What Christ gives us is quite explicit if his own words are interpreted according to their Aramaic meaning. The expression 'This is my Body' means this is myself.

That calls for an altruistic detachment from oneself and a mysterious sympathy with others which is felt even before they open their mouths. Only the person who has also a gift for affection can have a true sense of humor. A good laugh is a sign of love; it may be said to give us a glimpse of, or a first lesson in, the love that God bears for every one of us.
