Every Wednesday Pope Benedict XVI gives a catechesis at his General Audience. He has given talks on the Apostles and the Church Fathers. These eventually become books.
Lately, during the Year of St. Paul, I have thoroughly enjoyed his talks on the life and teachings of St. Paul. They will eventually be compiled into a book. I just found a website that has them all cataloged.
You can see them all on www.EarlyChristians.org by clicking here. Since these are commentaries with quotes from the pope’s talks, you can read the full text at www.Zenit.org and click on the calendar for the dates when the talks were given.
