Most members of the Mormon church are talking about the garment when they refer to Mormon underwear. The garment is underclothing received during the initiatory ordinance in the temple. It is more properly known as the "garment of the holy priesthood". It represents the garment given to Adam when he was found naked in the garden of Eden and is believed by Mormons to offer "spiritual" protection against evil forces. It is an thus an undergarment with religious and spiritual significance to the Mormons.
The garment was introduced as part of temple worship by Joseph Smith, Mormonisms founder during the Nauvoo period sometime around 1842-43, about seven weeks after he had been initiated into Freemasonry. Smith was heavily influenced by the Old Testament and often used OT conceptions of priesthood as the basis for the temple worship. Joseph Smith was also influenced by his modern surroundings in designing garments. Thus, as Joseph Smith was a Mason, he included some Masonic symbols as part of the temple garment. Four symbols known as the "Marks of the Holy Priesthood" is sewn into it. Over the left breast is "the mark of the compass"; over the right breast is "the mark of the square"; over the navel is a mark, and another appears over the right knee (the latter two are one-inch horizontal lines). These marks are supposed to remind the wearer of the covenants assumed in the temple ritual.
The garment is usually white and available in one-piece (ankle-length, long sleeve; ankle-length, short sleeve; button front; knee-length, short sleeve) and two-piece styles, some of which are available in square back, V-back, crew neck, maternity and nursing varieties. They may be made of cotton, polyester, nylon, nylon-mesh, rayon and/or rayon-nylon (Bemberg) fabrics. Early Garments were reportedly made of unbleached muslin and/or cotton.
Before receiving the endowment members of the Mormon sect are not authorized to wear the garment. Those who have been disfellowshipped or "excommunicated" are also asked to not wear the garment. When Mormons go through the Endowment ceremony in the Mormon temples and receive the garment, they are asked to wear it as a sign of being an endowed member of the Mormon church. These garments must be worn by Mormons for life and no other underwear can be worn. Mormon women must wear their bras over their garments and some Mormons even believe that one must wear the garments during marital relations so the child will be born "under the covenant".
Some Mormons believe that the "holy" garment will protect them from fire, bullets, knives and other assaults if the person wearing the garments have kept all of their "temple covenants". Thus, the garment is often referred to by some as "magic underwear". However, this belief is not part of official Mormon doctrine. Mormons rather believe that the garment offers "spiritual" protection through the wearers commitment to spiritual covenants and makes no promise of physical protection. Plenty of Mormons have been injured and killed while wearing their underwear, they say.
During the washing and anointing ceremony the Mormon is told the garment "represents the garment given to Adam when he was found naked in the garden of Eden." The person is told that the garment "will be a shield and a protection to you against the power of the destroyer until you have finished your work here on earth." In general, Mormons view the garment as a symbolic and spiritual shield against the powers of Satan. Some LDS believe that the garment provides them with "supernatural powers" of physical protection. Bill Marriott, prominent Mormon and owner of Marriott Hotels International stated in an interview with Mike Wallace of 60 Minutes that he believed his garments protected him from being burned during a boating accident.
When a pair of "holy garments" becomes worn out, the owner of the garment must take a pair of scissors and cut out the embroidered symbols on the breast, navel and knees. These symbols must then be burned by fire as they are treated as "holy relics". The worn out garment can then be disposed of by throwing the garment into the trash.
The garment also serves the purpose of being a standard for modesty. Because members are asked not to allow the garment to be displayed they must then cover the garment completely with clothing that covers from the shoulders to the knee. This standard for modesty is not just for those members who are endowed. Mormon leaders encourage all members of the sect to wear modest clothing from the time they are young. This also helps many members when making the transition from not wearing garments to wearing them, because their clothes are modest enough to cover the garment.
A Mormon church owned company called "Beehive Clothing" is the only company authorized to make garments. These stores are located throughout the world usually near Mormon temples. Members can also order garments through catalog. Beehive Clothing offers garments in ten different fabrics and customized garments such as a brown garment for those serving in the military, and garments for individuals with special needs.
Deceased Mormons will be buried in their temple garments. Dressing the corpse is done by the ward's Relief Society President if the mortician is not an endowed member, so as not to reveal anything.
And How The Ceremony Is Performed In The Temple
After showing his Temple Recommend to a worker stationed near the entrance inside the building, the patron repairs to the men's dressing area, where he is assigned a private locker (dividers and a door ensure privacy). After disrobing he covers himself with a "Shield"-a white poncho-like linen covering with a hole in the top for his head and open sides (held shut while walking). Covered in the Shield, he carries one pair of Temple Garments (one-piece style) to the Washing and Anointing area, and waits on a bench until directed by a temple worker to enter one of the Washing and Anointing booths through a veiled partition. The booths are simply small cubicles made up of suspended lined veils.
When called for, the initiate enters the booth and hands his Garments to a worker who places them on a towel rod. As the initiate stands upright in his Shield the temple worker wets his fingers under a small faucet of running water in the booth, and lightly touches each area of the initiate's body through the open sides of the Shield.
Brother _______, having authority, I place this Garment upon you [for and in behalf of ______, who is dead], which you must wear throughout your life. It represents the Garment given unto Adam when he was found naked in the Garden of Eden, and is called the Garment of the Holy Priesthood. Inasmuch as you do not defile it, but are true and faithful to your covenants, it will be a shield and a protection to you against the power of the destroyer until you have finished your work here on earth. With this Garment I give you an New Name, which you should always remember, and which you must keep sacred, and never reveal except at a certain place which will be shown you hereafter. The name is "______."
The New Name is then repeated by the patron, who has now completed the Initiatory Ordinances, and is ready to clothe for the Endowment. Upon giving the New name, the worker writes either a "1" or a "2" on the name slip. This indicates which of the "New Names" in use that day the patron received. The New Name may be almost any given name found in the Bible or the Book of Mormon. When the patron has not undergone Initiatory Ordinances, but is simply about to do an "Endowment for the Dead" he receives the New Name in a booth, dressed in his white shirt, tie, pants, socks and slippers. Holding a name slip, he obtained the New Name by the following rite:
Brother ______, having authority, I give you a New Name, for and in behalf of ____, (patron and the worker read name of deceased), who is dead, which you should always remember, and which you must keep sacred, and never reveal except at a certain place that will be shown you hereafter. The name is "_______".
It should be noted that all Mormon males and Mormon females are given a unique name that is chosen for each day of the year. Therefore, all Mormons males that enter the temple on a given day of the year will be given the same name, and the name chosen for females for that day, the females will receive.
When a married couple receive their names on the same day, the male will be told the name of the female, however, the name of the male is kept secret from the female and never to be revealed.
The whole reason why LDS wear these outfits is because they supposed to be garments of protection, thus LDS believe that by wearing them, they are afforded protection from the enemy (Lucifer/Devil). Christians also believe in protecting themselves from demonic attack and agree on the issue that spiritual warfare does in fact exist, and has a direct impact on us individually.
Christians too believe we need to be protected from the enemy. Our understanding is that God has provided us with the "Armor of God" that Paul mentions in Ephesians Chapter 6. But since the devil is a spirit, this battle is a spiritual battle and therefore exists in the spiritual domain of our existence.
Then how does one "put on" the armor of God? It's not like stepping one foot at a time into some strange pants and putting a shirt over your head. Christians put the Armor on by FAITH. Christianity is based on FAITH while Mormonism is based on unscriptural superstition.
From Ex-Mormon (anonymous posting):
"It is doubtful that most non-Mormons have any idea that Mormons wear "sacred" or secret underwear. There is nothing in their life that would equate to wearing regulation underwear and the fear, guilt, keeping up appearances, sneaking to take them off, not telling a spouse, associated with wearing them.
Just the idea that human beings are not acceptable unless dressed in regulation underwear must seem absolutely bizarre to outsiders.
How crazy is it to be afraid to take off your underwear, be seen not wearing it, and how a spouse has to power to destroy your personal temple clothing if you are not "worthy" in their eyes.
I maintain that the most powerful thing Mormonism does to control it's members by fear, guilt, and shame is the regulation underwear!
… Their power is so subtle that taking them off permanently is not only psychologically difficult, it is physically difficult as well. The combination of those two factors is what gives Mormonism egregious, unfathomable, total control over it's members. If you tell a Mormon they are controlled by their underwear, they will vehemently deny it."
In order for a Mormon to get into the Celestial Kingdom, a Mormon must take out their endowments. In order to take out their endowments, they must be temple worthy. In order to be temple worthy, they must pay 10% of their income to the Mormon church. In order to keep the temple covenants, they must wear the garments. A Mormon can only buy their underwear from the Mormon church.
In all reality, garments in the LDS Church are an absolute control mechanism. It is another key in the Cult of Mormonism to bind a member to the church. If you can create a religion and require your members to wear special underwear, you will have a high level of power over those members.
Many Mormon couples conceive their children while both wearing the garments. Some LDS women insist that the child be born while wearing garments so that the child would be born "under the covenant". Huge arguments between LDS patients and their doctors ensue when Mormons refuse to take their garments off for surgery.
Those who leave Mormonism find that tossing out the garments is the hardest part of leaving. It can take upwards of two years to finally overcome the fear of removing them. According to testimonies, and even an exorcist, the Mormon undergarments come with a curse (or spell). That's probably why the garments are associated with magic, and why some feel they are controlled (or possessed if you will) by their underwear.
From Ex-Mormon (anonymous posting):
"After removing the garments, I ended up on [a site]... and thought to myself that if even a quarter of the evidence presented was true, I would have to leave. I decided to disprove the evidence. I slept for a grand total of 4 hours during the next 72 hours. I stayed on only church-owned websites (i.e. lds.org to reference scriptural passages, BYU's library to find older texts). To my astonishment, I could not disprove any of the evidence, and actually ended up proving everything I looked up. I am thoroughly convinced that I would never have finished the exercise had I still been wearing the garments.
I have spent the last several months trying to devise a way to get my DW to knowingly, willingly remove her garments. I know that she is a bright, intelligent woman, but wearing the garments keeps her locked in the mormon mind... to a degree that she can't even see herself as trapped (just as I couldn't). I know that if I can get her to lose the garments, it would be a very short time until she scrutinizes (and leaves) mormonism."
Joseph Smith, the founder of Mormonism, received a "revelation" to reinstitute polygamy. This contradicts the teaching of Jesus Christ (Mt. 19:4-9). Thus, Mormons follow the false prophet Joseph Smith and deny the teaching of Christ. They need to heed Galatians 1:8-9. It teaches us to reject anyone who would preach a new gospel, which is exactly what Joseph Smith did. It should also be pointed out that Mormons believe that the Church of Christ was founded by Jesus and then defected shortly after, only to be reconstituted in the latter days. That contradicts the promises of Christ to His Church (Mt. 16:18-20; Mt. 28:20): that the Church is indefectible and that He would always be with it. In addition, Mormons deny the Trinity; believe that God has not always been the Supreme Being of the universe, but attained that status through righteous living and persistent effort; that He has not always existed but has had a father like everyone else; that Jesus is a god (but a god that is unequal to God the Father) and that any human can also become a god; they also believe Jesus and Satan are brothers.
Christians know this about God: there is only one true God (Deuteronomy 6:4; Isaiah 43:10; 44:6-8), He always has existed and always will exist (Deuteronomy 33:27; Psalm 90:2; 1 Timothy 1:17), and He was not created but is the Creator (Genesis 1, Psalm 24:1; Isaiah 37:16). He is perfect, and no one else is equal to Him (Psalm 86:8; Isaiah 40:25). God the Father is not a man, nor was He ever (Numbers 23:19; 1 Samuel 15:29; Hosea 11:9). He is Spirit (John 4:24), and Spirit is not made of flesh and bone (Luke 24:39).
Mormons are totally antichrist and of the devil! There are other things that could be mentioned about wacky Mormon beliefs, but they can be found without too much trouble by those who want more information.
