Here's a short FGO I presented a few months ago:
"I just noticed in Palm Sunday's Gospel reading from Luke, that at the Last Supper Jesus didn't eat or drink after the words of Consecration:
"And when the hour came, he sat at table, and the
apostles with him. 15* And he said to them, "I have earnestly desired
to eat this passover with you before I suffer; 16* for I tell you I
shall not eat it * until it is fulfilled in the kingdom of God." 17*
And he took a cup, and when he had given thanks he said, "Take this, and
divide it among yourselves; 18* for I tell you that from now on I
shall not drink of the fruit of the vine until the kingdom of God
comes." 19* And he took bread, and when he had given thanks he broke it
and gave it to them, saying, "This is my body which is given for you.
Do this in remembrance of me." 20 And likewise the cup after supper,
saying, "This cup which is poured out for you is the new covenant in my
Nor in Matthew:
"When it was evening, he sat at table
twelve disciples... Now as they were eating, Jesus took bread, and
blessed, and broke
it, and gave it to the disciples and said, "Take, eat; this is my
body." 27 And he took a cup, and when he had given thanks he gave it to
them, saying, "Drink of it, all of you; 28* for this is my blood of the
covenant, which is poured out for many for the forgiveness of sins.
29 I tell you I shall not drink again of this fruit of the vine until
that day when I drink it new with you in my Father's kingdom."
Nor in Mark:
"And as they were eating, he took bread, and blessed, and broke
it, and gave it to them, and said, "Take; this is my body." 23* And he
took a cup, and when he had given thanks he gave it to them, and they
all drank of it. 24* And he said to them, "This is my blood of the
covenant, * which is poured out for many. 25 Truly, I say to you, I
shall not drink again of the fruit of the vine until that day when I
drink it new in the
kingdom of God."
Having thought about this for several minutes (!), I believe this points to
Transubstantiation. If Jesus were speaking symbolically when he said
"This is my body...this is my blood," then why not share in the eating
and drinking along with the Apostles? If nothing else, it would clarify
that this bread and wine were no different from any they had consumed
earlier in the evening; lest anyone erroneously suppose Jesus was
speaking literally on this night, and also the day after the Loaves and
Fishes miracle (John 6).
On the other hand, if Jesus had indeed
transformed the elements into his own flesh and blood, then it would be
appropriate that he not partake in consuming himself.
