Can you be more vague?
No. I like specificity.
BC it is difficult at time sto converse with you regarding doctrine because your definitions of what constitutes doctrine are self fulfilling.
Well no, my definition of doctrine is the same is the LDS Church's definition. But feel free to query more about it and I can show you doctrine based on the Church's definition.
30 years from now do you think the Church will have changed it's stance on homosexual marriage outside the church?
If there are any changes, I believe the net effect on doctrine will be zero as per the other issues I mentioned.
Do you believe the church has remained unscathed to date regarding the homosexual issue?
It's being brutally assaulted along with the rest of society regarding the homosexual issue. So no, not unscathed. The Church certainly has put a different face on it, but no doctrine has been changed. Homosexuality remains a sin and of course the Church does not perform homosexual marriages.
But what I'm exploring is if the principle I highlighted in blue is actually a truism about the LDS Church.
The church leadership HAS repudiated the "curse of Cain doctrine." Now they say over and over, "we don't know the reason."
Not knowing the reason does not repudiate the doctrine. For example, Abraham 1 has not been removed from canon.
The church is more sensitive to public pressure now than it has ever been.
Sure. But does the Church change the doctrine or present a different face? I see no evidence of the former.
