I think that this...

"take of this and eat it for it is my body"? What does he mean? It's his body and therefore it's obvious that they should eat it? What kind of nonsense is that?
...is related to the old tradition of sacrificing a lamb or other animal to the alter of God and as such eating his "flesh" and "blood" is related to this old practice. Supposedly Jesus is acting as the "Lamb of God", and this may negate the necessity of those ritual sacrifices as he is now the only sacrifice worthy for God. I'm no expert on this but I do believe i have heard this told before.
