Papa Ratzinger Forum has a translation of the Pope's address after a performance by the Berlin Philharmonia Quartet on November 18. Catholic News Agency has an article about the performance and the Pope's address. An excerpt from Papa Ratzinger Forum:
"In effect, we can imagine the history of the world as a marvelous symphony that God has composed and whose execution He Himself leads as a wise orchestra conductor. Even if to us, the score may often seem complex and difficult, He knows it from the first to the last note.
"We are not called on to take the baton into our hands, much less to change the music according to our taste. But we are called, each in his place and according to his capacity, to collaborate with the great Master in executing his stupendous masterpiece. And in the course of its execution, we would also be given gradually to understand the great design of the Divine score."
