6:56 This was a shocking message--to eat flesh and drink blood sounded cannibalistic. The idea of drinking any blood, let alone human blood, was repugnant to the religious leaders because the law forbade it (Leviticus 17:10, 11). Jesus was not talking about literal blood, of course. He was saying that his life had to become their own, but they could not accept this concept. The apostle Paul later used the body and blood imagery in talking about communion (see 1 Corinthians 11:23-26).
