Hi Flighter,
Yes it is incredible what people do in the name of religion. The thing about Antarctica though is that you can't just do what you want like in the rest of the world (ish) and the priest would have to be supported for pretty much all of his needs by someone.
So you've raised another question - who is supporting him and why? As Antarctica is peopled only by a transient population who themselves are supported from outside, the arrangements must be somewhat unusual to say the least. The plot thickens...

I have to say it looks much better than the vast majority of Antarctic bases!
