So what?
Debatable, but again, so what?
I need to see how this is an enduring principle that the New Testament isn't meant to overcome,
What?
because that's my view, and I don't see any scripture in necessary conflict with my view.
Argument from incredulity is a fallacy.
What is your evidence supporting this claim? I grant that there were a lot of wicked priests but I stop short of therefore believing that "the majority" of them were.
God told the Levites that they would serve Him for eternity (Deuteronomy 18:5), and then, later, He ended their service to Him because of how wicked they had become. (1 Samuel 2:30-31)
Was it an actual numerical majority,
No number is given, but the implication is that it was more than half of Israel that rejected her Messiah.
At least three cities are named by Jesus Himself as being unrepentant. despite Him doing most of His miracles in those three cities. Did some in those cities repent? Sure, I have no doubt that at least a few did. But the fact is that, as a whole, those cities rejected Him, and did not repent.
Did some in Israel repent, and accept Christ as their Messiah? Sure, but it wasn't enough for God to consider Israel as having accepted Him.
or was it only a majority of their leaders, with many others, but not necessarily a majority?
No, Paul talks about Israel as a whole (minus the remnant of course) as having rejected her messiah.
You said, " Jesus said the majority is evil, wicked." What was I supposed to think?
That He was correct.
No, it's not. A man cannot have two masters:
“No one can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon. - Matthew 6:24

What I said stands: Your commitment should be to God and His word, not a political entity, for God is eternal, and eternally good and just, but political entities, and even non-political entities, such as churches, businesses, and institutions, grow corrupt. When (not if) they do, your commitment to God should be your priority. But you're holding on to a commitment to a political entity that has already become corrupt...
Doug McBurney, on a recent show of The Weekly Worldview, referenced a passage from C.S. Lewis's
The Great Divorce. I won't spoil the show for you, you can listen to it
here, but I want to point out that you're like the man in the portion of the story that Doug tells from the book.
