Non-Mormon parents can’t attend their child’s Temple wedding?
That’s creepy.
They usually have a reception following the Temple wedding where everyone has a lot of fun. I’ve been to a few of those and had a blast. No one gets drunk and there’s dancing.
I have never attended a Temple wedding. I hear it’s absolutely holy. It’s not an earthly ordinance. There’s nothing “creepy” about the Temple.
I just remembered something really creepy. When I got married the first time - in a Catholic Church if you can believe it - my mother said she would not attend if my father brought his new wife. Now that’s creepy.
My second marriage, we got married in Reno. That’s kind of creepy too, now that I think of it.
My third and LAST husband - we were married in Mayor Autry’s campaign headquarters right after he won (Fresno).
We hope to be sealed in the Temple some day.
I bet you thought Mormons were better than me, huh?
Non-worthy parents, Mormon or non-Mormon, can't enter the Temple. There is no "wedding" in the Temple, there is a very simple, understated, and brief Sealing ceremony. The Sealing rooms don't hold very many people. Some hold a dozen, some about two dozen at the largest. The Sealing is nothing like a large, traditional wedding that you may be thinking of.
Here's a photo from the LDS Church of one of the Sealing Rooms in the Santiago, Chile Temple.
There's nothing "creepy" about it. Was it "creepy" when the ancient Jews constructed their Tabernacle in the wilderness and limited entry therein? Was it "creepy" when the ancient Jews similarly used Solomon's Temple? Jesus Christ was a Jew and worshipped, taught, etc. in the Temple in Jerusalem. Nothing creepy about it. Entry was limited, especially within the inner walls and the Holy of Holies. Again, nothing creepy about it.
