In order to understand why as Catholics, we believe that Jesus Christ is truly present in the consecrated host and wine, we must go to Jesus’ own words in the institution of the Mass, “While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying: «Take and eat; this is my body». Then he took a cup, and when he had given thanks, he gave it to them, saying: «Drink from it, all of you, this is my blood…” (Matthew 26:26-28), and then instructs us to repeat this formula in his memory (Luke 22:19).
It is when the priest pronounces these words that we usually hear the ringing of the bells fixing our attention on our Lord Jesus Christ, present truly, really and substantially in the Blessed Sacrament; and it is the time when some people out of devotion repeat the words of St. Thomas, “My Lord and my God” (John 20:28). It is worth mentioning that these words should be said instead, in the interior of our hearts; the consecration, being part of the actions of the one who presides at the Mass, must be pronounced in a clear and loud voice. Therefore, while the priest consecrates the offerings, there should be no singing, prayers, or music whatsoever (GIRM 32). The act of elevating the body and blood of Christ is part of consecration.
Now, why is it important to recognize the real presence of Jesus Christ in the consecrated host, because it is the means by which we will have eternal life! Only by eating His flesh and drinking His blood, through consecrated bread and wine, can we attain the grace of eternal life (John 6:22-59).
That is why it is very important not only to attend Holy Mass but also to participate in the supper that our Lord has prepared for us. Our Lord has prepared a banquet where the main course He offers us is eternal life through His body and blood.
Let us then throw off the rags that are our sins (Matthew 22:1-14), let us get ready and share with Christ the great banquet that He offers us in the Holy Communion
