You have had a Garment placed upon you, which you were informed represents the garment given to Adam and Eve when they were found naked in the Garden of Eden, and which is called the Garment of the Holy Priesthood. This you were instructed to wear throughout your life. You were informed that it will be a shield and a protection to you inasmuch as you do not defile it and if you are true and faithful to your covenants.
These garments are said to be a shield, and a protection to you against the power of the destroyer until you have finished your work here on earth. By wearing these garments at all times, it is taught that the individual Mormon, depending on his or her faithfulness, is protected both physically and spiritually.
The church administrative manual called Handbook 2 explains:
When properly worn, it provides protection against temptation and evil. Wearing the garment is also an outward expression of an inward commitment to follow the Savior. Endowed members should wear the temple garment both day and night. They should not remove it, either entirely or partially, to work in the yard or for other activities that can reasonably be done with the garment worn properly beneath the clothing. Nor should they remove it to lounge around the home in swimwear or immodest clothing. When they must remove the garment, such as for swimming, they should put it back on as soon as possible. Members should not adjust the garment or wear it contrary to instructions in order to accommodate different styles of clothing nor should they alter the garment from its authorized design. When two-piece garments are used, both pieces should always be worn. The garment is sacred and should be treated with respect at all times. Garments should be kept off the floor. They should also be kept clean and mended. After garments are washed, they should not be hung in public areas to dry. Nor should they be displayed or exposed to the view of people who do not understand its significance. (Handbook 2: Administering the Church 2010, 191.)
While this handbook says that a person wearing the garments is protected from temptation and evil, President Spencer W. Kimball said that he was
convinced that there could be and undoubtedly have been many cases where there has been, through faith, an actual physical protection, so we must not minimize that possibility. (The Teachings of Spencer W. Kimball, 539.)
While we are not insinuating that Mormons believe the garments will protect the wearer in all circumstances, certainly Kimball thought that there are many cases where there has been an actual physical protection. For instance, Bill Marriott of the Marriott hotel chain told CBS 60 Minutes interviewer Mike Wallace in 1996 that his garment had protected him in a boat fire. Despite the testimonies of Mormons who believe their garment has protected them from physical harm, it should be pointed out that there are seemingly faithful Mormons who wear their garment on a regular basis yet are killed or injured. For instance, President Spencer W. Kimball said on 31 May 1948:
Temple garments afford protection. I am sure one could go to extreme in worshiping the cloth of which the garment is made, but one could also go to the other extreme. Though generally I think our protection is a mental, spiritual, moral one, yet I am convinced that there could be and undoubtedly have been many cases where there has been, through faith, an actual physical protection, so we must not minimize that possibility. (The Teachings of Spencer W. Kimball, p. 539).
Wearing the garments is an indication of a persons righteousness. Seventy Carlos E. Asay thinks of the garment as the Lords way of letting us take part of the temple with us when we leave. He wrote:
A few years ago, in a seminar for new temple presidents and matrons, Elder James E. Faust, then of the Quorum of the Twelve Apostles, told about his being called to serve as a General Authority. He was asked only one question by President Harold B. Lee: Do you wear the garments properly? to which he answered in the affirmative. He then asked if President Lee wasnt going to ask him about his worthiness. President Lee replied that he didnt need to, for he had learned from experience that how one wears the garment is the expression of how the individual feels about the Church and everything that relates to it. It is a measure of ones worthiness and devotion to the gospel. (Ensign, August 1997, 19)
After quoting from Ephesians 6, Asay said the garment symbolized a part of the armor of God:
There is, however, another piece of armor worthy of our consideration. It is the special underclothing known as the temple garment, or garment of the holy priesthood. . . . This garment, worn day and night, serves three important purposes: it is a reminder of the sacred covenants made with the Lord in His holy house, a protective covering for the body, and a symbol of the modesty of dress and living that should characterize the lives of all the humble followers of Christ. . . . The piece of armor called the temple garment not only provides the comfort and warmth of a cloth covering, it also strengthens the wearer to resist temptation, fend off evil influences, and stand firmly for the right. (Ibid.,20-21)
