Protestants, mostly. Leftists, too. But the wealth is just an excuse. It's bus fare on the world scale. The main envy is of the Vatican's stature as an institution whose message can't be ignored, after being written off so many times in 2000 years.
But you knew that.
As a Protestant myself, I can tell you that you're grossly mistaken. It isn't about wealth. It's about Jesus Christ. Therefore, I'll ask again: why would any Christian envy the wealth of the Catholic church, when that is not what matters?
"Leftists, too."
Ah, so you group non-Catholics with leftists. Revealing, that.
" But the wealth is just an excuse. It's bus fare on the world scale. The main envy is of the Vatican's stature as an institution whose message can't be ignored, after being written off so many times in 2000 years."
Your priorities are in error; they cloud your thinking. It's not about your denomination, nor your church, nor your traditions, nor your "institution." It's about the Lord Jesus Christ, who gave His life so that we could live eternally with Him.
Anyone who comes to Him, Catholic or not, receives that grace and that gift. Yet you think folks are worried about the Vatican's treasures.
Wow.
"But you knew that."
What I know is that you seem to have a problem with misplaced pride. Remember the Scriptures---and there are a few---which instruct us to boast about nothing but the Lord.
