Its a Catholic thing – but its not something that you non-Catholics can’t understand. Essentially, Divine Mercy Sunday is a feast of God’s mercy. I pray that all will turn towards God and allow his endless flood of mercy to overcome all those things which hold a person apart from God.
Eternal Father, I offer You the Body and Blood, Soul and Divinity of Your dearly beloved Son, Our Lord Jesus Christ, in atonement for our sins and those of the whole world.
For the sake of His sorrowful Passion, have mercy on us and on the whole world.
God bless one and all.
