I am the living bread which came down from heaven; if anyone eats of this bread, he will live forever; and the bread which I shall give for the life of the world is my flesh. John 6:51
My teacher taught us, “As a word, the term eucharist means thanksgiving. This name is given to the entire sacred meal-not only to the elements of bread and wine, but to the whole act of gathering, praying, reading the Holy Scriptures and proclaiming God’s Word, remembering Christ and eating and drinking his Body and Blood in communion with him and with God the Father, by the Holy Spirit. The word eucharist is used because the all-embracing meaning of the Lord’s Banquet is that of thanksgiving to God in Christ and the Holy Spirit for all that he has done in making, saving and glorifying the world.
The sacrament of the eucharist is also called holy communion since it is the mystical communion of men with God, with each other, and with all men and all things in him through Christ and the Spirit. The eucharistic liturgy is celebrated in the Church every Sunday, the Day of the Lord, as well as on feast days. Holy Communion strictly understood as being the real presence of Christ, his true Body and Blood mystically present in the bread and wine which are offered to the Father in his name and consecrated by the divine Spirit of God.” Fr.
