Priesthood

Alma chapter 13 is a great chapter on the priesthood.  In verses 3 & 10 it says:

3 And this is the manner after which they were ordained--being called and prepared from the foundation of the world according to the foreknowledge of God, on account of their exceeding faith and good works; in the first place being left to choose good or evil; therefore they having chosen good, and exercising exceedingly great faith, are called with a holy calling, yea, with that holy calling which was prepared with, and according to, a preparatory redemption for such.

10 Now, as I said concerning the holy order, or this high priesthood, there were many who were ordained and became high priests of God; and it was on account of their exceeding faith and repentance, and their righteousness before God, they choosing to repent and work righteousness rather than to perish;

Being ordained to the office of High Priest doesn’t give you any more priesthood  than being ordained to the office of Elder...  think of the temple: when performing proxy work, they only ordain to the Melchizedek Priesthood, no specific office...  both a high priest and elder have been ordained to the Priesthood after the Order of the Son of God!  Plus, President Nelsen said in 4/18, that the priesthood that the president of the church has is the same priesthood as an elder has...  the difference is only in the keys that the president has, because of his calling...
