The same reason which caused the Festival of the Holy Trinity, induced the Catholic Church to institute the festival of Corpus Christi, which we celebrate today. She requires that we shall confess and renew today the faith which we have in the Blessed Eucharist, and that we bestow all possible honors upon the Most Holy Sacrament and give due thanks to our Saviour for its institution. In order that this just requirement of the Church may be more fully complied with, we shall here give some explanation of the above reasons. In regard to the first reason, the following are the facts, which the church especially desires to call to our memory by this joyous festival. Our dear Saviour, on the same evening when His bitter suffering for the redemption of man began, instituted the Blessed Eucharist, out of His immeasurable love for us. In it He is truly and substantially present with body and soul, with flesh and blood, as God and Man, under the form of bread and wine. Under the form of bread, not only His holy body, but also His holy blood is present; because a living body cannot exist without blood. Hence he receives it, who partakes of holy communion only in the form of bread, not less than he who receives it in two forms, as the priests, when they say holy Mass. The latter partake of holy communion under two forms, in order that the passion and death of our Saviour, during which His blood flowed from His wounds, might be more vividly represented.

From the moment that the priest speaks the prescribed holy words, in the name of Christ, over the bread and wine, the Lord is present in the Holy Sacrament. Bread and wine change their substance miraculously into the true body and blood of the Saviour, in such a manner, that all that remains of the bread and wine is their form, color and taste. The presence of Christ lasts so long as the bread and the wine are unconsumed. It is further to be considered that our Lord is present in a small host as well as in a large one, as well in a portion of a host as in a whole one. Hence he who receives an entire host, has no more than he who receives only a part of one, the latter has just as much as the former. The same is the case with those who by inadvertence receive more than one Host, while others receive only one. It is only to be remarked that in case a consecrated Host is broken or divided, the holy body of the Saviour is not broken nor divided, but the form of the bread only: even as Christ will not again die, so his holy body can neither be broken nor divided. All these points are articles of faith in the Catholic Church, and are explained in sermons, in religious instructions and in many books, and are especially demonstrated by the word of God. All true Catholics believe this without any doubt, as the Almighty, who is eternal and infallible truth, has revealed it, and as that Church assures us, which on account of the assistance of the Holy Ghost, promised to her by Christ, cannot err.

Those who are not Catholics teach in many points quite differently. They especially reject the real presence of Christ in the form of bread and wine, and also the transubstantiation of these latter into the real body and blood of the Lord. They maintain it to be impossible that bread and wine can be changed into the body and blood of Christ, or that Christ can be really present at the same time, in so many different places, in so small a compass as the holy Host. If we ask them why they consider it impossible, they answer: "because we cannot conceive, cannot comprehend, how it can be possible." But if they believe impossible all which they cannot understand, they must, besides many other articles of faith, reject the creation of the world; the humanity and resurrection of Christ; the Holy Trinity; because all these are just as inconceivable for the mind of man, as the transubstantiation of the bread and wine and the substantial presence of the Lord in the Blessed Sacrament. It matters not in articles of faith whether we are able to comprehend them or not so long as they are revealed by God.

That which the Almighty has revealed must be true, whether I can understand it or not: for He is omniscient, hence infallible, and cannot be deceived, while our understanding can as easily be deceived as our senses. God is truth: therefore can not deceive. He is omnipotent; hence He can do more than the human mind can comprehend. "With God all things are possible," said Christ Himself. "Let us admit that God can do more than we are able to fathom," says St. Augustine, while St. Cyril of Alexandria writes; "The Lord says by the prophet Isaias: 'My counsel is not like yours, neither are my ways like your ways: for as the heaven is above the earth, so are my ways above your ways and my thoughts above your thoughts.' Cannot therefore the works of Him, who stands so high above us in wisdom and power, exceed in their greatness the limits of our understanding?"

The same is taught by all the Holy Fathers. They also refer to many occurrences in nature, which, although we cannot comprehend them, nevertheless take place. They speak of the creation of the world, and say, if we believe that God created a whole world out of nothing, how can we hesitate to believe that He can change bread and wine, or that He can be present in that form? The water at Cana was changed into wine: why then should He not possess the power to transform bread and wine into His holy body and blood? Truly, whoever believes that God is omnipotent, infallible and infinite, cannot doubt this article of faith. We Catholics believe so, and hence we cannot doubt any of the above mentioned points of the true faith. This faith we this day renew and confess publicly. The Catholic Church requires it, and has for this reason instituted today's Festival. She further demands that we unanimously, bestow today all possible honor upon the Blessed Sacrament, and that we praise and glorify with all the powers of our soul, the Saviour therein concealed. And is not this justly demanded of us? of us who firmly believe that our Lord is present in His double nature as God and as man, in the Blessed Sacrament? All honor, all praise belongs to the true God.

King David, in the Old Testament, bestowed great honor upon the Ark of the Covenant, in which a part of the manna was preserved, as Holy Writ relates. The manna of the Old Testament was only a feeble type of our Most Holy Sacrament, as Christ Himself teaches: hence we owe so much greater honor to it. The wise man said, many thousand years ago: "Glorify the Lord, as much as you can . . . Bless ye the Lord, exalt Him as much as you can." (Eccl. xliii.) As we are assured by our faith that our God and Lord is truly and substantially present in the Blessed Sacrament, it is natural that we honor, praise and glorify Him with all our strength. We are bound to do this not merely today, but during the whole year. Who is there, however, that can say of himself that he has not sometimes been remiss in this sacred duty? Hence the Holy Church requires that we, remembering our duty this day, kindle anew our zeal, if it has abated, and thus with united hearts, honor, praise and exalt the Most Holy Sacrament. For this purpose she has also ordained that the Blessed Sacrament shall be carried through the streets in solemn processions.

Everything connected with this ceremony is intended to honor our Lord in every possible manner. The Church tries, by this public manifestation, to atone somewhat for the many and great wrongs to which the Blessed Sacrament is so frequently subjected by heretics as well as by Catholics. One cannot, without horror, think how this sacred mystery has been assailed and dishonored in centuries gone by, and down to our days. A pious Christian dares not even relate the wrongs done to it, which are great enough to deserve hell. And what does our Saviour, concealed in the Blessed Sacrament, suffer from those who believe in his presence? The irreverence and levity with which many Christians conduct themselves in presence of the Blessed Eucharist, tend to dishonor and disgrace our Saviour. The unworthy communions which unhappily take place, offend Him in a most grievous manner. The misuse of the body, especially of the tongue and mouth, which are so often sanctified by partaking of the true body and blood of Christ, cannot but excite the wrath of the Lord. For these, as well as other wrongs done to the Blessed Sacrament, the Church of Christ seeks to make amends by these solemn processions, and by all the other pious exercises she has ordained for this festival and during the whole octave. Hence, every pious Christian should be solicitous to conform to the ordinances of the Church, and not only assist in the procession and all other devout exercises, but also endeavour to contribute to render them what the Church desires.

Those who are not Catholics disapprove of every thing that we do today in honor of the blessed Sacrament, and accuse us of idolatry, as we according to them, worship bread. They say also that all that we do in this regard cannot be agreeable to God, because it was not ordained by Him. We, Catholics, are, however, not disturbed by this, for we know that we do not worship bread, but Him whom three wise men worshipped in the manger, namely, Jesus Christ, true God and Man. We know also that though what we do this day in honor of the blessed Sacrament is not especially and expressly ordained in Holy Writ, still we are assured that a voluntary worship of it is in accordance with reason and the laws of God, pleasing and agreeable to His Majesty. And this is made clear to us from the above-mentioned example of the three Wise Men, and from the acts with which King David honored the Most High, on the solemn return of the Ark of the Covenant; not to mention that Christ gave us a general command to worship God, in the words: "The Lord thy God shalt thou adore and him only shalt thou serve." (Matth. iv.) This command we fulfil today by our actions, as they all aim at one end, namely, the honor of the Lord, who is concealed in the Blessed Sacrament. The more we are blamed and derided by the heretics for our adoration of the Holy Eucharist, the more fervent should we become in our zeal. When King David was derided by Michol, on account of his devotion at the return of the Ark of the Covenant, he said: "Before the Lord who chose me . . . . I will both play and make myself meaner than I have done, and I will be little in my own eyes." (II. Kings vi.)

We will still add in a few words, what the true Church further demands of us. We today give humble thanks to the Lord for the institution of the Blessed Eucharist. This is no more than our duty: for if we are obliged to thank God for the smallest benefit He confers upon us, we are surely under much greater obligation when the benefit is great and of especial importance. Who can tell, who can comprehend the greatness of the benefit, which Christ our Saviour and Lord bestowed upon us by the institution of the Blessed Eucharist. It is as great as it is unfathomable: great as He who devised it; as Christ our Lord, true God and man, the King of all Kings, the Lord of all who reign. Great and inconceivable is the miracle by which the substance of bread and wine is changed into the substance of the body and blood of Christ, and the miraculous presence of the Lord in the form of bread and wine. St. Thomas of Aquin calls the Blessed Sacrament a miracle, and the greatest that Christ ever wrought.

Inexpressibly great must have been the love which induced the Saviour not only to institute it at the time He chose for it, namely, the evening before His Passion. Since the world was created, there has never been found a parent willing to nourish his children with his own body, much as he may have loved them. Such excess of love Christ alone manifested. "Having loved His own, He loved them unto the end," writes St. John (John, xiii.). Already had He loved them and had given them many indubitable proofs of His love; but at the end of His life, He gave them one which surpassed all others, namely, having nourished them with His own body and blood, He instituted a sacrament, by means of which all the faithful might partake of this divine food. And when did He institute this? St. Paul writes: "In the night when He was delivered into the hands of the embittered Jews." The last night of His life was approaching, and the time when his enemies would seize Him, scourge Him most cruelly, crown Him with thorns, and nail Him like the greatest malefactor to the Cross. All this was known to the Lord. He knew also the wrong which would be done to Him in the Blessed Eucharist to the end of time: and yet this was not sufficient to prevent Him from instituting it.


Truly, a love which surpasses all the bounds, not only of human, but angelic understanding. Love seeks to be always with the loved ones and to enjoy their presence. Jesus Christ, who out of love to us had descended from heaven upon earth, had remained with us for 33 years: and it was the will of His heavenly Father that, after having accomplished our Redemption, He should return to heaven. This also took place; but His infinite love for us found a means by which He will remain with us in the world until the end of time. This means is the Blessed Sacrament, which He instituted before the commencement of His bitter passion. In it He is God and Man, as He is in heaven, truly and substantially present in every Church where the Blessed Sacrament is kept. By this same blessed Sacrament, He unites Himself most closely with us, when we partake of it, because He gives Himself to us as food, and nourishment. And this union with us is, according to the opinion of the Holy Fathers, a still greater proof of His love for us, than His presence in the Sacrament. It is the property of love to unite closely those who love one another: can there be a more intimate union than ours is with Christ, by virtue of the Holy Sacrament?

When Christ became man, He united His divine nature, in an incomprehensible manner, with humanity. When we partake of the Blessed Eucharist, He unites His divine and human natures with our nature, although not in the same manner as when He became Man. "He that eateth my flesh and drinketh my blood," says He, "abideth in me, and I in him." (John, vi.) How wonderful a union! How incomprehensibly great a love!

Besides the love which induced our Lord to institute the Most Holy Sacrament, the end for which He instituted it, and with which we have already become partly acquainted, is also great and most excellent. Our adorable Saviour would leave us in it an eternal memorial of His love and of His bitter passion and death, as His own words make clear to us: "Do this for a commemoration of me." (Luke, xxn.) He desired to remain constantly with us, in order that we might, in all our cares, go to Him with greater confidence, and opening our hearts to Him, request and receive from Him, comfort, strength and help. It was His wish that His holy flesh and blood should nourish and strengthen our souls. This was the intention, the end and aim of our Lord in instituting the Most Holy Eucharist. As the religion He founded is holy and most perfect, and as no true religion can exist without sacrifice, He would leave us for evermore the most divine sacrifice, namely, His own flesh and blood that we might sacrifice it in holy Mass in honor of the Majesty of God, as a thanks-offering for all graces and benefits bestowed upon us; for the pardon of our sins, for the obtaining of new grace, and for the comfort of all, living and dead. How high, how admirable an end and aim! Had Christ been willing to remain among us, in the Blessed Eucharist, only in one place on earth, in order that we might there lay our burdens more trustingly at His feet, He would then have conferred on us a favor, which we could never sufficiently esteem, and for which we could never be sufficiently thankful. How much greater, therefore, is the grace that He dwells among us in so many different places of the world, to nourish our souls and to serve as sacrifice, and this not once only, but as often as we desire. How inexpressibly great a favor! How wonderful an invention of truly Divine love!

Just as great and excellent are the results of the Blessed Sacrament. Our Lord expressed it all in a few words when He said: "If any man eat of this bread, he shall live forever." (John, vi.) Which means: Whoever worthily partakes of this holy Sacrament, shall receive the special grace of God to preserve the life of his soul, or to remain in the sanctifying grace of God, and hence obtain life everlasting. By virtue of this Sacrament, man receives strength to abstain from sin, to resist temptation and to serve the Most High with constant fidelity. Therefore it is called by the Council of Trent, a medicine, by the strength of which we are freed from our daily iniquities, and protected and guarded against great crimes. "This divine mystery," says Albert the Great, "strengthens man in grace and succors him when he is in danger of committing sin." The pious Thomas a Kempis writes: "This most holy and venerable Sacrament conduces to the well-being of body and soul. It is the remedy for spiritual weakness. It heals the wounds of vice, it keeps within bounds all evil inclination, it conquers temptations, gives more abundance of grace, multiplies virtue, strengthens faith, augments hope, and inflames love."

Other teachers say, that Christ instituted the Blessed Sacrament under the form of a bodily food, that we might more easily perceive its effects. For, as bodily food preserves the life of the body, renews strength, refreshes man: thus is the spiritual life of the soul preserved by the holy Eucharist, the soul is strengthened, and all the inner faculties of man inflamed with new zeal in the service of the Almighty. The true Church has not hesitated, for causes already mentioned, to call it a pledge of future glory, so that those who worthily partake of Holy Communion, receive, so to speak, an assurance of eternal salvation. I say, who partake worthily of the Holy Communion; for, one who receives it when not in the state of grace, will not only fail to share in the benefits it imparts, but becomes guilty of eternal punishment, according to the words of St. Paul: "For he that eateth and drinketh unworthily, eateth and drinketh judgment to himself" (i Cor. xi.) that is, as St. Chrysostom and other holy fathers teach, damnation.

Whoever reflects on what we have said, cannot but come to the conclusion, that the Lord, by instituting the Blessed Eucharist, has bestowed upon us an inexpressibly great gift. Hence, it is only our duty to give Him our most humble thanks, to which effect the Church has ordained today's festival, demanding of us to give thanks to the Lord for the institution of this Blessed Gift.


So much for the reason which gave rise to the ordinance of the festival of Corpus Christi. Only one point must I yet touch upon, to confirm the true faith and at the same time give an instruction. The non-Catholics maintain that we act wrongly in not administering the Blessed Sacrament in two forms, as Christ our Lord instituted it and commanded it to be partaken of in such a manner. To this I answer, Luther himself more than once said that the real Blessed Eucharist was to be found in the Catholic Church; and that it mattered not whether it is administered under one form or under two. It is true that Christ instituted it in two forms, but that He commands all to receive it in two forms is false. From the act of the institution of the Eucharist this cannot be proved: for, Christ instituted and adminstered it after washing his disciples' feet. He gave it only to the men, the strong, and this after they had partaken of supper, and yet the non-Catholics do not say that it is a commandment to wash the feet before Holy Communion, or administer it only to men, the strong, and after supper. The non-Catholics may rest assured that we are more favored when we partake of Holy Communion in one form than they, even if they received it in a hundred: for we receive under one form really the flesh and blood of Christ, while they, under two forms, neither partake of the Saviour's holy flesh nor of His blood, because they possess no priests to whom Christ gave power to consecrate.

You have considered the aim and end of today's festival and also the reasons that gave rise to it: hence, prepare your devotions accordingly. First, exercise yourself today in the virtue of faith. Confess to God and the whole world that you believe everything that God the Lord has revealed of the Blessed Eucharist, and which His true Church explains to you; and that you will believe it for no other reason than because the infallible truth has revealed it. Confess openly, that you willingly give your reason up in the service of the Almighty. Oppose, in advance, all temptations by which the Evil One might endanger the peace of your soul, during your life, or while on your death-bed in regard to the Blessed Eucharist or other articles of faith. Manifest openly the faith which you bear in your heart and be not ashamed of it in the presence of heretics. Hence, accompany the procession today with due reverence, and assist, today and always, in all public devotions ordained in honor of the Holy Eucharist. In the churches where the Blessed Sacrament is kept, show your faith in the presence of the Lord by your modesty and reverence. Whoever is wanting in this is wanting also in faith.

Secondly, endeavor especially today to honor, with every power of your soul, the Most Holy Sacrament, but let not your devotion cease with this day: continue in it as long as your life lasts. Accompany the Holy Eucharist devoutly when it is carried in processions; frequently visit the churches where it is kept; worship it in deepest humility. Assist at Holy Mass, if possible, daily. Receive the Holy Communion as often as your confessor will permit; but always with a heart purified and adorned by exercises of virtue. Take time for devotions before and after Holy Communion. Guard yourself in the presence of the Holy Sacrament, from everything that might be displeasing to Him who is concealed in it: as, unrestrained roving of the mind and eyes; the volubility of the tongue; irreverent manner, &c. Take care that you do not, by using indecent language, soil your tongue, which has been purified by partaking of the Holy Sacrament. Before all things, however, take care that you do not receive the Holy Eucharist while a mortal sin weighs upon your soul, for this would be the greatest insult, the most frightful disgrace to your loving Jesus, and to you it might bring eternal damnation. Beg your Saviour also to pardon every irreverence of which during your past life, you have been guilty in presence of the Blessed Sacrament, or in your Communions. To this end, offer to Him everything that is done in the whole world today and during the entire Octave, to His honor and glory, and make the firm resolution to amend all your faults by redoubled zeal in honoring the holy Sacrament.

Thirdly: In consideration of the infinite benefit which our Lord has conferred upon us in instituting the Blessed Eucharist, return Him your most fervent thanks. Give thanks to Him that He made you a member of that Church, which alone is in possession of the Blessed Eucharist. Thank Him also that He gives you time and opportunity to partake frequently of the Holy Sacrament. And as everything connected with it is great and holy, so on your side, all in regard to it should be great and holy. Great must be your faith in the real presence of Christ; great your zeal to worship Him; great your reverence for the church in which He dwells; great your devotion to Him in the Sacrament; great your preparation to receive it. Let all the powers of your mind be directed towards one end: cleanse your soul from every stain of sin, and adorn it most beautifully by exercises of virtue, to make it a fit dwelling for your Saviour. When King Solomon was about to erect a temporal dwelling for the Most High, he collected gold and silver, precious stones and other treasures, saying: "I have prepared, according to my strength, all that is necessary for the dwelling of my Lord." Why? He gives his reason in the following words: "For, it is a great work, because we erect a house, not for man, but for God." (I. Par. 29.) Through Holy Communion, your soul becomes a much more real temple of God than the Temple which Solomon erected: hence your care in preparing this dwelling should be much greater than that of Solomon. Finally, great should be your solicitude, after Holy Communion, to remain with Christ in your heart, and to thank, praise and love Him. Oh! exert all the powers of your soul; "for it is a great work!"
