“Fortunately for me, all the rest of Christendom, outside of the Roman Catholic Church agrees with me as to what the Roman Catholic Church is and is not.”
Really? Show me the evidence that the Orthodox all share your understanding that the Catholic Church is merely a human institution. You’ll fail - because they don’t agree with you by a long shot.
“That is not a comment on persons who may be members of the Roman Catholic Church, but the human institution that that Church is.”
It is merely a comment about one person’s lack of knowledge and understanding of basic fundamentals of Christianity. One person’s - and that one person is YOU.
“basic fundamentals of Christianity”
So much of what you call “basic fundamentals of “Christianity” is no more than “basic fundamentals” of Catholicism, period.
