The priest gave a good sermon on it the other day but I barely remember it now.
It was based on a lot of the life affirmation, being mode, opposing death drives thinking that Erich Fromm was big on, even though Fromm was a non-theist and Jewish there's a lot of similarities in some of the thinking, at least so far as this life goes etc.
I bought a book written by a monk yesterday called Freedom from Evil Spirits, its pretty much a play on words as it discusses psychological health, then it discusses over coming addiction and then it discusses "spirit" in the sense of pervasive beliefs that can possess someone if they are unwary, like being possessed by a zeitgeist or something like that.
There was a time that I worked closely with a group of Jesuits in Dublin, their order requires them to have a profession besides the priesthood, many of them were teachers but they were also doctors (medicine) and psychotherapists or analysts, there were some similarities with confession, Freud even said so himself in one of his books.
