Not IF read in CONTEXT.
The Bread of Life Discourse is about having faith in Him....not eating flesh and blood. Romans are making the same error the unbelieving Jews did.
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? 62What then if you see the Son of Man ascending to where He was before?
63It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life.
64But 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.
[His prior statement is what caused them to walk away...not the discussion of eating/drinking flesh and blood]
67So Jesus said to the twelve, You do not want to go away also, do you?
68Simon Peter answered Him, Lord, to whom shall we go? You have words of eternal life.
69We have believed and have come to know that You are the Holy One of God. [Peter and the disciples have correctly heard and understood Jesus. Go back to v40.]
40For 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.
This is the clear consistent teaching John has recorded throughout His Gospel...and that of the NT as well.
We have eternal life through believing in Jesus as Peter replied back to His question.
Notice Peter did not say "we have eaten your flesh and drunk your blood." He professed belief in Christ. That is an important distinction and illustrates that Peter and the disciples understood the message.
Yes, “context,” that magic word used by Protestants to say that what the Bible says does not actually mean what the Bible actually says.
