[Elsie]

I Cor. 11:24 And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. 25 After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. 26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.

Everything bolded was in the PASSOVER meal: ONCE a year.

The ONLY thing Christ was doing, was EXPLAINING just what the ELEMENTS of the meal represented.

There was NO meal involved went John the Baptist announced:

"BEHOLD! The LAMB of GOD..." yet he, too, was refering to the PASSOVER 'lamb'.

The problem with you analogy is that the New Testament churches were observing the Lord’s Supper long after Christ ascended into heaven. There are also accounts that it was observed on a weekly basis. Given that information we can conclude that the Apostles understood that it was not just a Passover meal.
