I had another book by the same author recommended to me some days ago by a person who generally has a talent for finding good books: Torture and Eucharist: Theology, Politics, and the Body of Christ. He wanted to reread it due to the new pope, since it deals with being a church in a society ruled through torture. The examples are from Chile rather than Argentina, but the issues should be the same.
