White Clothing on LDS.org
White Clothing: You’ve also noticed that everyone in the temple wears white, which is another symbol. White clothing symbolizes purity, worthiness, and cleanliness and that we are all equal before Heavenly Father.
Within the temple, all are dressed in spotless white to remind us that God is to have a pure people.18 Nationality, language, or position in the Church are of secondary significance. In that democracy of dress, all sit side by side and are considered equal in the eyes of our Maker.19
White Clothing in the Scriptures:

- Revelations 3:5
17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked:
18 I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see.
- Revelations 3:18
And it came to pass that Jesus blessed them as they did pray unto him; and his countenance did smile upon them, and the light of his countenance did shine upon them, and behold they were as white as the countenance and also the garments of Jesus; and behold the whiteness thereof did exceed all the whiteness, yea, even there could be nothing upon earth so white as the whiteness thereof.
And when Jesus had spoken these words he came again unto his disciples; and behold they did pray steadfastly, without ceasing, unto him; and he did smile upon them again; and behold they were white, even as Jesus.
