The vision of Elijah is one of the most important Church history events in all of the Doctrine & Covenants. It’s the vision where Elijah came to Joseph and Oliver and restored the sealing power. Did you know that Joseph was sealed to his first plural wife, Fanny Alger a year or two prior to that? We asked Dr. Mark Staker how to explain that, and I think you’ll find his explanation very interesting. He makes a distinction between priesthood keys, and priesthood, and indicates the sealing power may have been revealed as early as 1830!
