I have serious doubts how much the ex-wife could even be considered human.
I have three. I call them the Fates: Minnesotan Lutheran, Korean Buddhist, and Jewish atheist, in that order. There's probably a narrative arc there.
...but while the Protestant can just conduct that business inside her own head, she finds it much easier than the Catholic would who does not have the direct access to her invisible friend but rather has to go through a human intermediary to whom she must vocalize and describe what she's "done wrong", whom she can feel passes judgement on her, and who gives her some kind of punishment. A Protestant's invisible friend never passes judgement on her (unless she feels that he should) and never punishes her (unless she feels that she should, but that's her own mental health issue). So receiving forgiveness is a lot easier and less bothersome for a Protestant than for a Catholic.
I considered the impact of the confessional and came to similar conclusions.
Does that help your research any?
Alas, these are all historical questions now. Looking back, I see I approached the question like an early 19th century British gentleman naturalist: a keen eye, lots of enthusiasm...but statistically naive; still, anything for science.
