"Vatican newspaper pays tribute to U2. "
The writers are recognizing U2's stong Biblical basis for the words in their songs as well as their heavy emphasis on those things spiritual. Even the titles and themes of each of their albums have a spiritual basis from their conception. It is beautiful to think that this bigger than life band has based so much of their music on the main chords of Chrisitianity. Thanks to Catholic Media Review for a great post.
Enjoy!
