I have seen a lot of “neuroses” among clerical and lay Catholics, some of it quite nasty and destructive. A few years ago I went into a parish office to see the pastor and realized as I walked down the corridor that I had passed three people with significant “issues": codependency, out of control control issues, and something I couldn't identify but denial, control, and crippling, morbid obesity were signs.
I don't get upset as much by the illness as by the enabling.
As to why mental problems have arisen, you don't have far to look. Since the early 1900s theories of child—rearing have been abysmal. I've read excerpts from the books. They were inhumane at first. Then the backlash, exemplified by A.S. Neil, took hold and moral neglect replaced emotional neglect.
Then the government started subsidizing single parenthood while mothers thought they ought — indeed some felt bound by a duty to the “sisterhood” — to neglect their children, parking them in kiddie warehouses, from infancy in some cases.
I was head teacher in an “extended care” program in the 70s and I saw parental selfishness to a degree that astonished me.
Pre- or post- Vatican II Catholics seem to share equally in the pain. One of the most apparently devout Catholics I know is an alcoholic, formerly obese, but he got sick (secondary to his obesity), and has no discernible sense of remorse. One of his 8 children has remained Catholic.
His Catholic wife, who “enabled” and denied for decades is now oppressed with crippling depression. The most “traditional Catholic” thing about her is that she gets angry when somebody raises the question of codependency. She toes the cultural Catholic line in her aversion to what has been learned in psychology (which isn't nearly enough, to be sure.) So the problems which arise when the head of the house is an alcohol abusing narcissist just get passed in to the next generation.
To conclude, this article is very wrong indeed.
