If someone asks you to take something, what do you do? Do you reach out, or do you wait for them to put it in your hand, or even on your tongue?
Jesus said, “Take, eat” (Labete phagete in Matthew’s Greek).
Some hope that fewer Catholics will do that, and will instead opt to open their mouths and receive Communion on the tongue as in older times (a practice a senior Vatican official is suggesting should once again be the universal practice). Fr. John Z. reports and comments; see also the discussion at Commonweal.
Those Catholics who advocate for Communion being received by the laity only on the tongue and kneeling (clerics would still get to receive in the hand) stress the reality of the Eucharist as the body and blood of Christ.
Let’s not argue with the latter point for the moment.
What was Jesus’ attitude towards his physical body? “Put your finger here; see my hands. Reach out your hand and put it into my side.” Go ahead. Touch me. I’m not a ghost.
Why should he now be untouchable?
Do some Catholics really think this is what happened at the Last Supper?
