In the Latter Day Saint movement (also known as Mormonism), a temple is a builing dedicated to be a house of God and is reserved for special forms of worship. A temple differs from a church meetinghouse, which is used for weekly worship services. Temples have been a significant part of the Latter Day Saint movement since its inception. Today, temples are operated by several Latter Day Saint denominations. The Church of Jesus Christ of Latter-day Saints operates over 120 temples worldwide to perform Endowment ceremonies, marriages, and other rituals for both the living and by proxy in behalf of dead ancestors. The Community of Christ operates two temples in the United States, which are open to the public and are used for worship services, performances, and historical education. Some Latter Day Saint groups, like the Church of Jesus Christ (Bickertonite), do not use temples and only worship in church branches or missions.
