The whole bread of life discourse should be looked at as a whole so that the interpretation is consistent with the whole. Jesus just doesn’t start when talks about eating His body and drinking His blood. It must also be consitent with the rest of Scripture.
In the Bread of Life discourse in John 6 Jesus says a number of things.
“I am the living bread that came down out of heaven; if anyone eats of this bread, he will live forever; and the bread also which I will give for the life of the world is My flesh.”
(John 6:51 NASB)
"He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day.
(John 6:54 NASB)
These are unequivocal promises that anyone who eats His flesh and drinks His blood will have eternal life. There are no qualifications put on the promises; no requirements of faith or belief are given and no requirement is made that one partake in a worthy manner. If transubstantiation is true, then according to these promises all one would have to do to have eternal life is go to a Catholic Mass and partake of the Eucharist. It would not matter that this was done illicitly or without any faith at all; the requirements of the promises would be met.
Jesus says more about eating His flesh and drinking His blood.
So Jesus said to them, "Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves.
(John 6:53 NASB)
Here another unequivocal statement is made telling us that we must eat His flesh and drink His blood. Unless we do so, nothing else can help us because no exceptions are given to the requirement. Taken together, if interpreted literally, these passages would mean that we could receive eternal life if and only if we eat Jesus’ flesh and drink His blood.
Earlier in John 6 Jesus makes other unequivocal promises.
“For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day.”
(John 6:40 NASB)
"Truly, truly, I say to you, he who believes has eternal life.
(John 6:47 NASB)
In these promises Jesus tells us that if we believe in Him we will have eternal life. Paul also talks about the Lord’s Supper.
Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord. But a man must examine himself, and in so doing he is to eat of the bread and drink of the cup. For he who eats and drinks, eats and drinks judgment to himself if he does not judge the body rightly. For this reason many among you are weak and sick, and a number sleep. But if we judged ourselves rightly, we would not be judged. But when we are judged, we are disciplined by the Lord so that we will not be condemned along with the world.
(1 Corinthians 11:27-32 NASB)
In this passage Paul tells us that we must partake in a worthy manner yet Jesus puts no such requirement in his statement. If Jesus’ statements about eating His flesh and drinking His blood are taken literally then those statements contradict what both Jesus and Paul say elsewhere. However, Scripture cannot contradict itself so Jesus must not be speaking literally of eating His flesh and drinking His blood. What then does Jesus mean?
It can be seen that He makes two very similar statements, “everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day." and "He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day. “ It is apparent that Jesus is speaking figuratively and that eating His flesh and drinking His blood is equivalent to believing in Him. Is such figurative speaking consistent with Jesus’ other teaching?
It can be seen that throughout John’s Gospel Jesus does frequently speak figuratively. In fact, He says so Himself.
"These things I have spoken to you in figurative language; an hour is coming when I will no longer speak to you in figurative language, but will tell you plainly of the Father.
(John 16:25 NASB)
Another characteristic of Jesus’ teaching in John’s gospel is the repeated use of the phrase “I am the”.
- The bread of life.
Jesus said to them, "I am the bread of life; he who comes to Me will not hunger, and he who believes in Me will never thirst.
(John 6:35 NASB)
- The light of the world
Then Jesus again spoke to them, saying, “I am the Light of the world; he who follows Me will not walk in the darkness, but will have the Light of life.”
(John 8:12 NASB)
- The door of the sheep
So Jesus said to them again, "Truly, truly, I say to you, I am the door of the sheep.
(John 10:7 NASB)
- The good shepherd
"I am the good shepherd; the good shepherd lays down His life for the sheep.
(John 10:11 NASB)
- The resurrection and the life
Jesus said to her, “I am the resurrection and the life; he who believes in Me will live even if he dies, and everyone who lives and believes in Me will never die. Do you believe this?”
(John 11:25-26 NASB)
- The way, the truth and the life
Jesus *said to him, "I am the way, and the truth, and the life; no one comes to the Father but through Me.
(John 14:6 NASB)
- The true vine
"I am the true vine, and My Father is the vinedresser.
(John 15:1 NASB)
It is clear that many of these statements are figurative since Jesus is not literally a door or a vine. The statement “I am the bread of life” fits into the pattern that Jesus established of speaking about Himself figuratively.
