Ordinary 20

The Blood was believe to contain the essence of life. When poured out in sacrifice if symbolize not holding anything back. The Law was very clear aabout not drinking the blood of any animal. It was poured out in sacrifice, it was sprinkled on the people, it was smeared on the door post, but was definely not drunk. The words of Jesus would have had a strong impact on his listeners. We might understand their revilement at the thought.

Eating human flesh was also a big NO-NO. They had probably heard preachers use strong images before. As long as it was an image, however distasteful, they might have gotten past it. But they could tell he was not using an image. What does this mean?

When taken out of context it doesn't make sense. When we see the whole picture, we understand what he was talking about and what the gift he was giving truly is.
