We aren't the ones burdened with the man-made invention of YOPIOS.
Not only that, would be rather difficult for us to literally eat His flesh, since He was resurrected and lives today.
Would that because He somehow lacks the ability to be omnipresent? Did He LIE when He said, "This is My Body"? Did He LIE when He said, "For where there are two or three gathered together in my name, there am I in the midst of them"?
The problem with criticizing the YOPIOS position, is that most of what non-Catholics believe is not a matter of personal interpretation. There are millions, if not hundreds of millions of Christians who do not accept transubstantiation, but rather that the bread and cup are symbolic and the ceremony is for remembrance only, not a re-enactment of the sacrifice ever time communion is celebrated.
There are also millions of believers who accept the doctrine of justified by grace alone, baptism as being symbolic, as well as other doctrine that Catholics like to write off as YOPIOS.
When it comes to issues like drinking and dancing, yeah, there’s some wiggle room for personal interpretation, if you consider it a sin, then for you it is a sin to participate, but as for the deity of Christ, the virgin birth, the Incarnation, the sinless life of Christ, His atonement, all the things that are considered critical for salvation, most major denominations are pretty close.
I can go into a Baptist Church or a pentecostal one and find believers there and have fellowship with them, even if I disagree with their stance on the gifts and use of them. That is why most believers don’t consider affiliating with a particular denomination significant.
Besides, as pointed out earlier, since they are non-Catholic, they are considered heretical by default by the Catholic church so it’s pretty much irrelevant which one it is.
