I guess the most perfect church is admitting it’s not so perfect; so it must be a false religion.
“Perfect”, in Judeo-Christianity, is usually a term used to describe the Divine - not the human/earthly.
Thus, that a church (an earthly construct) is not perfect does not make it false.
It's more like some of the grassroots are saying that the prophecies of the "prophets" are turning out false en masse...
...all while the "old line" [Ya gotta understand the bulk of Lds general authorities are in their 60s, 70s, & 80s] "dig in" via denial.
It's one thing if somebody 'fesses up to being "wrong" in a sermon...
It's quite another when...
(1)...the propaganda line is "the Mormon god will NEVER let the Lds 'prophet' be led astray" [all as they believe that the church of Jesus Christ led by Jesus the Prophet supposedly -- per Lds doctrine -- went 100% AWOL for about 1800 years]...
...Which means the "old guard" HAS to "hold the line" and will not repudiate anything ANY specific general authority has ever said!
...and (2) The things Lds leaders have falsely said in the past weren't done in the vein of "speculation" -- but were REAL teachings REALLY proclaimed and REALLY embraced by REAL embodied beings!
After all...how many times does a thief have to be arrested for to go to jail for theft?
How many murders must a murderer commit to be convicted?
And how many false prophecies does a "prophet" have to give before being deemed a "false prophet." [Deuteronomy 18 lays this all out]
Alas. The Lds general authorities know this "false prophet" scorecard...
...And therefore can't even 'fess up one false prophesy...
Lest the entire rickety structure come crashing down like the Tower of Babel juggernauts of old!
