Most of my relatives who left the church, lost their faith over the doctrine and practice of polygamy. It was the catalyst that led them to discover the other issues, like the Book of Abraham.
Wade, you said on MAD:
My contention is that anti-Mormon material is irrelevant to an accurate understanding of: 1) the end that God desires for his children; 2) the gospel he has instituted for achieving that objective; 3) the role God has designed for prophets in relation to the gospel, and 4) the faith equation revealed by God. In short, for an LDS to have their faith negatively influenced by anti-Mormon material would necessitate their having not correctly understood the gospel to begin with.
How are you defining anti Mormon material?
Reading the unvarnished "anti Mormon?" history on the doctrine of polygamy taught by the Prophets who lived it was the testimony breaker for me. Learning that plural marriage is required for exaltation is absolutely essential to:
“the end God desires for his children,”
“the gospel he has instituted for achieving that objective,”
“the role God has designed for prophets in relation to it,”
and “the faith equation revealed by God” in gaining a testimony of that principle.
Either the decades of sermons on this requirement to enter plural marriage for the highest level of the CK are correct, or the claims of the church that it is led by Prophets are false. In a religion where eternal marriage and the progression to become Gods and create life to populate planets is essential to the Mormon plan (and the crowning glory) , polygamy is paramount to Mormon afterlife and Godhood. If the Prophets got it wrong on this doctrine, the religion falls apart.
You also said in your Lexus car analogy:
The private marital affairs of the founder of Lexus has no relevance to whether the Lexus meets the stated objectives of my friend and/or the stated intent of the Lexus automobile.
So is it your belief that Joseph Smith had nothing but adulterous affairs that had nothing to do with the Mormon religion/car?
I agree that a Prophet's sexual sins do not make a religion true or false, but if the founding Prophet of a religion commands in God's name to have sexual intercourse with him as essential to their exaltation, as the restoration of the Patriarchal order in heaven, then it is relevant.
