Here is a very interesting article.
Cutting to the chase, it says that Jesus did not say to drink his blood(wine) and eat his body(bread), at the Last Supper. In other words, Jesus’ Communion commandment was a myth. He did not tell us to do that.
Paul is the first one to write that Jesus said to eat the bread and drink the wine. Paul claimed that Jesus told him that through revelation.
In their Gospels, Matthew, Mark and Luke, repeated Paul’s account almost word for word. Matthew, Mark or Luke did not claim to be Apostles or claim to have known Jesus. There is no evidence they did. They got their Last Supper story from reading Paul, who wrote years before they did.
John, on the other hand, was an Apostle and obviously did know Jesus. He was at the Last Supper. In his Gospel, John recounts the Last Supper, but makes no mention of Jesus passing around bread and wine and saying it was his body and blood.
John was also familiar with Paul’s writings. In his own way he disputed Paul’s account.
Also, Jesus and the Apostles were devout Jews. Eating a body and drinking blood was anathema to Jewish scripture and culture.
