When God appeared to Moses in the Burning Bush, he told Moses to remove his shoes because he was on sacred ground.

When LDS people attend a sealing, they are asked to remove their shoes and either wear socks or wear booties.  When a temple open house occurs, the general public puts booties over their shoes, and I’ve been told this is to keep the carpet clean from so many people.  I’ve noticed temple workers wear white shoes, but these shoes aren’t out in the public getting dirty either.

Concerning this issue of removing shoes for a temple sealing, is it because we are on sacred temple grounds, or is it merely to keep the carpets clean?
