Jehovah’s Witness was founded by Charles Taze Russell in the 1870s, whereas Mormon was founded in 1830 by Joseph Smith. The actual name for this denomination is The Church of Jesus Christ of Latter-day Saints. Although both denominations are usually classified as Orthodox Christians denominations, there are a lot of differences between the two, especially when you compare some of the things that constitute their beliefs.
Jehovah's Witness and Mormon don't have the same understanding of the concept of the Trinity. Mormons believe God, Jesus, and the Holy Spirit are separate beings, and, as such, they should be worshipped separately. Mormon preaches that Jesus Christ and all human beings are God's children. Like Mormons, Jehovah's Witnesses believe that God created all human beings, but Jesus Christ is the only son of God and that the Holy Spirit is not a person but the spirit of God. Mormons believe that the soul of every human will be resurrected and will be taken to heaven by Jesus Christ. In contrast, Jehovah's witnesses believe that; although all the sleeping souls would be resurrected by Jesus Christ, just 144 000 will be taken to heaven, while others will continue to live on earth.
Jehovah’s Witnesses and Mormon are both orthodox Christian denominations. The main ambition of these sectors is to go back to the ancient form of religion. Both faiths see the primitive church as the way to achieving salvation. While both follow similar principles and beliefs, there are a few key similarities between the two. Neither groups trust in the Christian belief in the Holy Trinity.
Mormons worship God, Jesus, and The Holy Spirit as separate entities. Mormons believe that all human beings are God’s children like Jesus Christ, whom they know as Jehovah in the Old Testament. Jehovah’s witnesses ascertain that the only God is Jehovah. His son is Jesus and that Jehovah created all human beings. Mormons believe that upon their death, they will be separated from their soul, then it comes back through Jesus Christ. He resurrects them and guides them to heaven. Jehovah’s Witnesses, on the other hand, believe that after death, the spirit is put to rest and that only a specific number of human beings will be resurrected to heaven.
