Humility of Grace
"Lord, I am not worthy to receive Your abundant graces, but only say the word and I shall be blessed."
Can be said repeately during walk to communion.
Continue to repeat till all communicants have received the Holy Eucharist.
Then say After Communion Prayers:
Anima Christi & St Michael the Archangel.
This is a simpler (easier to remember) version for the Lamb of God "Lord, I am not worthy that you should enter under my roof, but only say the word and my soul shall be healed".
Either can be said during walk to communion.
