Since before the Last Supper, disciples of Christ have taken seriously his words that he is present and able to provide us spiritual nourishment with his body and blood in the form of bread and wine. Catholics accept the mystery of this, that Christ is truly present, body, blood, soul, and divinity. Just as a mother physically nourishes her child with her living body without any decimation of self, Christ nourishes us without any decimation of his body. We honor, thank, and glorify Christ for the gift and nourishment he provides us. Christ spoke the words of everlasting life. Many will not walk away from him, no matter how hard the words.
No, according to the gospel of John Jesus made it clear that his claim that one must eat his flesh and drink his blood to receive eternal life, the saying that many could not stomach, was a metaphor for the words that he spoke, his teaching about the figurative nature and hidden subjects of the divine commands that must be understood before it is even possible to receive the promise of eternal life fulfilled in this world. " The spirit alone gives life; the flesh is of no avail.
The words that I have spoken to you are both spirit and life." John 6:63
when Jesus asked his closest disciples if they were going to leave him too, after he explained himself, Simon Peter replied, "Lord, to whom shall we go?
You words are words of eternal life. We have faith and know that you are the Holy One of God." John 6:68.
Words and teaching from above, like manna from heaven, the food of angels, was already an established metaphor in Judaism, that only studied Jews would have understood.
"The days are coming," declares the Sovereign LORD, "when I will send a famine through the land-- not a famine of food or a thirst for water,
but a famine of hearing the words of the LORD. Amos 8:11
"Come! Every one who thirsts, come to the waters; And you who have no money come, buy and eat. Come, buy wine and milk without money and without cost. "Why do you spend money for what is not bread, And your wages for what does not satisfy?
Listen carefully to Me, and eat what is good, And delight yourself in abundance. "
Incline your ear and come to Me. Listen, that you may live; And I will make an everlasting covenant with you, According to the faithful mercies shown to David. Isaiah 55:2-…
What the disciples confirmed to believe was that the words that Jesus spoke that teach the way to understand and apply the law that leads to eternal life is what gives life. They never claimed to believe anything about bread and wine being what he meant by flesh and blood.
In fact it is no small point that during the last supper according to the gospel of John, no one was given bread or wine except Judas, as way for Jesus to covertly identify his betrayer to the others, and "as soon as Judas received the bread, Satan entered him." John 13:27
If you have ears to hear, then hear.
