why do Mormons wear garments some Mormons wear undergarments because they have chosen to make promises or covenants with God in temples these garments are worn as a reminder of their promises or commitments to God they are also a reminder of Jesus Christ and his atonement when was the Mormon garment introduced in May of 1842 Joseph Smith introduced a temple ceremony called the endowment in the upper room of his navoo store Smith invited his scribe some members of the cor of the 12 apostles and the first presidency to his store and introduced these men to the temple ceremony although the records do not explicitly talk about the temple garment other sources agree that this was the first occasion that temple garments were introduced do Mormons consider the Garment to have magical properties members of the Mormon Church would not characterize the temple garment as mystical or magical there are however some members who have cited experiences where they believe their garments offered them physical protection presumably this is where stories of garments having magical or mystical properties have come from for example Bill Marriott a hotel chain owner and member of the church told a story on CBS about his belief that his garments protected him from being burned in a fire in the temple ceremony one of the promises of wearing the Garment is protection however this protection is of a spiritual nature the general hand book for the church says that garments are worn as a reminder of covenants made in the temple and when worn properly throughout life will serve as a protection against Temptation and evil Mormons make promises with God in temples as part of these promises they commit to wear underclothing called the temple garment or garments in remembrance of the significance of Jesus Christ in their lives like many other religious people this special clothing reminds Mormons of commitments they have made with God and is an outward expression of an inner belief please like And subscribe and for an objective look at more topics on Mormonism visit Mormonism explained. thanks for watching
