That's still not what it say in Revelations.
It is Revelation, not Revelations. And it still says we are PRIESTS to God the Father. And Jesus Christ is our great High Priest after the order of Melchizedek (as Hebrews says). And Jesus is the ONLY priest in the order of Melchizedek.
The Aaronic and Melchizedek priesthoods in the LDS Church are completely phony. The Aaronic priesthood has been null and void since Jesus rose from the dead, ending the need forever for animal sacrifices. And ONLY Jesus Christ has the Melchizedek priesthood.
So, no, no priesthood disappeared from the earth after the first century, since ALL true believers in the true Jesus Christ of the Bible are a "royal priesthood" to God. So, no one needs the phony priesthoods of Mormonism. They have zero authority, since they teach a different God, a different Savior, and a very different Gospel--which is NO Gospel at all--than what the Bible teaches.
