What is LDS
The LDS Church, also known as The Church of Jesus Christ of Latter-day Saints or Mormon Church, is a Christian religious group that believes it has restored the original church that Jesus Christ created. It was started in 1830 by Joseph Smith in New York. It is now based in Salt Lake City, Utah. Today, the church has over 17.5 million members around the world and more than 100,000 volunteer missionaries.
The LDS Church believes that after Jesus and His apostles died, the original church lost its way. They believe God chose Joseph Smith to bring back the truth through modern revelations. In addition to the Bible (King James Version), they follow other books like the Book of Mormon, Doctrine and Covenants, and the Pearl of Great Price.

Mormons believe that every person lived with God as a spirit before being born. They also believe that God has a physical body like a human, and Jesus is His first-born spirit child. Mormons believe in Jesus as their Savior, but they do not believe He is equal to God the Father in the same way many Christians do.
For Mormons, being saved means having faith, repenting, being baptized, and living a good life by following God’s commandments. They also believe in the importance of temple ceremonies, eternal marriage, and doing family history so they can baptize their ancestors by proxy.
After death, Mormons believe people go to different “kingdoms” depending on how they lived: the Telestial Kingdom (for the wicked), the Terrestrial Kingdom (for decent but not faithful people), and the Celestial Kingdom (for the righteous, where they can live with God and even become gods themselves).
What is FLDS
The FLDS Church, or the Fundamentalist Church of Jesus Christ of Latter-Day Saints, is a breakaway religious group that split from the main LDS Church. Although it shares some roots with Mormonism, it is not part of The Church of Jesus Christ of Latter-day Saints and is not recognized by it.
The FLDS group still continues the practice of polygamy (one man having multiple wives) which the LDS Church officially banned in 1890. FLDS members believe that polygamy is a key part of reaching the highest level of heaven.

The FLDS is much smaller than the mainstream LDS Church. It is mostly based in isolated communities in Utah, Arizona, and a few other areas. This group is known for its strict control over members’ lives, including dress, education, marriage, and communication with outsiders.
The FLDS Church has been led by several controversial leaders. The most controversial was Warren Jeffs. He claimed to be a prophet who spoke directly for God. Jeffs was later convicted of serious crimes like child abuse and arranging underage marriages. As a result, the group has been described by many as a cult. It has also been involved in multiple legal investigations.
