the Catholic sacrament of Holy Eucharist?"
Answer: For Catholics, the Holy Eucharist / Catholic Mass is considered the most important and highest form of prayer. In fact, attending Mass is an obligation, under penalty of mortal sin, each Sunday and on certain other Holy Days of Obligation. The Mass is divided into two sections, the Liturgy of the Word and the Liturgy of the Eucharist.
In the book of Malachi, the prophet predicts elimination of the old sacrificial system and the institution of a new sacrifice: "I have no pleasure in you, says the Lord of hosts, and I will not accept an offering from your hand.
The Roman Catholic Church believes that the bread and wine of the Holy Eucharist become the actual body and blood of Jesus. They attempt to support their system of thought with passages such as John 6:32-58; Matthew 26:26; Luke 22:17-23; and 1 Corinthians 11:24-25. In A.D. 1551, the Counsel of Trent officially stated, "By the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood.
In Jewish thought, bread was equated with the Torah, and “eating of it” was reading and understanding the covenant of God (cf. Deuteronomy 8:3). For example, the apocryphal book of Sirach states, "‘He who eats of me will hunger still, he who drinks of me will thirst for more; he who obeys me will not be put to shame, he who serves me will never fail.’
It is very clear that Jesus referred to Himself as the Bread of Life and encouraged His followers to eat of His flesh in John 6. But we do not need to conclude that Jesus was teaching what the Catholics have referred to as transubstantiation. The Lord’s Supper / Christian communion / Holy Eucharist had not been instituted yet. Jesus did not institute the Holy Eucharist / Mass / Lord’s Supper until John chapter 13.
Whether the Catholic definition of Holy Eucharist is a “re-sacrifice” of Christ or a “re-offering” of Christ’s sacrifice, the concept is unbiblical.
Christ does not need to be re-sacrificed. Christ’s sacrifice does not need to be re-offered.
Hebrews 7:27 declares, "Unlike the other high priests, He (Jesus) does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people.
He sacrificed for their sins ONCE for all when He offered Himself." Similarly, 1 Peter 3:18 exclaims, "For Christ died for sins ONCE for all, the righteous for the unrighteous, t
