Or maybe, just maybe… what He drank at the Last Supper was actually His Body, Blood, Soul and Divinity.
that is immaterial as to the question of Jesus saying He would not drink wine until…
Actually upon reading Writ He does not qualify it with the circumstance…kind of says won’t drink it again till they all be together. So now did He drink at the cross is the question. I think two gospels say vinegar and one wine , and says he tasted “vinegar” it but did
not drink, and was he offered drink more than once? Tough to say if He drank…doubt it, twas poison(gall) mixed with wine/vinegar
“They put gall in my food and gave me vinegar for my thirst.” Psalm 69:21…Some believe He did accept vinegar but only at the last moment, having refused before, and to fulfill scripture.
So whether Jesus drank wine again or not , He called it wine
after consecration. Not sure it messes anybody’s communion view, for the appearance is still wine, the symbol is still wine.
I have read some Catholic literature for mass attendants on how to clean wine from Mass linens , either table cloths and the "towels’ or on any vestments. They were called “wine” stains.
