Many of these “nuns” no longer believe in the Real Presence or even the divinity of Christ.
They certainly don’t recognize the authority of the Vatican.
So why don’t they leave?
Because they’re old. The average age of an American woman religious is 70.
These women have no savings or other assets. Obviously they don’t have children who could care for them.
They have Ph.Ds in rarefied subjects with no real world applications, even assuming any company would hire them at their age.
If they stop being nuns, they give up everything.
I always thought that’s what you were supposed to be doing when you took your vows…
