Unless you have scriptural proof against the bread and wine miraculously being transformed into the Body and Blood of Christ based upon the faith of the believer, why does protestants even do it.
Do you believe that when Jesus was hosting the last supper, the disciples actually physically ate His flesh and drank His blood? Or were they eating a "symbol" of His flesh and blood?
1 Cor 11:23; For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed
took bread;
1 Cor 11:24; and when He had given thanks, He
broke it and said, “
This is My body, which is for you;
do this in remembrance of Me.”
1 Cor 11:25; In the same way
He took the cup also after supper, saying, “
This cup is the new covenant in My blood; do this, as often as you drink
it,
in remembrance of Me.”
1 Cor 11:26; For as often as you
eat this bread and drink the cup, you proclaim the Lord’s death until He comes.
1 Cor 11:27; Therefore whoever
eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord.
1 Cor 11:28; But a man must examine himself, and in so doing he is to eat of the bread and drink of the cup.
1 Cor 11:29; For he who eats and drinks, eats and drinks judgment to himself if he does not judge the body rightly.
1 Cor 11:30; For this reason many among you are weak and sick, and a number sleep.
1 Cor 11:31; But if we judged ourselves rightly, we would not be judged.
1 Cor 11:32; But when we are judged, we are disciplined by the Lord so that we will not be condemned along with the world.
1 Cor 11:33; So then, my brethren, when you come together to eat, wait for one another.
I would say the onus here, is to prove any of the disciples actually physically ate part of Jesus like cannibals, or actually drank His blood like vampires.
Also there was no priest present at this supper. Only Jesus the high priest. Why does that matter?
Jesus only had to be sacrificed once.
Rom 6:10; For the death that He died, He died to sin
once for all; but the life that He lives, He lives to God.
Heb 7:26 For it was fitting for us to have such a high priest, holy, innocent, undefiled, separated from sinners and exalted above the heavens;
Heb 7:27;
who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the
sins of the people, because this He did
once for all when He offered up Himself
Heb 10:10; By this will we have been sanctified through the offering of the body of Jesus Christ
once for all.
1 Pet 3:18; For Christ also died for sins
once for all,
the just for
the unjust, so that He might bring us to God, having been put to death in the flesh, but made alive in the spirit;
Jesus said do this "in remembrance" of Me. He never said keep sacrificing Me over and over again. Why does the RCC even have priests. The same reason the Jews of the OT did.
Lev 17:5; The reason is so that the sons of Israel may bring their sacrifices which they were sacrificing in the open field, that they may bring them in to the Lord, at the doorway of the tent of meeting
to the priest, and sacrifice them as sacrifices of peace offerings to the Lord.
Lev 17:6; The
priest shall sprinkle the blood on the altar of the Lord at the doorway of the tent of meeting, and offer up the fat in smoke as a soothing aroma to the Lord.
The priest were the ones who did the sacrifices. Priests are the ones who do "Mass" today for the same reason. They are sacrificing Jesus over and over again.
You can't have a sacrifice without blood. But they don't believe this is symbolic blood like the disciples partook of in the upper room. They believe it literally becomes Jesus's blood.
I guess Jesus's sacrifice "once for all" wasn't good enough?
