Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day. …. Then many of his disciples who were listening said, “This saying is hard; who can accept it?”
… I read that, for Jews of this time, drinking any blood would have been offensive and drinking the blood of a person would have been unthinkable. The Romans accussed the early christians of being cannibals :-). All of this relates to the eucharist and the idea of the real presence of the risen christ in the host and wine … stuff I don’t completely understand as I slept through much of my RCIA classes. There’s a poem attributed to Queen Elizabeth I about this idea and communion …
‘Twas God the Word that spake it,
He took the bread and brake it;
And what the Word did make it;
That I believe and take it.
