painful Wound, beseeching Thee by that exceeding pain, and by the crushing burden of Thy heavy Cross to be merciful to me, a sinner, to forgive me all my mortal and venial sins, and to lead me on towards Heaven along the Way of Thy Cross. Amen.
Father Wojtyla (the future Pope John Paul 2) one day asked St Pio (The famous Priest who bore the Stigmata for 50 years) which wound caused him the most pain, he expected St Pio to say the wound of his chest, but St Pio replied: “It is my shoulder wound, which no one knows about and has never been cured or treated.”
It is said Br Modestino was assigned the task of taking an inventory of all St Pio’s belongings after he had died, he discovered that St Pio’s undershirt bore a circle of blood stains on the area of the right shoulder. He asked St Pio in prayer to reveal to him the truth of this. At 1am in the morning he awoke with a terrible pain in his shoulder, as though being stabbed by a knife, it only lasted a short time and then there was the perfume of flowers (the sign of St Pio’s presence). He then heard the voice of St Pio say: “This is what I had to suffer”
