Pardon me for interrupting you, but the word, communism, had a good definition long before it was co-opted by modern demagogues. Please refer to the “Early Communism” portion of this Wikipedia article for some insight into this.
en.wikipedia.org/wiki/Communism
True use of the word is Christian, or at least religious. That is why it was adopted by the early Church as a method to deal with the support of all believers, regardless of their status. And, yes, true communism does apply to monastic and convent life, because what is owned, is owned “in common”, and what is produced, is produced for the benefit of all.
Please don’t negate the proper use of the word, by confusing it with a social experiment which had every right to fail…for many reasons, including the attempted supression of belief in G-d.
True communism, as noted before, here in this thread, is optional. That is one reason why the word itself needs to be used properly, to illustrate the improper coercion demanded by dialectic communism.
The word, “religious” is a poor substitute for true “communism”, due to its vague application to monastic living. That we do not police our use of English more carefully is due, oftentimes, to a misunderstanding of the history of the word’s use.
So, the OP’s question used the word capitialized; that is a proper use of the word used to describe Marxism, or atheistic Communism, or materialistic Communism, all perversions of the original idea and meaning of the word.
Peace.
