You conveniently overlook verse 26 in the passage you quote, which says clearly that it is BREAD when you eat it. And what is in the cup? Blood? No, it is clear: it is the NEW COVENANT IN Jesus’ blood.
You select verses, out of context, to support your pre-established doctrine. But Scripture is clear — even in the verses you quoted — that it is BREAD and WINE, powerful symbols of Jesus’ precious death.
I encourage us all to follow Scripture’s directive to do this “in remembrance of [Jesus].”
Of course, I won’t convince you. So you follow your denomination’s doctrines, and I’ll follow the plain teaching of Scripture.
Ah, that’s rich. Knock yourself out.
