A slice of a brilliant moon, representing the life of the Church, was darkened, signifying the absence of a Feast to honor the Body and Blood of Christ. This was seen in a vision by the Norbentine nun responsible for the establishment of this Feast, St. Julianna of Liege. The Bull, establishing the Feast, was written in 1264 by Pope Urban IV, which I post below. This Feast was instituted for the universal Church, by the great hand of the good God through His Vicar, as a reminder to us to worship the ever present reality that is the presence of God in a visible form, the form of bread and wine. We would need to be exhorted to have a great love and an understanding as far as our human minds are capable of this great mystery that daily is oblated upon the altar of sacrifice, for the Blessed Sacrament would come under vicious attack in the near future after the institution of this holy Feast, firstly by the Protesants, who like those disciples who walked away from Our Lord at the mere mention of eating His Body; secondly, by those heretics within the Church from all time that denigrated the Blessed Sacrament; in modern times, by those Modernists, who having known what the Holy Eucharist is, have rejected it outright and encourage others to commit sacrilege against His Precious Body by receiving Him in the hand, not telling the truth about receiving in the state of mortal sin, by relegating the Holy Mass to a meal of bread.
As we celebrate this great Feast, let us make reparation for the crimes and sacrileges committed against the Blessed Sacrament throughout all time, especially in these modern times.
~Damsel of the Faith
Let us give all praise, honor and glory to the Most Blessed Sacrament today and forever!
About to pass from this world to the Father, our Saviour the Lord Jesus Christ, since the time of his Passion was at hand, instituted the great and wonderful Sacrament of his Body and Blood, bestowing his Body as food and his Blood as drink. For, as often as we eat this bread and drink this cup, we announce the death of the Lord. Indeed, at the institution of this Sacrament, he himself said to the Apostles: Do this in memory of me: so that for us the special and outstanding memorial of his love would be this venerable Sacrament; a memorial in which we attain the corporeal Presence of the Saviour himself.
Other things which we remember we embrace spiritually and mentally: we do not thereby obtain their real presence. However, in this sacramental commemoration, Jesus Christ is present with us in his proper substance, although under another form. As he was about to ascend into heaven, he said to the Apostles and their helpers, I will be with you all days even unto the consummation of the world. He comforted them with a gracious promise that he would remain and would be with them even by his corporeal presence. Therefore he gave himself as nourishment, so that, since man fell by means of the food of the death-giving tree; man is raised up by means of the food of the life-giving tree. Eating wounded us, and eating healed us. Thus the Saviour says, My Flesh is real food. This bread is taken but truly not consumed, because it is not transformed into the eater. Rather, if it is worthily received, the recipient is conformed to it.
We should celebrate continuously the memory of this memorial, because the more frequently his gift and favour are looked upon, so much the more firmly are they kept in memory. Therefore, although this memorial Sacrament is frequented in the daily solemnities of the Mass, we nevertheless think suitable and worthy that, at least once a year – especially to confound the lack of faith and the infamy of heretics – a more solemn and honourable memory of this Sacrament be held. This is so because on Holy Thursday, the day on which the Lord himself instituted this Sacrament, the universal Church, occupied with the reconciliation of penitents, blessing the chrism, fulfilling the Commandments about the washing of the feet and many other such things, is not sufficiently free to celebrate so great a Sacrament.
Moreover we know that, while we were constituted in a lesser office, it was divinely revealed to certain Catholics that a feast of this kind should be celebrated generally throughout the Church. Therefore, to strengthen and exalt the Catholic Faith, we decree that, besides the daily memory that the Church makes of this Sacrament, there be celebrated a more solemn and special annual memorial. Then let the hearts and mouths of all break forth in hymns of saving joy; then let faith sing, hope dance, charity exult, devotion applaud, the choir be jubilant, and purity delight. Then let each one with willing spirit and prompt will come together, laudably fulfilling his duties, celebrating the Solemnity of so great a Feast.
