Any sources about masonic rituals? Or Kirtland temple dedication?

Today in the morning my TBM wife noticed I was not wearing my garments.

I still wear them most days because I don't have real underwear and haven't bought new clothes yet. But I don't use the top garment as often, and she noticed and asked today.

I told her I no longer believe a couple of months ago, but she is processing it. We didn't discuss the garment issue further because I was getting ready for work. But I plan to explain to her later why I don't want to use them. I want to explain to her 2 things:

1._ Most of the endowment ceremony comes from freemasonry

2._ The "sealing power" was restored in a very likely bacchanal party with drunk people in the Kirtland temple.

But the thing is that she is sensible about my sources. Regarding temple endowment, I recently heard a Mormon Stories podcast where they cited the words from masonry ritual, and it is almost the same as temple endowment, but I don't know what source they used. So I was wondering if any of you have a good source. Preferably a source that is not related to mormonism or ex mormonism, only to masonry.

And rewarding Kirtland, any good source about the different testimonies of what happened those days.

If anyone has anything like this somewhere, I would appreciate it very much.

Thank you!!
