“Priestly office *may* have been the proximal object, but to make that the point of both the narrative and the Jude reference is Sharptonesque.”
Paying attention to facts is not anything the Rev Sharpton does. The text specifies what he was trying to do: not content with Levitical service, he wanted to be a priest like Aaron.
“For they walked in the way of Cain and abandoned themselves for the sake of gain to Balaams error and perished in Korahs rebellion.”
They tried to justify themselves before God in their own way. They sought financial gain, and sought a role God had not given them. That sounds like a description of the Pope, not a defense of one!
