Mormonism never was related to Christianity...
Joey Smith hated the LORD Jesus Christ and Christians...
He wanted to get as far away from Christianity as he could...
He opposed the tenets of Christian beliefs as set in the Word of God, the Bible.....
He corrupted all 10 of the Commandments ...for instance replacing Thou shalt not commit adultery with the necessity for polygamy to become a god and go to the Mormon idea of an afterlife..
and in place of the LORD Jesus Christ Joey Smith himself became the judge...
It became more of a deadly sin to disagree with Joey Smith and Brigham Young than to disobey God...
Even the form of redemption is unrecognizable...
Salvation for the living through the shed blood of the LORD Jesus on the Cross being replaced with proxy baptism of the dead..
Mormonism is a false religion closer to Islam than anything Christians believe...
I’ll respond to everyone at once. Please note I do not believe Joseph Smith Jr or the BoM to be Christian.
“Mormonism never was related to Christianity...”
Originally, it was a revival of certain ancient Christian heresies, before Joseph Smith and Brigham Young became full-blown apostates.
“Joey Smith hated the LORD Jesus Christ and Christians...”
That does not mean all his spiritual descendants today do. Keep in mind there are over 100 different Mormon sects. Not all are like the LDS. Some are making their way, slowly, back to Christianity.
“He wanted to get as far away from Christianity as he could...”
Agreed. But God has touched the hearts of some of his followers.
“He corrupted all 10 of the Commandments ...for instance replacing Thou shalt not commit adultery with the necessity for polygamy to become a god and go to the Mormon idea of an afterlife.”
Agreed. But keep in mind certain groups of followers rejected polygamy and polytheism, and came to believe either than Brigham Young was responsible, or that Joseph Smith was a fallen prophet and God struck him dead. So they believe the BoM without believing in polygamy or polytheism.
“Mormonism is a false religion closer to Islam than anything Christians believe...”
No disagreement here when it comes to LDS and Brighamite Mormonism, or Mormonism as Joseph Smith Jr practiced it near the end of his life.
“’. . .there are some branches of Mormonism that have remained or returned to Christianity.’
Then they are not Mormons. Why would they call themselves Mormons?”
Most of them have distanced themselves from the term “Mormon”, which they consider an insult. But still, they accept the BoM as being inspired scripture, while rejecting polygamy, polytheism, blood atonement, secret temple ceremonies, baptism for the dead, and MOST other LDS/ Utah Mormon practices that are unscriptural. So I think it is fair to say that they are Mormons making their was back to Christianity.
