This is the truth.
And for me, my special devotion is to the Divine Mercy...For the sake of His sorrowful passion, have mercy on us, and on the whole world seems to be a prayer worth praying constantly for this poor sad world.
Me too! As you know .... the Divine Mercy chaplet ends with the Trisagion ....
Holy God
Holy Mighty One
Holy Immortal One
Have mercy on us!
I love that prayer, which I learned from the chaplet. Well, apparently it is a very ancient prayer from the East. In the Maronite Church, it is called the 'Qadeeshat'. After the priest has incensed the Sanctuary and the church, we all stand, and face East to the Tabernacle. Father then chants the 'Qadeeshat' 3 times in Syriac.
Qadeeshat Aloho
Qadeeshat Hyeltono
Qadeeshat Lomoyouto
To which the congregation chants - Itraham Alein - Have mercy on us.
This prayer never made it to the west until our Lord gave it St. Faustina. It must be so pleasing to Him!
