The happy commemoration of today’s feast with its immense concourse of people invites us to prolong fervently our praises of the Most Holy Body of Christ. What could be sweeter, what more pleasing to the heart of the faithful than to exalt the abyss of his divine charity, and to glorify the overflowing torrent of his love! At the table of the new grace the hand of the priest distributes ceaselessly his Flesh as food and his precious Blood as drink, to those who are his children and heirs of the kingdom promised by God to those who love him.
O endless Emanation of the goodness of God and of his immense love for us, admirable and worthy of all praise! In this sacrament, where all former sacrifices are done away with, he remains with us to the end of the world; he feeds the children of adoption with the bread of angels and inebriates them with filial love.
This is the food and drink for the elect, living bread and spiritual nourishment, remedy for daily weaknesses! It is the table which Christ has prepared for his friends and guests, like the one the father prepared for his son on the day of his return, to replace the symbolic lamb. This is the Passover in which the victim immolated is Christ; 0 Christ our Passover, you want us too to pass over from vice to virtue; as once you delivered the Jews, so now you set us free in spirit. You are the food that satisfies all but the most hardened; food that is eaten by faith, tasted by fervor, assimilated by charity. 0 viaticum of our pilgrimage, you lead travelers to the height of virtue. Confirm my heart in good, assure it in the paths of life, give joy to my soul, purify my thoughts.
The Eucharist is bread, real bread; we eat it without consuming or dividing it; it converts but itself is not changed; it gives strength without ever losing it; it gives perfection and suffices for salvation; it gives life, it confers grace, it remits sins. It is the food of souls, a food which enlightens the intelligence of the faithful, inflames their hearts, purifies them from their shortcomings, elevates their desires.
O chalice that holy souls love to drink of, chalice of fervor, chalice changed into the Blood of Christ, to seal the new Alliance, withdraw us the old leaven, fill our souls with yourself, that we may become a new paste and that we may go to the feast with the unleavened bread of sincerity and truth. For the Lamb without spot, who knows no touch or stain of any sin, ought to be eaten with unleavened bread. We should not approach without being cleansed by confession, without having a solid foundation of faith, without being in charity.
Come to the Lord’s supper, if you wish to come to the nuptials of the Lamb; there, we shall be inebriated with the riches of the house of God we shall see the King of glory and the God of hosts in all his beauty, shall eat this bread in the kingdom of the Father.
Thomas Aquinas, Lectionary and Martyrology, 288-289
