I realize the encyclical is old news but I just ran across this article. Here is George Weigel's take on the new papal encyclical. He calls it a "duck-billed platypus", with clearly demarcatable sentences written by Benedict and those written by the Pontifical Council for Justice and Peace with a decidedly more liberal slant. And here is Jimmy Akin's critique of George Weigel's critique of the encyclical. He mostly agrees with him but not entirely; he doesn't buy that the PCPJ texts don't reflect Benedict's thought. Akin also relates his first impressions of the encyclical.
I'll repeat my usual complaint about encyclicals: Why can't these things be clear, lucid, and readable to ordinary people (in other words, at the risk of not being perspicacious, perspicacious)? Why do they always have to be impenetrable and abstruse? Both Weigel and Akin comment on how hard-to-read this encyclical is.
