Jesus is the Son of God, not a saint,
He told his Apostles to do this in remembrance of him.
The Catholics say that the wine actually turns into Christ`s blood so could be called the blood of the saints since they say that the apostles also believed that the wine actually turned into blood.
It has nothing to do with actual blood, it has to do with being drunk on false doctrine.
“The Catholics say that the wine actually turns into Christ`s blood so could be called the blood of the saints since they say that the apostles also believed that the wine actually turned into blood.”
Do Catholics call it “the blood of saints”? No. Does the Bible say that the Catholic eucharist is the “blood of the saints”? No. Only you are saying that it might be.
In fact, the Bible uses similar language many times, and it is always to refer to the blood of murdered people, which God uses as a symbol of unfulfilled vengeance. That vengeance is exactly the topic of Chapter 18, finally being fulfilled, so it is no wonder that the symbol appears there. You really have to stretch the boundaries of reason to try to make it appear to represent anything else.
