An addition to the BHT, about the problems with religious authorities.
I believe Joseph Smith, and perhaps his associates, accessed the higher Christian "new covenant" long before the temple ordinances were ever introduced, even as early as the First Vision. The confusion, as I understand it, is that access to that higher covenant is not through carnal commandments and ordinances, not even those within the temple on Earth.
Some Christians and other religious people believe that God is the author of divine law. I don't think this is the case.
