The custom in my community is to dedicate Mondays in a special way to St. Paul, our patron.
I was just reading the talk that Pope Benedict gave on St. Paul in a recent general audience. The pope said that Paul gave all his energy to serving Jesus. He added, "From here we draw a very important lesson: what counts is to place Jesus Christ at the center of our lives, so that our identity is marked essentially by the encounter, by communion with Christ and with his Word. In his light, every other value is recovered and purified from possible dross."
