I think the real question here is who is confused?

I never said there are no nuns.  The article is clear that the US went from a high of 180,000 nuns in the mid 1960's to 49,000 now and that 90% of the current nuns are older than 60.  That doesn't say there are no nuns.  It does say there are a lot less nuns now than 50 years ago and that most of the nuns now are significantly older.  

The question isn't about whether there are nuns or even if they're visible, as you seem to be arguing.  The question the article raises is why the precipitous fall in vocations?

We actually agree God doesn't need nuns.  Where I think you're confused is WE (not God) could continue to benefit from nuns.  They have not been supplanted by other people and workers.  Health care and education both have unmet needs that nuns could meet.  As for unions, your argument is non sequitur (again) and a primary reason for unions is to assure fair pay, something you seem to miss.

I think you're confused, not me.<g>
