I was thinking about how when I study priesthood in scripture, I find all sorts of grand and surprising facts about the work done by the priesthood power and the promises given to those who do that. But when I see conversations about priesthood, most of those conversations revolve around the day-to-day visible work those with priesthood do nowadays.
I don’t think that priesthood power is meant to be equated with “right to rule in Church positions.” I think it’s something like the Nephites appointing those with the spirit of prophecy to be their war generals. It was just smart. I don’t think that every position that now requires a priesthood holder necessarily would need to, but it made sense to. It was sort of a “why not?” question. Why not have the ward mission leader be a person with the priesthood? (And ideally, everyone with the priesthood understands what that means and seeks the Spirit and so forth.) And same with coorelation. Why not have all the auxillaries work under the direction of the priesthood, especially the highest presidency of the Church?
But remember that in ancient days, the Aaronic priesthood took care of daily sacrifice and so on, and the Melchizedek priesthood usually showed up as a prophet outside of the Church institution. I don’t think that we should ever equate priesthood with leadership.
When we say that the priesthood is the “power and authority” of God, let us not hear “authority” as only a right to have a position in an institutional hierarchy. That is such a reduction of what the priesthood is. Those with the priesthood might also take on callings in the Church, but let us never assume that exhausts the role of the priesthood!
