VATICAN CITY -- If you're not among the millions who have already read "The Da Vinci Code," an Italian cardinal has a plea for you: Don't read it and don't buy it. Genoa Cardinal Tarcisio Bertone, who previously was a high-ranking official of the Vatican's office on doctrinal orthodoxy, told Vatican Radio on Tuesday that the runaway success of the Dan Brown novel is proof of "anti-Catholic" prejudice. Allegations in the novel that Jesus married Mary Magdalene and has descendants have outraged many Christians and have been dismissed by historians and theologians.
