Gerald from "The Cafeteria is Closed" posts the holy father's homily. It's a worthy read.
And just in case you're not aware, the holy father's first encyclical, Deus Caritas Est, is being read by some Lutherans, too. That links to the August 2006 issue of the Journal of Lutheran Ethics. It appears that they have follow-up articles for September, but they haven't posted that in a unique URL just yet. Just visit the JLE main page for now and that should show the September issue. In October, when they have updated the main page for October articles, use the option to browse by Issue (by month).
