I adore You, O Glorious Cross, which was adorned with the Heart and Body of my Saviour Jesus Christ, stained and covered with blood. I adore you, O Holy Cross, out of love for Him, Jesus, who is my Saviour and my God.
Pope Pius the IX declared that by reciting this prayer 5 times on Friday, we release 5 souls from Purgatory and we release 33 souls by reciting it on Good Friday!
This prayer should be recited before a Crucifix, with a contrite heart and praying a few moments for the Pope.
