Frankly, in some areas, the Catholic church has indeed needed to be critiqued (after all, some Catholic leaders have critiqued other Catholic positions or trumped earlier Catholic doctrinal stances!).
A key difference: When a Mormon "prophet" or "apostle" speaks, it's regarded as the very "voice" of God as related to his supposed "seer and revelator" role! IoW, it's not mere leader opinion. The Mormons are bound to it -- to "honor" it as if was pseudo-"scripture."
That's a wide gap 'tween statements made by some Christian leaders in the centuries vs. Catholicism or Mormonism for that matter.
Some Christian leaders' comments thru the century may be quite discerning; others, just their opinion. But it's not on the level of Revelation chapter 23!!!
In sharp contrast, Mormonism expects its leaders' statements to be regarded as "revelations from God" offered up by their seer.
For example, anything said or done by 19th (or early 20th) century Southern Baptists wasn't said or done by either...
(a) a Southern Baptist "Pope"...
(b) a Southern Baptist head hauncho who was supposed to be God's very vocal chords on his behalf for the entire planet.
This, unfortunately wound up translating into SOME 19th century Southern Baptist leaders who gave wrongful/sinful opinions on race issues, for example -- some from the pulpit of a given church...and wrong/sinful decisions (breaking away from the Northern Baptists)
In sharp contrast, Lds "prophet" Brigham Young said he had never preached a sermon -- that upon review & correction of any notes taken down by their secretary -- that couldn't be called "scripture."
AND...this wasn't just Young's "opinion..." THIS very concept is recorded/undergirded in Lds' "sacred 'scriptures'" -- Doctrines & Covenant:
'Twas a November day 1831...when Joseph Smith said:
...this is an ensample unto ALL who were ordained unto this priesthood...and this is the ensample unto them,
that they shall speak as they are 'moved upon' by the Holy Ghost... [v. 4:] And WHATSOEVER they shall speak when moved upon by the Holy Ghost SHALL BE SCRIPTURE,
shall be the will of the Lord,
shall be the mind of the Lord,
shall be the word of the Lord,
shall be the voice of the Lord...

And it will, in all likelihood, that poster will be a MORMON who wants to get the thread jabbering between C's and P's so that the deceived MORMONs can slink away; relatively unscathed.
