That source is garbage. It cites a study estimating the worth of the Church in Australia at A$30bn, uses that number as the global number (though now in US dollars, for no obvious reason), and then spends the rest of the article talking about the finances of the Holy See. And on that matter, it attributes the Vatican's budget deficit to "falling gold prices", as if the Church's main asset was a gold mine that produced a set amount of gold each year - not to mention that gold is up about 50% over the time period they consider, 2013-2022.

I'd expect a more diligently written article from an average ten year old.
