SOLEMNITY OF THE MOST HOLY BODY AND BLOOD OF CHRIST ( CORPUS CHRISTI SUNDAY)

Corpus Christi (Body and Blood of Christ) is a Eucharistic solemnity, or better, the solemn commemoration of the institution of that sacrament. It is, moreover, the Church's official act of homage and gratitude to Christ, who by instituting the Holy Eucharist gave to the Church her greatest treasure. Holy Thursday, assuredly, marks the anniversary of the institution, but the commemoration of the Lord's passion that very night suppresses the rejoicing proper to the occasion. Today's observance, therefore, accents the joyous aspect of Holy Thursday.

The Mass and the Office for the feast was edited or composed by St. Thomas Aquinas upon the request of Pope Urban IV in the year 1264. It is unquestionably a classic piece of liturgical work, wholly in accord with the best liturgical traditions. . . It is a perfect work of art.

— Excerpted from The Church's Year of Grace, Pius Parsch.

In the words of St. Thomas:

"How inestimable a dignity, beloved brethren, divine bounty has bestowed upon us Christians from the treasury of its infinite goodness! For there neither is nor ever has been a people to whom the gods were so nigh as our Lord and God is nigh unto us.

"Desirous that we be made partakers of His divinity, the only-begotten Son of God has taken to Himself our nature so that having become man, He would be enabled to make men gods. Whatever He assumed of our nature He wrought unto our salvation. For on the altar of the Cross He immolated to the Father His own Body as victim for our reconciliation and shed His blood both for our ransom and for our regeneration. Moreover, in order that a remembrance of so great benefits may always be with us, He has left us His Body as food and His Blood as drink under appearances of bread and wine.

"O banquet most precious! O banquet most admirable! O banquet overflowing with every spiritual delicacy! Can anything be more excellent than this repast, in which not the flesh of goats and heifers, as of old, but Christ the true God is given us for nourishment? What more wondrous than this holy sacrament! In it bread and wine are changed substantially, and under the appearance of a little bread and wine is had Christ Jesus, God and perfect Man. In this sacrament sins are purged away, virtues are increased, the soul is satiated with an abundance of every spiritual gift. No other sacrament is so beneficial. Since it was instituted unto the salvation of all, it is offered by Holy Church for the living and for the dead, that all may share in its treasures.

"My dearly beloved, is it not beyond human power to express the ineffable delicacy of this sacrament in which spiritual sweetness is tasted in its very source, in which is brought to mind the remembrance of that all-excelling charity which Christ showed in His sacred passion? Surely it was to impress more profoundly upon the hearts of the faithful the immensity of this charity that our loving Savior instituted this sacrament at the last supper when, having celebrated the Pasch with His disciples. He was about to leave the world and return to the Father. It was to serve as an unending remembrance of His passion, as the fulfillment of ancient types — this the greatest of His miracles. To those who sorrow over His departure He has given a unique solace."

Symbols: The usual symbol for the Holy Eucharist is a chalice, with a host rising out of it.

The chalice is shown with a hexagonal base, as a rule, symbolizing the Six Attributes of the Deity (power, wisdom, majesty, mercy, justice and love), and with a richly wrought stem of gold, studded with precious stones. The host is shown as the typical circular wafer, upon which may be imprinted the letters I. N. R. I., from which proceed rays of light, symbolical of the Real Presence, the substantial presence of Christ under the species of bread and wine.

An altar, upon which is set a cross, two or more candles in their tall candlesticks, a chalice and a ciborium, is another symbol often seen.

Ex 24:3-8

When Moses came to the people
and related all the words and ordinances of the LORD,
they all answered with one voice,
"We will do everything that the LORD has told us."
Moses then wrote down all the words of the LORD and,
rising early the next day,
he erected at the foot of the mountain an altar
and twelve pillars for the twelve tribes of Israel.
Then, having sent certain young men of the Israelites
to offer holocausts and sacrifice young bulls
as peace offerings to the LORD,
Moses took half of the blood and put it in large bowls;
the other half he splashed on the altar.
Taking the book of the covenant, he read it aloud to the people,
who answered, "All that the LORD has said, we will heed and do."
Then he took the blood and sprinkled it on the people, saying,
"This is the blood of the covenant
that the LORD has made with you
in accordance with all these words of his."

Heb 9:11-15

Brothers and sisters:
When Christ came as high priest
of the good things that have come to be,
passing through the greater and more perfect tabernacle
not made by hands, that is, not belonging to this creation,
he entered once for all into the sanctuary,
not with the blood of goats and calves
but with his own blood, thus obtaining eternal redemption.
For if the blood of goats and bulls
and the sprinkling of a heifer's ashes
can sanctify those who are defiled
so that their flesh is cleansed,
how much more will the blood of Christ,
who through the eternal Spirit offered himself unblemished to God,
cleanse our consciences from dead works
to worship the living God.

For this reason he is mediator of a new covenant:
since a death has taken place for deliverance
from transgressions under the first covenant,
those who are called may receive the promised eternal inheritance.

Gospel  

Mk 14:12-16, 22-26

On the first day of the Feast of Unleavened Bread,
when they sacrificed the Passover lamb,
Jesus' disciples said to him,
"Where do you want us to go
and prepare for you to eat the Passover?"
He sent two of his disciples and said to them,
"Go into the city and a man will meet you,
carrying a jar of water.
Follow him.
Wherever he enters, say to the master of the house,
'The Teacher says, "Where is my guest room
where I may eat the Passover with my disciples?"'
Then he will show you a large upper room furnished and ready.
Make the preparations for us there."
The disciples then went off, entered the city,
and found it just as he had told them;
and they prepared the Passover.

While they were eating,
he took bread, said the blessing,
broke it, gave it to them, and said,
"Take it; this is my body."
Then he took a cup, gave thanks, and gave it to them,
and they all drank from it.
He said to them,
"This is my blood of the covenant,
which will be shed for many.
Amen, I say to you,
I shall not drink again the fruit of the vine
until the day when I drink it new in the kingdom of God."
Then, after singing a hymn,
they went out to the Mount of Olives.
