In my post yesterday, I mentioned the possibilities of using sealing power to seal two men together. At the time I was unaware of historical precedent for doing that. I now stand enlightened. Apparently (I would love confirmations on this) men have been sealed together by sealing authority in the Church under a principle called "The Law of Adoption." This is not the same as a homosexual union or marriage. Rather it was a way for two men (likely married to women) to enter into some sort of non-sexual, socially codependent relationship. Even still, the precedent opens up possibilities. It is possible to seal two men together with Priesthood authority.
Perhaps it would be different from exalted marriage, and therefore the eternal posterity would not come to those joined in this type of sealing. (solving the biggest doctrinal obstacle to the practice). I would imagine this fitting into our understanding of exaltation and the hereafter by resulting in two same gendered Celestial Angels sealed together. I'm ok being a Celestial Angel (still a God with divine power, but not a Heavenly Father). What I'm not ok with is being alone for eternity. Couldn't this reconcile that?
There is certainly historical precedence for men exercising creative powers together. Our world was created by Elohim, Jehovah, and Michael, for example (and both Jehovah and Michael were single and disembodied). Thus, a same gendered Godly couple could go around creating worlds. Maybe I'll let my straight God friends populate them for me . . .
