Like TAKE AND EAT OF THIS, THIS IS MY BODY.....pay attention.
Did Jesus tell those present after the crowd dispersed that it is the spirit that quickeneth, the body profiteth nothing?
Don't call any man *Father*.
Don't forget, Jesus also said, "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."
IOW, He clarified that He did NOT mean literally eating literal flesh and blood, which would have violated many parts of the Law, which prohibits the consumption of blood but that He was talking about SPIRITUAL truth and spiritual eating, not physical.
