Let me bring up that term "anachronism" again. The year is 2017, and we are well into the 21st Century.
The last Index of Forbidden Books was published by the Catholic Church in 1948, and the Index was abolished altogether in 1966.
Jim refers at length to a document on dancing written by an Irish archbishop in 1925, and I haven't been able to understand the relevance of that document.
I appreciate the book recommendations for their historical interest, but not for their current relevance. The Tailor and Ansty (1942) was banned by the Irish Censorship of Publications Board, but not by the Catholic Church. I'm sure the works of John B. Keane are interesting, so thanks to Raggytash for recommending The Bodhran Makers (1986) and Letters of a Matchmaker (1975).
But as an American, I see these publications as 40 to 90 years old, and I can't see how anyone can use them as basis for a condemnation of the current situation of the Catholic Church. Maybe long grudges is what Ireland is all about, though. I had a run-in with a Cork-born priest in the 1980s, and then didn't see him for 25 years. He became pastor of my parish in 2005, and proceeded to make me miserable until he finally went back to Cork last year. He'll be back for the next month, so I plan to steer clear of the bastard.
