The Hebrews ate the flesh of the sacrificed animals; this was an image of our spiritual food. Now we eat, not the bodies of sacrificed animals, but the Most-pure Body and Blood of the Lord, throughout the whole earth. Therefore he who often communicates of the Holy Sacrament of the Body and Blood of Christ should not require to eat any animal food. Why should I require any animal flesh when I partake of the Most-pure Body and the Most-pure Blood—these life-giving Mysteries of my God? Do they not contain sufficient life, peace, joy, spiritual and bodily strength for me? Can I not be satisfied with only vegetable and fish food, which is much lighter for me?

What is there wonderful in the Lord’s offering you His Body and Blood as food and drink? He Who gave you as food the flesh of the animals He created, has finally given you Himself as food and drink. He who fed you at your mother’s breasts now feeds you with His own Body and Blood, in order that in the same manner as with your mother’s milk—you absorbed it into yourself in your infancy certain of your mother’s qualities—her spirit—so you may absorb into yourself, together with the Body and Blood of Christ the Savior, His spirit and life. Or as previously in your infancy you were fed by your mother and lived by her—by her milk—so now, having grown up and become a sinful man, you are fed with the Blood of your Life-giver, in order that through this you may live and spiritually grow into a man of God, a holy man. In short, that as you were then your mother’s son, so now you may become God’s child, brought up and fed with His Body and Blood, and, above all, with His Spirit (for His Body and Blood are spirit and life); and that you should become an heir of the heavenly kingdom, for which reason you were created, and for which you live.

Children! remember that Jesus Christ so loves you that He calls you several times every year to His Divine and Life-giving table, at which He gives you, as food, His own Divine, Most-pure Body; and, as drink, His Divine, Most-pure, Life-giving Blood, in order that you should live not only here temporarily, but also in heaven eternally, endlessly: and therefore be very, very thankful to your Creator and Savior for His immeasurable love to you, to your parents, to your brothers and sisters, and to all men.
