though I can’t speak for “Chistains” being a cult, Methodism started in England with John & Charles Wesley, as a reform movement. If you meant to type “christian”, then that is a general term for those that believe in Christ, of which Methodists are a subset, as is the Church of England, they all follow basic teachings that put them within Christianity.
Unfortunately for them, mormons do not fit into Christianity, they postulate several positions that are beyond the pale of any historic understanding of Christianity, be it ancient or recent.
They claim:
1) they are a restoration of the first primitive church
2) that Native American Indian Peoples are the remnant of Jewish retrogrades
3) that Joseph Smith was a prophet
4) that the Book of Mormon is scripture
5) that doing works get you into heaven
6) that god was once a man that progressed into godhood
7) that Lucifer is Jesus’ brother
8) that the garden of Eden had been near Far West, Missouri, USA
9) that Masonic rituals were really
10) that the mormon church is the only true church
short refutations of LDS claims
1) there are no examples of any early church following mormon doctrine, or LDS temple-like buildings
2) DNA, linguistics & archeology prove that the native peoples of the Western Hemisphere originated in Siberia
3) Mr. Smith made at least 64 prophecies, 58 that did not “come to pass”, just 1 wrong makes you a false prophet
4) No part of the BoM can pass the test of real history, no BoM sites have ever been found, no peoples, no “Reformed Egyptian” language. even the LDS church doesn’t follow any of the ideas in the BoM except saying that it proves Mr. Smith was a prophet, if that were true, why does the BoM contradict LDS teaching?
5) Jesus, the early church & the Reformation clearly teaches that “Salvation is by Faith” alone, Luther found this & so reformed the church closer to the primitive
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God:
Eph 2:9 Not of works, lest any man should boast.
Eph 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
6) the Bible clearly teaches that God is spirit, only Jesus took on the flesh, to die for us
7) Lucifer is a fallen angel, Jesus is God
8) The location of Eden is unknown, but the Bible mentions the Euphrates, see Gen 2:8-15
9) Mr. Smith became a Mason, then stole their rituals & incorporated them into Mormonism’s temple rituals
10) By the foregoing it proves to be a false church, a cult with its own very unchristian beliefs
Lucifer’s Angel would be a demon, not a pretty sight
