The first was deleted because some of us were uncharitable. So lets try this again. I found a non-catholic web page Gaz that talks about a certain priesthood (I cant remember how to type it

) that we were discussing.
gci.org/bible/hebrews7
To me it sounds like it wasnt passed on to anyone. Your thoughts Gaz?
My thoughts…
There is lots of nitpicking that could be done regarding this link. In general, the author argues that the new law requires a new priesthood and that the Aaronic priesthood is not needed. An LDS view would be that the Aaronic priesthood duties changed (since animal sacrifice was abolished) and lineage requirements changed, but the Aaronic priesthood itself was not abolished. The author did not address Exodus 29:9 (“perpetual statute” and all that).
Some nitpicking…
The author refers to the need for a “new” priesthood for a new law, but correctly identifies that new priesthood with Melchizedek who lived hundreds of years before Aaron, so the Melchizedek priesthood is not so new.
The author quotes Hebrews 7:3, which referring to Melchizedek states “Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.”
That verse makes it sound like Melchizedek has no parents!! However, Joseph Smith rides to the rescue!
His correction is “For this Melchizedek was ordained a priest after the order of the Son of God, which order was without father, without mother, without descent, having neither beginning of days, nor end of life. And all those who are ordained unto this priesthood are made like unto the Son of God, abiding a priest continually.”
So it’s the priesthood which had no beginning or end, not Melchizedek (per the Joseph Smith translation.)
An additional LDS insight regarding the true name of the Melchizedek Priesthood…
LDS scripture D&C 107:1-4 states the real name and why it was changed.
1 There are, in the church, two priesthoods, namely, the Melchizedek and Aaronic, including the Levitical Priesthood.
2 Why the first is called the Melchizedek Priesthood is because Melchizedek was such a great high priest.
3 Before his day it was called the Holy Priesthood, after the Order of the Son of God.
4 But out of respect or reverence to the name of the Supreme Being, to avoid the too frequent repetition of his name, they, the church, in ancient days, called that priesthood after Melchizedek, or the Melchizedek Priesthood.
I hope this helps…
