I've never heard any true Catholic exorcising their home. None.
I just wrote that it wasn’t an exorcism. But it was a wish, a hope and a prayer that evil would cease to exist within the house if it was present. I am writing about the Irish Catholics of New York City of my youth which is why I used the word “ethnic.” I doubt Catholic intellectuals of the “Brideshead Revisited” type or the Protestant-style American Catholics of today know what I’m talking about or indulge in such thought.
Many Catholics have had their homes blessed by a priest. Just because you haven’t heard of it, doesn’t mean that it doesn’t happen.
