Which ceremonies take place inside Latter-day Saint temples?

In the Church of Jesus Christ of Latter-day Saints, temples are sacred spaces reserved for specific religious ceremonies, known as ordinances, which are distinct from the weekly services held in local meetinghouses.12

The essential ceremonies performed in temples include:

• Baptism for the dead: A rite performed by proxy for individuals who died without knowledge of the faith.13
• Endowment: A rite of adult initiation where participants are ritually washed, anointed with oil, and taught about the church’s tenets for salvation. During this ceremony, initiates make sacred covenants with God and receive knowledge and blessings.12
• Sealing: A ceremony that unites husbands, wives, and children, which can also be performed by proxy for the deceased.1

To participate in these temple ceremonies, members must first undergo a "temple recommend" interview with church authorities to confirm their readiness and worthiness. Once an individual has received their endowment, they are privileged to wear temple garments as a reminder of their covenants.42
