This season of Lent naturally has me thinking about the theme of sacrifice. I wondered when Jews gave up ritual sacrifice, and was interested to learn that the tradition was to eat the sacrificed animal - sharing it with the priest who no doubt got the filet, and to let the guts burn to ashes. In Christianity, Christ is the unblemished Lamb of God.
Those are the roots of Christ's instructions about what we now call "Communion." "This is my flesh, take of it and eat."
