It may do that, but the greek construct is no different than numerous other passages. For example in Matthew 8:9 the soldier speaks of his servant in the same fashion. This is common greek grammar which has no bearing on whether or not ALL future "breads" are also the body of Christ.
2) Also notice the the clause "This do in remembrance of me." He is telling them to repeat this event. Now this is where you say well it must be symbolic! But that is where you are woefully wrong. The word "remembrance" has special significance to the Jewish community. They were celebrating the Passover, the precursor to the Exodus. Jewish people consider the performance of the Passover ritual as an actual participation in the passover event. It is eternally present in the participation of that event.
Actually the word translated "remembrance" does have significance. That's because it would bring to their mind a "memorial".
In the LXX, the greek version of the old testament in common use at the time of Christ, the word (transliterated) "anamnēsis" (Strongs G364) is used in the following verses:
Num 10:10 Also in the day of your gladness, in your appointed feasts, and at the beginning of your months, you shall blow the trumpets over your burnt offerings and over the sacrifices of your peace offerings; and they shall be a memorial for you before your God: I am the LORD your God."
Lev 24:7 And you shall put pure frankincense on each row, that it may be on the bread for a memorial, an offering made by fire to the LORD.
Now that word translated "memorial" in the LXX is the same word translated "remembrance" in the nt verses Luke 22:19 and 1 Corinthians 11:24 and 25.
Now here's what's significant: In Leviticus 24:7 what was happening was that the frankincense was being burned or offered in place of the shewbread. The Complete Jewish Bible translates:
(CJB) Put frankincense with each row to be an offering made by fire to Adonai in place of the bread and as a reminder of it.
So yeah, the actual greek indicates that the bread and wine were meant to represent and remind us of the blood and body of Christ...said as the burned incense was representative of the showbread.
Yeah like I said, Go to AskMoses.com and ask them about my interpretation/ understanding. You will find that I am spot on. Nice try at leaving that part of my quote out.
