Communion: comes from "con union," with means "union with." What you posted above is the Protestant conception of "the breaking of the bread." The Catholic conception comes from the fact that in John 6, some of Christ's disciples are scandalized by His words concerning His Flesh and Blood. We think the Last Supper is the fulfillment of Christ's words in this Scripture passage. For He said, "Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you."
Oh, by the way, your painting of us as "Pharisees" is libelous.
Ha! I think that the pharisees said the same thing to our Savior ... thank you for the elevation!
