If He was speaking figuratively then why did John 6:66 take place? People don’t usually leave when someone speak figuratively.
They did in this case as Jesus told them there were some who did not believe in Him. It is not the first time, and not the last time, that people have heard the simple message of the gospel regarding faith in Christ and have walked away.
59 These things He said in the synagogue as He taught in Capernaum.
60Therefore many of His disciples, when they heard this said, “This is a difficult statement; who can listen to it?” 61But Jesus, conscious that His disciples grumbled at this, said to them, “Does this cause you to stumble? 62“What then if you see the Son of Man ascending to where He was before? 63“It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life. 64“But there are some of you who do not believe.” For Jesus knew from the beginning who they were who did not believe, and who it was that would betray Him. 65And He was saying, “For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father.” 66As a result of this many of His disciples withdrew and were not walking with Him anymore.
They leave because they don't understand spiritual truths.
Jesus also said.....
John 6:63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life
The flesh is no help at all. Eating Jesus flesh isn't going to do anything for anyone.
: Please read the text, you will see that the discourse on "the bread" was past.. . 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.”
66 From this time many of his disciples turned back and no longer followed him.
They walked away , but the issue was not "eating" his flesh..it was His claim of deity >
They did not like hearing that salvation had to be given them and much like the manna in the desert, it was totally a gift of the Father. They could not do anything on their own to earn it, they only had access to it by faith ( remember the Jews could only gather enough manna for the one days meals, and for 2 days on the day before the sabbath, they had to have faith in God to provide what was necessary for their life) . The idea that salvation was all of God and not found in law keeping was blasphemy to the law oriented Jews that felt their salvation was based on their will, their law keeping etc
To make an attempt to make this a teaching on the Lords supper misses the mark. Christ was still alive and in His flesh and he was, by your reckoning , telling them to do something they could not do because the Lords Supper had not been instituted yet,it is a spiritual eating and drinking that is here spoken of, not a sacramental.
This was clearly a metaphorical teaching to Jews looking for a Physical savior like Moses, and for physical bread to meet their physical hunger. Jesus always used symbols that the Jews understood to make spiritual points.
Notice Peters response when asked if he wanted to leave too...
68 Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life. 69 We have come to believe and to know that you are the Holy One of God.”
Peter did not ask for that BREAD.. ... He said Jesus had the WORDS of eternal life.. not the bread.. he affirmed the deity of Christ
