I'm not a Mormon, so perhaps you can point me to the teachings that state that a 'prophet' can reassign a man's 'wives' and children to someone else if the man ticks the prophet off.
I am and there is no such teaching. Typical anti-mormonisim.
George D. Smith wrote:
"Beginning in 1841, Joseph Smith took as plural wives several married women, as if exercising a variant of the feudal droit du seigneur: a king's right to the brides in his domain. This option was presented to the married woman as a favor to her. A woman who wanted higher status in the celestial kingdom could choose to leave a husband with lower status in the church, even if she had been sealed to him, and become sealed to a man higher in authority.
On February 19, 1854, Jedediah M. Grant, second counselor to President Brigham Young delivered a sermon that made it very plain that Joseph Smith did ask for other men's wives:
"What would a man of God say, who felt aright, when Joseph asked him for his money? He would say, 'Yes, and I wish I had more to help to build up the kingdom of God.' Or if he came and said, 'I want your wife?' 'O yes,' he would say, 'here she is, there are plenty more.'... Did the Prophet Joseph want every man's wife he asked for? He did not... If such a man of God should come to me and say, 'I want your gold and silver, or your wives,' I should say, 'Here they are, I wish I had more to give you, take all I have got.' " (Journal of Discourses, Vol. 2, page 14)
On October 8, 1854, Brigham Young made these controversial comments: "Then I reckon that the children of Adam and Eve married each other; this is speaking to the point. I believe in sisters marrying brothers, and brothers having their sisters for wives.... "This is something pertaining to our marriage relation. The whole world will think what an awful thing it is. What an awful thing it would be if the Mormons should just say we believe in marrying brothers and sisters. Well we shall be under the necessity of doing it, because we cannot find anybody else to marry." (The Teachings of President Brigham Young, Compiled and Edited by Fred C. Collier, Vol. 3, pages 362, 368)
I can go on and on and on with words right from their own mouths as quoted in books written, edited and published by the church itself. They are damned by their own words.
