To dishonour the Eucharist is to dishonour the Real Presence of Jesus in the Eucharist. Saint Paul stated: "Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be answerable for the body and blood of the Lord." [1 Cor. 11:27] Prior to approaching the Real Presence of Christ in the Eucharist, we should be cleansing our souls through the Sacrament of Confession.
In the Old Testament, we find instances where God promised to make His dwelling among us. "And have them make me a sanctuary, so that I may dwell among them." [Exo. 25:8]
I will place my dwelling in your midst, and I shall not adhor you. And I will walk among you, and will be your God, and you shall be my people." [Lev. 26:11-12]
When God asks that we make Him a sanctuary [Exo. 25:8], such requiring human effort and human labour, He is not referring to His indwelling of the Holy Spirit. He clearly is referring to a request for a building. In Lev. 26:11-12, we read that God will place His dwelling in our midst. Such a passage is prophetic of today's Church in which we find the Sacred Tabernacle in which dwells the Real Presence of Jesus in the Holy Eucharist.
In the New Testament, in the Book of Revelations, we read, "See the home of God is among mortals. He will dwell with them as their God; they will be his peoples, and God himself will be with them." [Rev. 21:3]
This last passage points out to the fulfillment of God's promises that are found in the Old Testament, that He would dwell among us. As long as there will be a Catholic Church, there will be a Sacred Tabernacle. And as long as there is a Sacred Tabernacle, there you will find the Real Presence of Jesus in the Holy Eucharist.
While it is easy for the Protestants to reject the Real Presence of Jesus in the Eucharist, they cannot explain the above passages. They simply overlook them as if they do not exist, consequently they deny that God is dwelling among Christians. If only they knew Who they were rejecting! If only they could perceive that He who they seek, He is here in our midst! If the Protestants were to perceive the mystery of the Real Presence, their Churches would disappear overnight.
