Pope Benedict wants Orthodox Christians to defend traditional church values, warning of threats posed by abortion and gay marriage. The Pope insists that Christian churches walk side by side in this fight.
He urged all Christians to attach great importance to defending the integrity and the uniqueness of marriage between one man and one woman from any kind of misinterpretation.
Meanwhile, in the eastern city of Erfurt a man fired an air gun at a security guard about an hour before a papal Mass. The Pontiff's visit comes as the Catholic church in Germany has been losing thousands of followers following revelations of sex abuse by clergy and church employees.
