And this is where any intellectual credibility you may have ever had on this issue jumps the rails.
Hardly. Maybe among your fellow moon bats and self-appointed Danites.
Neither in accusing him of anything (being essentially an apostate from the Church of Jesus Christ of Latter day Saints), or criticizing his arguments and claims in support of what he's doing, or in challenging his motives and intentions, am I usurping any authority. Indeed, I don't need one speck of priesthood authority, as a Latter day Saint, to criticize his public claims in the public sphere, or to intellectually challenge him in that same public sphere to account for himself, his beliefs, and his aims and goals.
I do, through the oath and covenant of the priesthood, have a responsibility to warn, preach, teach, expound and exhort John Dehlin to cease his project of leading others out of the Church, and supporting cultural Mormonism within it, regardless of whether I'm his immediate priesthood leader or not. If he was sitting in my living room, I would do the same thing, and I wouldn't call up his Bishop or SP to ask permission to disagree with him or call him to repentance as a worthy priesthood holder. That is my right and authority "at all times and in all things, and in all places."
John Dehlin has both email and a phone. Have you contacted him to exhort, expound, and teach him? Or are you simply showboating in public to prove what a righteous tough guy you are to your fellow moon bats and self-appointed Danites? Drop the self-righteous posturing Droopy. We know that your sickly ego is the reason you are here, not the salvation of John Dehlin or anyone else. You exhibit no caring, compassion, selflessness, or Christlike love. You are helping neither yourself nor anyone else. Your pretense at defending the faith is a sham and a denial of Christ's perfect love.
