John 6:35-71 - The Eucharist is promised.
Matthew 26:26, Mark 14:22, Luke 22:17 - The institution of the Eucharist.
1 Corinthians 10:16 - The Eucharist is a participation of Christ's body and blood.
1 Corinthians 11:23-29 - Receiving unworthy, guilty of his body and blood.
Exodus 12:8, 46 - Pascal lamb had to be eaten.
John 1:29 - Jesus called "lamb of God".
1 Corinthians 5:7 - Jesus called the "pascal lamb" who has been sacrificed.
John 4:31-34, Matthew 16:5-12 - Jesus speaking symbolically about food. We can compare these verses to the verses where he his speaking about his body and blood as food.
1 Corinthians 2:14-3:4 - Explains what "the flesh" means in (John 6:63.)
Christ, knowing what it meant to his Jewish followers to ask them to eat blood, would not have asked them to eat his flesh and blood symbolically, he was serious about this teaching. He knew what he risked upon reveal this "hard saying" (John 6:60)
He knew the Jews would take offense at it, as they did in (John 6:52.) Yet after this he only intensified his language causing a great schism among his followers, many no longer followed him after this (John 6:66.)
John 6:67-68 - Jesus says to the twelve, "Do you want to go away as well"? Simon Peter answered him saying, "Lord, to whom shall we go? You have the words of eternal life, and we have believed and have come to know, that you are the Holy one of God."
Peter and the twelve didn't understand how Christ was going to give us his flesh and blood for food. But they believed his words with faith and trusted that he knew what he was doing.
Notice that Judas did not have the integrity to leave like the other followers, but after the teaching of the Eucharist he set out to betray Jesus, and Christ new this (John 6:70-71.)
Will we be like the disbelievers who walked away, like Judas who betrayed him, or like Peter and the twelve who believed?
If Jesus were merely speaking symbolically, he could easily have called the other disciples back and explained that he wasn’t speaking literally. He did not. He allowed the schism and lost many followers over it.
Christ used water, spittle, bread, wine, his own body and blood to minister to those who needed him. Everything Christ did was spiritual as well as physical.
Since Jesus is God, if he said that the bread and wine becomes his body and blood, then those who acknowledge his divinity should have no difficulty believing it like the Twelve. The Eucharist is certainly no more extraordinary than his Incarnation or anything else he did!
On the road to Emmaus after they found the tomb empty. In (Luke 24:13-25) the two men Cleopas and another one were met by Jesus.
They experienced with Christ the liturgy of the word (his preaching on the scriptures) and then the "breaking of the bread." We are told in Luke they did not recognize him until the "breaking of the bread." (Luke 24:35)
Will we recognized Christ in the breaking of the bread?
The sacrifice of the mass is not a new sacrifice. The Church does not kill Christ again. Christ died once, he offered his body for our sins once and for all on the cross.
Therefore when we participate in the body and blood of Christ in the Eucharist we are taken back to that same once and for all sacrifice of Christ on the cross.
We are transported to Calvary and partake of his crucified flesh that he offered up as the Lamb of God who takes away the sins of the world, in the new Passover under the New Covenant.
Up to the 16th century virtually all Christians believed that the bread and wine truly becomes the body and blood of Christ. That’s a long time. The largest and oldest Christian Church still does as do the Orthodox churches.
So there has to be something credible about it.
The Eucharist is "the source and summit of the Christian life." (CCC 1324)
“The Eucharist is not a thing. It is not a dead object. It is Christ and He is fully alive. Receiving Him with this awareness, we become more fully alive, so that we can say with St. Paul, ‘It is no longer I who live, but Christ who lives in me.’ “
