What exactly does it mean to be a "non-practicing observer" at a non-Catholic service of worship?

[Peter_J]

If non Catholics had Holy Communion I would partake…but it is a sacrament they do not have, regardless of the ersatz ceremony. Not much else is out of whack at a service…most of them. They enjoy reading the Bible, as we do but they read the verses through the spectacles of their own theology.

The Orthodox, Assyrians, PNCC, and a few others do have valid Sacraments, including the Eucharist.

I understand that but I thought we were on the subject of protestants even though the word was not used.I attend a non Catholic denom with my wife on occassion but I do not take their version of communion.

So to clarify, when you said "If non Catholics had Holy Communion … " you mean “Catholics” including Orthodox, ACoE, and PNCC?
