I’ll cut to the chase:
I ‘believe’ that whether a person believes the elements actually turns into Christ’s body and blood when consumed or they do not, makes absolutely NO difference as to their salvation.
Then I will accept that. These folks that blithely state beliefs as if they were facts are irritating.
Look at the Creeds - “I believe...”
Christianity is belief. If that is your belief, then I will respect that as your belief.
We are not saved by faith alone, so indeed it is possible to be saved despite one’s weak or even absent faith. However, I would not say that lack of faith, in this case, in the Holy Sacrament makes “absolutely no difference”. Poor, misshapen faith is a huge obstacle for salvation.
