Just the opinion of non believers....
John 6
The Jews quarreled among themselves, saying, “How can this man give us [his] flesh to eat?” 53Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. 54Whoever eats* my flesh and drinks my blood has eternal life, and I will raise him on the last day. 55For my flesh is true food, and my blood is true drink. 56Whoever eats my flesh and drinks my blood remains in me and I in him.
The Scriptures often speak of the “authority” with which Jesus taught. For example, Scripture says of Jesus, he taught as one who had authority, and not as their teachers of the law (Mat 7:29). Indeed, the teachers of Jesus’ time played it safe, quoting only reputable authorities in a wooden sort of way. Jesus, however, taught with authority.
What say you to the questions?
The teachers who Jesus condemned for their tradition had bound up the Jews in a hopeless web of rules which were impossible to keep....ummmm....sounds like a group we know today.
