Or if a unicorn shows up.
OK. 
Which is precisely why we need more news about where the CVs are keeping themselves.
Someone really needs to seduce that chick and fuck her while God watches. #cuckoldjesus
Nice. Just a really, really nice sentiment, there. 'Cause what she wants for her life is not as important as sticking it to the invisible sky-daddy, amirite?
The RCs seem to have taken the Roman bit quite seriously.
I vaguely remember a short story by Conan Doyle which involved sealing a nun into a wall, Vestal Style, but passed it off as anti-papist propaganda.
That played a good part in his essay. But it’s only like, 97% effective.
That’s called an Anchoress, or if male, an Anchorite. I don’t think they have them anymore, but they were quite popular in the early and high Middle Ages. They were consecrated in a ceremony very much like a funeral, and entered a small room attached to a church and never came out again. Often, the wall was sealed, and the Bishop would press his seal into the mortar. They’d spend their time in contemplation and prayer and reading. There was a small slit in the wall for them to receive food and a door through which to pass a chamber pot. They were considered living saints, and many of them died in there during raids or fires, rather than break their vows and leave the room.
(I spent a lot of time in my early adulthood researching the various forms of Consecrated Life available to women within the Church to see if I might have a Calling. They all required chastity, and none of them would allow me the roles accorded to Priests. So I became a Neopagan Priestess instead. Sex is one of our sacraments.

Ah no. This was definitely a punishment unto death, complete with wild-eyed fanatic priest. The girl had either ‘got herself into trouble’, or perhaps even worse veered to the dark prottie side.
As far as the sort you mention are concerned I have a picture book somewhere on monasteries by Sacheverell Sitwell which mentioned those monks in Greece (?) who were sealed in the wall for life, and every now and then put through an arm for tea or food.
In the 1930s or '50s !
People have the darndest idea of what pleases God.
However these ( RCs, not Orthodox ) are the people who brought you the South Baroque in the Souther Germanies and Italy, with skeletal corpses framed amidst the amazing beauty of the mise-en-scene.
The idea of extreme austerity to the point of death wasn’t just a Catholic idea, Buddhists did it too.
Well, I’ve always thought the western monasticism — as distinct from Egyptian Cenobites ( the original christian monks ) — was probably copied from the Far East.
Every people on earth can get together to share culture and belief with open hearts: each can contribute some particular lunacy to make life special.
