Pope Benedict XVI has used his first Christmas message to issue a wake-up call to Catholics and to all humanity.
Addressing thousands in St Peter’s Square, the pope said people of the 21st Century risked becoming “victims of their intellectual achievements”.
He decried the “menace” of terrorism, the “humiliation” of worldwide poverty and said pandemics and environmental destruction were dangerous new threats.
