In honor of this Year of St. Paul the magazine "Our Sunday Visitor" has its entire issue available for free online at this link:

I'm really enjoying reading the articles, including regular favorites Carl Olsen and Mark Shea.
They also have a great collection of articles and prayer aids regarding St. Paul, including a prayer card and a poster!
