Some criticize the LDS for not dispaying crosses and the LDS people for not wearing crosses. The LDS do not ignore the cross, we don't think it is foolishness, we dont criticize others for displaying it, we have artwork in our meeting houses depicting Christ on the cross. However, we choose to focus on and remember both the blood and body of Christ and Christ's triumph over death. Our symbol is the empty tomb.
We try not to display outward clothing claiming our sprituality. Just because a person wears a cross doesnt mean they are Christian. And wearing a cross has nothing whatever to do with salvation or sanctification. Christ criticized the Jews for their large phylactories and enlarging the blue hem of their robes.
Matt. 23:5 But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments,
Matt. 6:3 But when thou doest alms, let not thy left hand know what thy right hand doeth:
LDS wear the undergarment of the preisthood to remind us of the atoneing sacrifice of Jesus Christ. Each morning we "put on" Christ's atonement which was done in the garden and on the cross, which covers our nakedness before God, and reminds us that we have been washed white and clean with the blood of Jesus Christ. And no one knows who is wearing the undergarment except those who are wearing it.
LDS men and women have been set appart and sealed in their foreheads before the great tribulation (Rev. 7:3, Rev 9:4) and second coming of the Lord as priests unto God in modern Christian temples in the last days (Isa 2). The Bible prophecies that Israel will be sanctified by receiving the everlasting covenant of God in a restored Christian temple and not a restored Jewish temple (Ezekiel 37:26-28).
While Satan is busy marking his followers with the mark of the Beast. Those who have accepted Christ and have overcome are sealed by God in holy temples. These are they who will be empowerd by the Holy Ghost as promised by John in revelations and set apart as was Aaron (Heb. 5:4), ordained a priest, washed and annointed. These are they who will be given white undergarments (Lev 16:4) and robes symbolizing that they have been washed in the blood of Christ (Rev3). These are they who will be given a new name and take upon themselves the name of Christ (Rev 3). These are they who will be made kings and priests unto God (Rev 3). And these are they who will be prepared to be received by Christ at his second coming who will come as the King of kings and Lord of lords.
And those who are made high priests to Jesus Christ to minister his sacrifice and not their own. In the last days, priests will not just be ordained from the tribe of Levi and from the country of Israel, but they are the 144,000 (large number), from every tribe and from every nation. This is the what is ment by the priesthood of all believers. All believers are actually seal, ordained and set apart to the priesthood.
1 Pet. 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
Gal. 3:27 For as many of you as have been baptized into Christ have put on Christ.
Gen. 3:21 Unto Adam also and to his wife did the Lord God make coats of skins, and clothed them.
Heb. 5:4 And no man taketh this honour unto himself, but he that is called of God, as was Aaron.
Leviticus 16:4 He is to put on the sacred linen tunic, with linen undergarments next to his body; he is to tie the linen sash around him and put on the linen turban. These are sacred garments; so he must bathe himself with water before he puts them on.
