First, you show an ignorance for "blood" and what it represents. His blood washes our conscience (Heb. 9:14) and our conscience is not tangible but spiritual. His "blood" shed for us simply means he offered up a sinless life as that is what the blood represents. If he had only shed blood from the flogging it would be worthless. If he only shed blood from the crown of thorns it would be worthless. In sacrificial terminology and meaning the "shedding of blood" means DEATH cessation of life and the life is worthless unless it was a life without blot or blemish - sinless life that was lived from birth to death.
So when Jesus says "this is my blood" it is metaphorical, representing HIS LIFE that was offered up. Your perverted abusive use of the Lord's Supper denies the sufficency of his blood - meaning HIS LIFE between birth and death - as it is that LIFE that satisfied once and for all, all the demands of the law against the sinner - paid in full. However, the Roman Catholic sacrilegious abuse of the Supper by claiming the cup is his LITERAL blood repudiates the whole gospel of Christ by denying over and over again the sufficiency of Christ's life to satisfy all the Law's demands against the sinner. You don't even have an inkling of what "the blood" of Christ means or you wouldn't abuse it by your false gospel ungodly sacraments.
Well I would challenge your opinion with Paul's own perversion.
1 Corinthians 11
27Wherefore whosoever shall eat this bread, and drink
this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
28But let a man examine himself, and so let him eat of
that bread, and drink of
that cup.
29For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
Key point is not discerning the Lord's body. That means you don't recognize it as his body.
If I believed what you believed I would have to stand and object to Paul here, citing that Paul is denying the sufficiency of the TRUE body and TRUE blood and my worthiness to this metaphorical fake holds no ground to the real deal that happened on the cross.
But Paul says if I don't eat the bread and drink this cup worthily im guilty of the real body and blood of the lord.
The only thing I would discern is this is metaphorical symbolic fake and not his body.
29For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
That is plain and simple. Taking your belief I am not discerning the Lord's body. When I'm eating the bread and wine I am discerning this is not really your body.
Paul can answer "shall be guilty of the body and blood of the Lord."
I am not guilty of the actual body and blood of the lord. No that's just some "graven image".
Here is me adopting your view:
1 corinthians10
16Is not the cup of blessing which we bless a sharing in the blood of Christ? Is not the bread which we break a sharing in the body of Christ?
No its not. These are just symbols. I had my communion and sharing when Jesus died on the cross. This is not the actual sharing in the body and blood of Jesus.
Bib, tell Paul he is wrong.
