2. Jesus states: Truly, Truly, I tell you, if you do not eat the flesh of the Son of man and drink his blood, you have no life in you. Anyone who does eat my flesh and drink my blood has eternal life, and I shall raise him up on the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood lives in me and I live in that person. [John 6:53-56].
2. For the pious Jew, cannibalism is strictly forbidden by the Mosaic Law. Second, if they drink the blood of any living creature, they could be considered as cut off from their people because life(blood) belongs to God.
3. Blood is drunk as food by certain peoples ([eg] Massai) or collected and cooked in preparations such a blood sausage.
