To understand its importance, let us first read what our Holy Mother Church tells us: The Eucharist is the fount and apex of the whole Christian life (Lumen Gentium 11). The other sacraments, as well as with every ministry of the Church and every work of the apostolate, are tied together with the Eucharist and are directed toward it. The Most Blessed Eucharist contains the entire spiritual boon of the Church, that is, Christ himself, our Pasch and Living Bread (Prebysterorum Ordinis 5).
The saving efficacy of the sacrifice is fully realized when the Lord’s body and blood are received in communion. The Eucharistic Sacrifice is intrinsically directed to the inward union of the faithful with Christ through communion; we receive the very One who offered himself for us, we receive his body which he gave up for us on the Cross and his blood which he “poured out for many for the forgiveness of sins.” (Matthew 26:28). The Eucharist is a true banquet, in which Christ offers himself as our nourishment. When for the first time Jesus spoke of this food, his listeners were astonished and bewildered, which forced the Master to emphasize the objective truth of his words: “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life within you” (John 6:53). This is no metaphorical food: “My flesh is food indeed, and my blood is drink indeed” (John 6:55). (Ecclesia de Eucharistia 16)
It is therefore very important not only to attend the Holy Mass but to participate in the banquet that our Lord has prepared for us, a banquet where the main dish He offers us is eternal life through His body.
Let us then get rid of 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 Holy Communion.
