Interesting article but its very hard to follow. You need to do some proofreading and editing. Pushing many of your inline quotations to the footnotes would be a major help.
Your thought process seems to be:
>1: The last supper can be established as a passover meal
>2: The passover meal was more than memorial
>3: Taking the Lord's supper provides a real presence
You discuss eschatological symbolism and I can only tell the objective is to support the last supper as related to passover.
I do not see 2 proven in the article. I also see the use of language that zwinglian memorialists can happily affirm which you're using to describe real presence.
