Honestly - I speak for myself in this post: RCs are not hated. RCC dogma, doctrine, etc. that rails against Scripture is. Same with Mormons - it ain’t them that are hated; it’s their doctrines of demons that deny Christ. Anyone who defends unbiblical doctrines is sure to feel the hatred that is aimed at the false teaching. Unless ad hominem attacks take place, one shouldn’t take attacks on doctrine personally.
Since the followers of Christ are hated because of their beliefs, which are identified with Christ, your point creates a distinction without a difference. It's a shame that, in addition to the pagans and worldlings who have always opposed the Catholic Church and its members, other brands of Christians direct so much similar animosity toward it.
A multitude of anti-Catholic threads here on FR bear this out. They often do not merely disagree with doctrine, they are smear threads, designed solely to make the Church look bad or ridiculous. Their posting is certainly engendered by hatred of some type! Likewise, there are threads with simple disagreement with Catholic teaching as a theme, which wind up getting hijacked by sometimes hundreds of posts that have not much, if anything, to do with the thread theme, but simply use it as a springboard to bring up vile imaginings or half-truths. Surely, those are not motivated in Christian charity!
Ignoring your assertion that Catholic doctrine is inspired by the devil as simply coming from ignorance, it is still true that much of what is directed against the Church is just raw hatred swinging wildly against what people see as Catholic shibboleths, or against what they think is "Catholic doctrine," but, in fact, is a total falsehood or strawman set-up to complain about. That we allegedly "worship Mary" is a good and common example of this sort of thing. No matter how many times it is denied, no matter how many times the Catholic catechism is cited to show this is demonstrably false, some people can't let go of it, for the thought that Catholics are idolators gives them, apparently, too much comfort. Archbishop Fulton Sheen got it right when he said: "There aren't one hundred people in the whole country who hate what the Catholic Church teaches, but there are millions who hate what they think the Catholic Church teaches." Events on this forum alone prove him right, in spades!
Well spoken, it’s the doctrine, not the person. Ignore the whiners.
Amen to that!
