Hi Roger...
I'm thinking this whole, "Prophets just speak their opinion" excuse is fairly new... is it?
BH Roberts made this argument many many years ago. I do not think it is really new.
I could be wrong, and it might be that I just was unfamiliar with apologetics but until recently, I had never, EVER heard such a thing.
Course Roberts was probably one of the earliest LDS apologists and was one of the first to deal with some of the teachings from the 19th century leaders we wished were never said.
I was taught that prophets are in communion with Christ who is leading the church; that prophets are inspired, receive revelation, and are the mouthpiece for Jesus.
Even Joseph Smith said that not everything he said was as a prophet.
.However, I'm wondering if this new mantra will find its way into mainstream chapel Mormonism? I don't know
I think it more used by apologists than by mainstream members. Based on the comments I heard in HPQ today there is a lot of devotion to especially what the living prophet says.
I think the evolving "doctrine" concerning those with African ancestry (which is really all of us.. sigh), and dark skin, is going to be similar to the LDS stance on the SSA community. Just give it a few years (decades?), and this whole "Satan is behind homosexuality, which is just a horrible choice by misled people" idea will be eliminated as just the silly opinion of these leaders who just didn't understand, (or further light and knowledge... smile).
by the way, I also have a copy of Mormonism and the Negro... WOW! :-(
It is an eye opener but keep in mind the author was never a church leader.
