Definitely, it is a hard teaching. Many left Jesus Christ back then when he said it, and many leave him now. Jesus says we must eat his flesh, and drink his blood. Very hard teaching, indeed.
it appears that you may have misidentified the “hard teaching” of John 6 as Jesus’ statement that his flesh must be eaten for eternal life. Here’s where (in the NIV) the hard saying, together with Christ’s response is recorded:
Whoever eats my flesh and drinks my blood remains in me, and I in them. 57 Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. 58 This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.” 59 He said this while teaching in the synagogue in Capernaum.
60 On hearing it, many of his disciples said, “This is a** hard teaching**. Who can accept it?”
61 Aware that his disciples were grumbling about this, Jesus said to them, “Does this offend you? 62 Then what if you see the Son of Man ascend to where he was before! 63 The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit[e] and life. 64 Yet there are some of you who do not believe.” For Jesus had known from the beginning which of them did not believe and who would betray him. 65 He went on to say, “This is why I told you that no one can come to me unless the Father has enabled them.”
It is my position that the “hard teaching” is the teaching that
Jesus came down from heaven.
Here is what favours my identification over yours:
- The grumbling. The hard teaching is identified as the thing that the audience was grumbling about. Grumbling was mentioned earlier in the passage and in relation to Jesus’ claim to have come down from heaven and not with regard to his requirement to eat his flesh:
41 At this the Jews there began to grumble about him because he said, “I am the bread that came down from heaven.” 42 They said, “Is this not Jesus, the son of Joseph, whose father and mother we know? How can he now say, ‘I came down from heaven’?”
43 “Stop grumbling among yourselves,” Jesus answered. 44 “No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day.
As such, the established association for “grumbling” is Jesus’ claim to have come from heaven.
- The sequence. The sequence of Christ’s statements before the hard teaching is mentioned is:
a. Jesus talks about eating his flesh v.56
b. Jesus talks about coming from heaven v 58
c. Jesus talks about feeding on this bread v 58
As such, the mention of the hard teaching follows Jesus’s claim to have come from heaven more closely than it follows his mention of eating his flesh.
- Jesus’ answer Part 1. The start of Jesus’ response “Does this offend you? 62 Then what if you see the Son of Man ascend to where he was before!” fits far better with the hard teaching being Jesus’s claim to have come from heaven.
- Jesus’ answer Part 2. The end of Jesus’ response “This is why I told you that no one can come to me** unless the Father has enabled them**” relates back to verse 44 when Jesus tells the Jews to stop grumbling about his claim to have come down from heaven.
- Peter’s response. Peter’s response that identifies Jesus as the Holy One of God fits better with the hard teaching being Jesus’s claim to have come from heaven.
The Jews were still bothered about Christ’s origin a chapter later:
At that point some of the people of Jerusalem began to ask, “Isn’t this the man they are trying to kill? 26 Here he is, speaking publicly, and they are not saying a word to him. Have the authorities really concluded that he is the Messiah? 27
But we know where this man is from; when the Messiah comes, no one will know where he is from.”
Have you got anything that you think favors your interpretation? BTW, Eilrahc wanted ECF references……and in that regard Augustine claimed that Peter ate Christ’s flesh on the day of the Bread of Life discourse…before there was any Eucharist and w/o ingesting a thing. Augustine also had the OT saints eating the same thing and claimed Nicodemus would have eaten Christ flesh in John 3 had he made the same confession as Peter. Obviously, according to Augustine, to eat Christ’s flesh one did not need a priest’s consecration or a Eucharist…one needed belief.
