The Prophet Joseph Smith once taught that “all priesthood is Melchizedek.”  Thus, the restoration of the priesthood can be understood as a series of heavenly events, including a relatively unknown experience with the Lord at Peter Whitmer Sr.’s farmhouse.  In this powerful episode, Dr. Michael Hubbard MacKay explains what happened “in the chamber of old Father Whitmer” (D&C 128:21) and why it matters to our understanding of priesthood.
