*crickets*
Didn't think I'd get an answer to that one. But I think I have it, nevertheless.
Pre-Vatican II the Catholic Church made it very clear that Catholicism is the only true religion and the only true Church. So, yes, anything that is not Catholic is false. This was (and is) the Traditional Catholic position.
And what’s with the *crickets* comment? You posted late at night. I went to bed.
“Is it your position that non-Catholic Christians are practicing false religion?”
...the thread is days old, I realize, but in case you’re lurking about, I’ll take a stab at that, speaking as what I call a ‘traditionalist’ Catholic...
...it is not my opinion that you and others are practicing ‘false’ religion...you invoke Christ; such invocation requires a more substantive response than a blithe charge of apostasy...but my notion of worship requires a bit of introspection as well, as I seek the most perfect expression of it, in order to satisfy an innate desire for meaning sought out of human endeavor...my gut tells me the closest expression of perfection we’ve attained is the Catholic Mass as it existed prior to the innovations in 1965, and beyond...
...however, it falls to better brains than mine to determine who is practicing falsity and who is not...though that doesn’t stop me from offering opinions...and my noggin says that falling short of perfection, or even the closest thing to perfection, is a far cry from falsity...and since I am not in possession of the secrets of existence and being, I cannot in truth castigate anybody as practicing false religion, even if the rites of that worship call for standing on your head and baying at the moon...in other words, I acknowledge, I may be wrong about the nature of religion, and my idea of perfection as rotten as a month old tomato...
...all told, then, my belief being that the preconciliar Catholic Mass represents the truest virtues of Christianity, requires me to hold that any worship other than that is that much more imperfect, which certainly includes the rite that Catholics today claim to be ‘the Mass’, and naturally, any Protestant service, and thus ‘bending away’ from Christ and His highest ideal...but false? No. As stated, not achieving perfection is not practicing falsity, and true belief in the Triune Godhead cannot, in my studied opinion, put one’s salvation in jeopardy...
...I know I’ll not please everyone with this answer, but who seeks that...and my prior comment about your eyesight stands, as only a blind man could miss the viciousness of some Protestants on this forum toward the RCC...
