13 The second priesthood is called the Priesthood of Aaron, because it was conferred upon Aaron and his seed, throughout all their generations. 14 Why it is called the lesser priesthood is because it is an appendage to the greater, or the Melchizedek Priesthood, and has power in administering outward ordinances. 15 The bishopric is the presidency of this priesthood, and holds the keys or authority of the same. 16 No man has a legal right to this office, to hold the keys of this priesthood, except he be a literal descendant of Aaron.
Nobody even asked me if I'm a "literal descendant of Aaron." And I'm not (nobody probably is...Aaron is most likely fictional). Neither were any of my bishops.
So...what gives, mormons? Breaking your own rules??? Again???
The key is the very next verse. The literal descendant of Aaron business refers specifically to the office of bishop. And it says that since high priests in the Melchesidek Priesthood can officiate in the lesser offices; they can serve as bishop if no literal descendant can be found.
Well, Hie, I was taught that literal descendants of Aaron had the rights associated with the priesthood as the Sons of Levi and could choose to be bishops without counselors.
Just to be clear on this, you and I hold the Levi priesthood when we grab the bulge in our jeans. Considering that you were ordained a deacon at age 12, it's altogether right and fitting that you held this priesthood. Aaron's Boner.
