To be prayed immediately after receiving Holy Communion on Divine Mercy Sunday
Lord Jesus Christ,
Son of the living God,
Have mercy on me,
A poor sinner.
Jesus, you promised St. Faustina
That the soul that has been to confession (I have),
And the soul that receives Holy Communion (I just did),
Will receive complete forgiveness
Of all sin and punishment.
Please give me this grace.
Amen.
