According to you, at the time of the Last Supper, drinking blood was still a sin.
Therefore, Jesus could not have given his REAL blood to drink, because that would be a sin.
So, when Jesus SAID, “Take this and drink; this is the chalice of my blood in the new covenant...”—He was instructing the apostles to do something that SYMBOLIZED the commission of a sin.
Tell me where in the gospel Jesus said it was okay to commit adultery SYMBOLICALLY. Show me where in the gospel Jesus said it’s okay to worship idols SYMBOLICALLY. Show me where Jesus said it was okay to lie SYMBOLICALLY.
Can I show where He said, "Go and sin no more."?
Not any more then Ezekiel was symbolically eating the physical scroll. I don't think it "symbolizes" anything. Christ said to do it as a "remembrance" just as the passover meal was a "remembrance".
It's God's word that feeds us. Jesus is the word. As Ezekiel did we "eat" as in "take in" or "internalize" the word of God. He didn't literally eat the physical scroll. As Ezekiel we feast on the information which feeds our souls. Just as manna in the desert sustained the Israelites so God's word sustains us today.
Christ's death on that cross and the shedding of His blood is the atonement for our sins. We are redeemed by the shed blood of Christ (1 Peter 1:18-19). Peter wrote that election is "unto obedience and sprinkling of the blood of Jesus Christ" (1 Pet. 1:2). Do Catholics also sprinkle real blood? Scripture speaks of the blood of Christ nearly three times as often as it mentions the cross, and five times more often than it refers to the death of Christ. It refers to atonement. To eat His flesh and to drink His blood means to believe on Him and "eat" the words and internalize them.
\ Just as the Israelites commemorated or remembered the passover so we commemorate or remember the broken body and shed blood of Christ for our atonement. Christ said "this do in remembrance of me". He didn't say "repeat doing this to me".
Christ also said He would again drink of the vine in the kingdom of God (Mark 14:25). Would you say He is once again going to drink the blood?
As I have said often. Jesus lived as an observant Jew, keeping the Torah or Laws of Moses and teaching others to do the same. Jews were strictly forbidden to consume blood or even to eat meat that had not had the blood properly drained and removed (Lev. 7:26-27). Had He condoned the eating of blood and done so at the last supper He would have been breaking the law and would have been unworthy to be the forever atonement for our sins.
Now, you love to ask questions but haven't answered mine. We know that death is the result of sin. Christ died for our sins having "taken our sins upon Him". Whose sins did Mary die for?
