I don't know if you guys own bibles and just don't bother to read them or you just read the Catholic propaganda and think your smart teachers have something over on bible believers...
This is really the reason the followers left:
Joh 6:40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
Joh 6:41 The Jews then murmured at him, because he said, I am the bread which came down from heaven.
Joh 6:42 And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven?
Joh 6:62 What and if ye shall see the Son of man ascend up where he was before?
Joh 6:64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
Joh 6:65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
Joh 6:66 From that time many of his disciples went back, and walked no more with him.
It was the entire combination of things that led the disciples to leave...But mostly it was because they knew Jesus from a child...And now this little kid grows up and says he is God and will ascend to heaven...
Jesus knew they didn't believe...He knew they weren't going to believe...It wasn't a matter of Jesus trying to explain a single event...They didn't believe any of it...They were there for the food...
John 6:48 - "I am the bread of life.
John 6:49 - Your fathers ate the manna in the wilderness, and they died.
John 6:50 - This is the bread which comes down from heaven, that a man may eat of it and not die.
John 6:51 - I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh.”
John 6:52 - The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?”
John 6:53 - 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 you;
John 6:54 - he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.
John 6:55 - For my flesh is food indeed, and my blood is drink indeed.
John 6:56 - He who eats my flesh and drinks my blood abides in me, and I in him.
John 6:57 - As the living Father sent me, and I live because of the Father, so he who eats me will live because of me.
John 6:58 - This is the bread which came down from heaven, not such as the fathers ate and died; he who eats this bread will live for ever.”
[That's when many scornfully turned away from Jesus, and left Him.]
After this many of his disciples drew back and no longer went about with him.
