There is no more need for sacrifice. Christ's sacrifice was sufficient and finished on the cross.That's the Catholic Church's teaching.
REDTETRAHEDRON: That's the Catholic Church's teaching.
Would that were true.
But that is not what the Roman Catholic church teaches since Rome maintains there is no salvation outside those who offer and partake of the Eucharist on a continuing, "perpetual" basis. There is so much error within the RCC understanding of the Lord's Supper it is difficult to narrow it down...
1324 The Eucharist is "the source and summit of the Christian life." 1377 The Eucharistic presence of Christ begins at the moment of the consecration and endures as long as the Eucharistic species subsist. Christ is present whole and entire in each of the species and whole and entire in each of their parts, in such a way that the breaking of the bread does not divide Christ. 1382 The Mass is at the same time, and inseparably, the sacrificial memorial in which the sacrifice of the cross is perpetuated and the sacred banquet of communion with the Lord's body and blood... 1383 The altar, around which the Church is gathered in the celebration of the Eucharist, represents the two aspects of the same mystery: the altar of the sacrifice and the table of the Lord. This is all the more so since the Christian altar is the symbol of Christ himself, present in the midst of the assembly of his faithful, both as the victim offered for our reconciliation and as food from heaven who is giving himself to us. 1323 "At the Last Supper, on the night he was betrayed, our Savior instituted the Eucharistic sacrifice of his Body and Blood. This he did in order to perpetuate the sacrifice of the cross throughout the ages until he should come again, and so to entrust to his beloved Spouse, the Church, a memorial of his death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet 'in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us.'"
Again, the "victim" has already been offered and accepted by God as fulfilling the Scriptures and paying in full for all the sins of the elect.
The altar is not Christ. Christ is Christ who now sits at the right hand of God the Father in heaven.
The sacrifice of the cross is not ongoing and being "perpetuated;" it is finished (John 19:30.)
The sacrifice of the cross is a historical event. It occurred once almost 2,000 years ago outside Jerusalem (Mark 15:21-41.)
Christ cannot be made present in His death for He has risen and is "alive forevermore." (Rev. 1:17,18; Romans 6:9,10.)
And as Hebrews 9:24-28 tells us, Christ presented the sacrifice of Himself to the Father "once at the consummation of the ages."
No "other Christ" has the ability to change bread and wine into the very body and blood of Jesus Christ. That opinion is wizardly alchemy and something the Bible-believing Christian should reject as "vain jangling," or worse.
