Oh, so the godhood thing was the "important part"?... "Then shall they be gods, because they have no end; therefore shall they be from aeverlasting• to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be bgods•, because they have call• power, and the angels are subject unto them."
And what if a wife didn't like that "unimportant" polygamy part?...
"And again, verily, verily, I say unto you, if any man have a wife, who holds the keys of this power, and he teaches unto her the law of my priesthood, as pertaining to these things, then shall she believe and administer unto him, or she shall be destroyed, saith the Lord your God; for I will destroy her; for I will magnify my name upon all those who receive and abide in my law."
So God is going to destroy a woman who didn't believe in the "unimportant" plural wives thing?
After 1852, when the Mormon Church was openly practicing polygamy, the leaders of the church were declaring that it was absolutely essential for exaltation. Joseph F. Smith, who served as the 6th president of the church, made this emphatic declaration concerning the importance of polygamy:
"Some people have supposed that the doctrine of plural marriage was a sort of superfluity, or non-essential to the salvation of mankind. In other words, some of the Saints have said, and believe that a man with one wife, sealed to him by the authority of the Priesthood for time and eternity, will receive an exaltation as great and glorious, if he is faithful, as he possibly could with more than one. I want here to enter my protest against this idea, for I know it is false... Therefore, whoever has imagined that he could obtain the fullness of the blessings pertaining to this celestial law, by complying with only a portion of its conditions, has deceived himself. He cannot do it. When that principle was revealed to the Prophet Joseph Smith,... he did not falter, although it was not until an angel of God, with a drawn sword, stood before him and commanded that he should enter into the practice of that principle, or he should be utterly destroyed, or rejected....
"If then, this principle was of such great importance that the Prophet himself was threatened with destruction,... it is useless to tell me that there is no blessing attached to obedience to the law, or that a man with only one wife can obtain as great a reward, glory or kingdom as he can with more than one,...
"I understand the law of celestial marriage to mean that every man in this Church, who has the ability to obey and practice it in righteousness and will not, shall be damned, I say I understand it to mean this and nothing less, and I testify in the name of Jesus that it does mean that." (Journal of Discourses, vol. 20, p. 28-31)
In 1891 the First Presidency and Apostles of the Mormon Church made the following statement in a petition to the President of the United States: "We formerly taught to our people that polygamy or celestial marriage as commanded by God through Joseph Smith was right; that it was a necessity to man's highest exaltation in the life to come." (Reed Smoot Case, vol. 1, page 18)
Brigham Young made this uncompromising statement on August 19, 1866:
"The only men who become Gods, even the Sons of God, are those who enter into polygamy." (Journal of Discourses, vol. 11, page 269)
Do you need any more info on this "unimportant" part?
You are wasting your time. As best I can tell, all eternal proclamations can be overturned by prophecy.
The practice of plural marriage wasn't the important part of the "new and everlasting covenant"; the doctrine of eternal marriage was. Your original accusation was that the Church had abandoned a "new and everlasting covenant" by discontinuing plural marriage. I was explaining to you that the practice of plural marriage was not the "new and everlasting" part.
That's not to say that plural marriage wasn't a commandment; it was. All the other stuff you quote confirms that the practice of plural marriage was given by command, and that it was not to be ignored.
Go read the story of Israel and God's commandment to them to completely destroy the Canaanites. Men, women, children and beasts. He commanded them to kill every living thing.
Now, killing women and children is a particularly nasty thing. No God-fearing person would normally ever want to consider it. But there it is. Commanded by God. They fulfilled that commandment, then discontinued the practice by not wiping out whole peoples afterward.
The real question of plural marriage is whether or not it was a command given by God. If it was, then it must be obeyed, just as His command for the Israelites to kill was to be obeyed. Our position is that it was commanded by God, through a living prophet, just as the command to Israel to slay the Canaanites was given by God through a living prophet.
