" Many mystics and liberation theologians have further recognized that inviting us to drink wine as his blood is an invitation to live in bodily solidarity “with the blood of every person whose blood has been unjustly shed on this earth, from the blood of Abel the Holy to the blood of Zechariah” (Matthew 23:35). These are the first and last murders noted in the Hebrew Bible. In the act of drinking the blood of Christ at this Holy Meal, you are consciously uniting yourself with all unjust suffering in the world, from the beginning of time till its end. "
