The connection between the appearance of the pre-mortal Messiah to the brother of Jared is directly connected in Moroni’s mind with the appearance of the resurrected Messiah to the Nephites. This is the same person, the same Messiah. He is in a similar form, and he does similar things. Although Moroni does not tell us specifics, he does tell us what he considers most important, and that is that what this Messiah does is the same. It is important for Moroni to let us know that this Messiah is the same throughout the ages, and that when he ministers to men in these rare appearances, he does the same things. Since this is the Messiah that is yet to come in our future, Moroni is telling us some of what we may expect. We may expect the human form, and we may expect the kind of ministrations that he performed as recorded in the 3 Nephi.
