[Invincibly Ignorant]

then God can make a man a priest in a similar irrevocable way.

I see in scripture where God has done this for the tribe of Levi, but where in the NT does it say the office of a priest is irrevocable?

[SoothingDave]

And He breathed on them and said "receive the Holy Spirit, if you forgive men's sins they are forgiven them"

He didn't have no fine print about taking it back if they sinned too bad.
