I think this is a Pope which requires reading the whole interview and not stripped out comments. And then a fruitful discussion can be had. (This is no different than when Bush, Reagan or Palin is headlined and misquoted and then you go read the interview and you discover it's not all as it seems.)
http://www.repubblica.it/cultura/2013/10/01/news/pope_s_conversation_with_scalfari_english-67643118/I read Barnhardt's bio and decided I don't have much use for her. She sounds like she doesn't like the Catholic Church she joined a few years ago and now longs for the way it used to be--some romantic view that existed in the movies of the 40's and 50's and thus sees everything through that lens. She's no different than the liberal Catholics who are pining for the Catholic church they want.
I was discussing this with a young Catholic today-- she explained that the good the Pope references is based on Catholic teaching that the natural law is written on everyone's heart by God --and that if they seek the good they will find it. The good ultimately being God. (I hope I got that right.) So the Pope's use of Good in the interview is about Good capital G not whatever anyone person thinks as good (and feels like doing). At least that's how it seems to me. So a primitive people can seek good as written on their heart by God and never meet a missionary to hear about Jesus. That it is contrary to many Christian beliefs but that is the Catholic view.
Half the interview is spent discussing the saints he likes. ( I don't think Marxists are particularly fond of saints. I pretty sure that the church has canonized people who were killed by Marxists, communists etc.) I find it interesting that Barnhardt failed to mention that part of the interview. She has an agenda and I don't trust anyone who can't address the whole interview.
Several Saturdays ago the Pope held a 4-hour prayer event in St. Peter's square to pray for peace and no war with Syria. That impressed me as he was there the whole time. He didn't just ask everyone to pray he held the event and he stayed for it.
I guess it's my training as a lawyer but one thing I learned way back when was never to believe the case notes (the summary of cases)-- read the dang cases yourself.
