Upon your first visit through the LDS temple, you will be required to obtain a special “New Name.” You are taken into a tiny room with a worker who gives you the name, with an explanation that you will need to remember and utilize it later in the ceremony. The basis for this name stems from this New Testament verse:
“He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth it.”
Revelation 2:17 (AKJV).
The secrecy behind this name is well understood and emphasized. This New Name with the various handshakes and symbolic gestures you make are required to be given in their perfection if you plan to inherit the highest degree of heaven. The requirement of secrecy stems from the words “which no man knoweth saving he that receiveth it” in the verse above. After that visit, you are never to utter this name again, except if unconnected with the event.
Previously, the commitment was emphasized under the threat of symbolic death penalties for revealing it.
The charade falls on its face as you realize that everyone going through the temple that day shares the same name, and in most cases, everyone shares that name for the particular day of the month.
So much for the applicable New Testament connection.
If you’ve forgotten yours and want to verify it, or wish to know someone else’s name, you can easily find out by visiting the Temple Name Oracle site.
