Presents a discussion of re-evangelization and spiritual renewal based on St. Paul's Letter to the Romans. It is neither an exegetical commentary nor a theological treatise, but an attempt to go straight to the heart of what animated the Apostle when he wrote the letter: to build up the faith of the readers and real to them the immense treasures of Christ's redemption. Dealing with the basics of the Christian faith, the Letter to the Romans, besides being an ideal charter for the "new evangelization", is the best basis for that "common witness" among Christians of different denominations that is becoming more and more central to the ecumenical dialogue.
