I mean, He LITERALLY said that it's His body and blood and that we should do this in remembrance of Him.
Everyone is cherry-picking what "literally" means, IMO, otherwise, we would all agree on everything.
I'm convinced that believing it _all_ literally is heroic virtue and only a small number of people have ever fully achieved it, but that doesn't mean that lots of other people weren't as faithful and aren't also spending eternity with Christ.
These are not things that perfectly align, or that humans can even accurately judge.
