Here I Receive Christ, My Soul’s Salvation.

Almighty and Eternal God,
I come to the sacrament
of your only-begotten Son, our Lord Jesus Christ.
As one sick I come to the Physician of life;
unclean, to the Fountain of mercy;
blind, to the Light of eternal splendor;
poor and needy to the Lord of heaven and earth.

Therefore, through your infinite mercy and generosity,
heal my weakness,
wash my uncleanness,
give light to my blindness,
enrich my poverty,
and clothe my nakedness.
May I thus receive the Bread of Angels,
the King of kings,
the Lord of lords,
with reverence and humility,
contrition and devotion,
purity and faith,
purpose and intention,
since here I receive Christ,
my soul’s salvation.

Grant that I may receive not only
the Sacrament of the body and blood of our Lord,
but also its full grace and power.
Give me the grace, most merciful God,
to receive the body of your only Son,
our Lord Jesus Christ,
born of the virgin Mary,
and unite me with his mystical body
and include me among his members.

Most loving Father,
grant that I may behold for all eternity,
face to face,
your beloved Son,
whom now on my pilgrimage,
I am about to receive in this sacrament,
who lives and reigns with you and the Holy Spirit,
one God, now and forever. Amen.

Grant, I beg of You, that I may receive not only the Sacrament of the Body and Blood of our Lord, but also its full grace and power. Give me the grace, most merciful God, to receive the Body of your only Son, our Lord Jesus Christ, born of the Virgin Mary, in such a manner that I may deserve to be intimately united with His mystical Body and to be numbered among His members. Most loving Father, grant that I may behold for all eternity face to face Your beloved Son, whom now, on my pilgrimage, I am about to receive under the sacramental veil, who lives and reigns with You, in the unity of the Holy Spirit, God, world without end. Amen.

Forgiveness and Salvation

Lord,
Father all-powerful,
and ever-living God,
I thank you,
for even though I am a sinner
in the kindness of your mercy
you have fed me
with the precious body and blood of your Son,
our Lord Jesus Christ.
I pray that this holy communion
may not bring me condemnation and punishment
but forgiveness and salvation.
May it be a helmet of faith and a shield of good will.
May it purify me from evil ways
and put an end to my evil passions.
May it bring me charity and patience,
humility and obedience,
and growth in power to do good.
May it be my strong defense against all my enemies,
visible and invisible,
and the perfect calming of all my evil impulses,
bodily and spiritual.
May it unite me more closely to you,
the one true God
and lead me safely through death
to everlasting happiness with you.
Lead me, a sinner, to the banquet,
where you with your Son and Holy Spirit,
there is true and perfect light,
total fulfillment,
everlasting joy,
gladness without end
and perfect happiness for your saints.
Grant this through Christ our Lord. Amen.

About the Eucharist, from the Didache

Now about the Eucharist, this is how to give thanks: First in connection with the cup:

We thank you, our Father, for the holy vine of David, your servant, which you have revealed through Jesus, your Son. To you be glory forever.

Then in connection with the piece broken off the loaf:

We thank you, our Father, for the life and knowledge which you have revealed through Jesus, your Son. To you be glory forever.

As this piece of bread was scattered over the hills  and then was brought together and made one, so let your Church be brought together from the ends of the earth into your Kingdom. For yours is the glory and the power through Jesus Christ forever.

You must not let anyone eat or drink of your Eucharist except those baptized in the Lord’s name. For in reference to this the Lord said, “Do not give what is sacred to dogs.”

After you have finished your meal, say grace in this way:

We thank you, holy Father, for your sacred name which you have lodged in our hearts, and for the knowledge and faith and immortality which you have revealed through Jesus, your Son. To you be glory forever.

Almighty Master, you have created everything for the sake of your name, and have given people food and drink to enjoy that they may thank you. But to us you have given spiritual food and drink and eternal life through Jesus, your Son.

Above all, we thank you that you are mighty. To you be glory forever.

Remember, Lord, your Church, to save it from all evil and to make it perfect by your love. Make it holy, and gather it together from the four winds into your Kingdom which you have made ready for it. For yours is the power and the glory forever.

Let grace come and let this world pass away.
Hosanna to the God of David!
If anyone is holy, let him come.
If not, let him repent.
Our Lord, come!
Amen.

The Didache also known as The Teaching of the Twelve Apostles, is a brief anonymous early Christian treatise, dated by most modern scholars to the first century. Some elements of The Didache are similar to the Gospel of Matthew, some seem to be apocryphal additions.

“As this piece of bread…” is similar in thought to 1 Corinthians 10:17.

“Do not give what is sacred to dogs” is from Matthew 7:6.

“But you have given spiritual food… is similar to 1 Corinthians 10:3.

“Remember, Lord, your Church, to save it from all evil…” is similar to
Matthew 6:13.

“Make it holy, and gather it together from the four winds…” is similar to
Matthew 24:31

“To you be glory forever” and “For yours is the power and the glory forever” is similar to Romans 11:36, Revelation 1:6, and many doxological phrases in the New Testament.
