Eastern Orthodox Metropolitan of Pergamon John Zizioulas
in Rome at the presentation of the encyclical Laudato si'
"The world must see us witnessing to this common faith in Jesus by acting together. We can, and must, work together to protect and preserve our common home: living, teaching and acting in ways that favour a speedy end to the environmental destruction that offends the Creator and degrades his creatures, and building individual and collective patterns of behaviour that foster a sustainable and integral development for the good of all. We can, and must, be united in a common cause to uphold and defend the dignity of all people."
