As a die-hard Latin-Mass going traditional Catholic who recently bought the Anglican Use DVD and BDW, I LOVE the prayer of Humble Access. Beautiful, Beautiful prayer.
We do not presume to come to this thy Table, O merciful Lord, trusting in our own righteousness, but in thy manifold and great mercies. We are not worthy so much as to gather up the crumbs under thy Table. But thou art the same Lord whose property is always to have mercy. Grant us therefore, gracious Lord, so to eat the Flesh of thy dear Son Jesus Christ, and to drink his Blood, that we may evermore dwell in him, and he in us.
In the use of Anglicans, there is more:
...to drink His blood, 'that our sinful bodies may be made clean by His body and our souls washed through His most precious blood'.
This preserves the reason we communicate.
Almighty God, Father of our Lord Jesus Christ, Maker of all things, Judge of all men, we acknowledge and bewail our manifold sins and wickedness, which we from time to time most greivously have committed, by thought, word, and deed, against thy Divine Majesty, Provoking most justly thy wrath and indignation against us...
And then after the General Confession and the Absolution was done, the Priest would say something that I still remember, I loved to hear him say:
Hear what comfortable words our Saviour Christ saith unto all who truly turn unto him:
Come unto me all ye who travail and are heavy laden, and I will refresh thee.
That is an awesome prayer; thanks for posting it!
One of my favorites is the prayer prayed silently by the priest at the conclusion of the Maronite Divine Liturgy.
Remain in peace, O holy altar of God. I hope to return to you in peace. May the offering I have received from you, forgive my sins and prepare me to stand blameless before the throne of Christ. I know not whether I will be able to return to you again to offer sacrifice. Guard me, O Lord, and protect your holy Church, that she may be the way of salvation and the light of the world. Amen.
