Eat Jesus’ flesh/ drink His blood??

Jesus’ graphic picture about eating His flesh and drinking His blood is indeed crazy at first glance.Not only is it impossible to do, but repulsive to most everyone.

Context will help us understand what He is saying. As we consider everything that Jesus said and did in John 6, the meaning of His words becomes clearer.

Earlier in the chapter, Jesus fed the 5,000 (John 6:1–13). The next day, the same multitudes continued to follow Him, wanting another meal. Jesus pointed out their short sightedness: they were only seeking physical bread, not spiritual bread.Jesus try’s to turn their perspective away from physical sustenance to their true need, which was spiritual.

This contrast between physical food and spiritual food sets the clear stage for Jesus’ statement that we must eat His flesh and drink His blood. Jesus explains that it is not physical bread that the world needs, but spiritual bread. Jesus clearly identifies Himself 3 times as that spiritual bread (John 6:35, 48, 51). 

Jesus then compares and contrasts Himself to the manna that the Jews had eaten in the time of Moses: (John 6:49–50). Like manna, Jesus came down from heaven; and, like manna, Jesus gives life. Unlike manna however the life Jesus gives lasts for eternity (verse 58). In this way, Jesus is greater than Moses (see Hebrews 3:3).

Those who misunderstood Jesus and were offended by His talk about eating His flesh and drinking His blood were stuck in a purely physical mindset, totally ignoring the things of the Spirit. 

They were concerned with just getting another physical meal, so Jesus uses the realm of the physical to teach a vital spiritual truth. Those who couldn’t make the jump from the physical to the spiritual turned their backs on Jesus and walked away (verse 66).

The Catholic cult believe,s that the bread and wine of communion are somehow magically transformed into Jesus’ actual flesh and blood because they they want to add their own spin and tradition to scripture.These tradition oriented ideas are called transubstantiation per the Catholic cult magisterium CCC 1376 ...

“The Council of Trent summarizes the Catholic faith by declaring: "Because Christ our Redeemer said that it was truly his body that he was offering under the species of bread, it has always been the conviction of the Church of God, and this holy Council now declares again, that by the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood. This change the holy Catholic Church has fittingly and properly called transubstantiation."
