Brothers and sisters, war does not solve any problem: It sows only death and destruction, foments hate, proliferates revenge. War cancels out the future, it cancels out the future. I urge believers to take just one side in this conflict: that of peace. But not in words — in prayer, with total dedication.
I have decided to declare Friday, 27 October, a day of fasting, penance and prayer for peace. I invite the various Christian confessions, members of other religious, and all who hold the cause of peace in the world at heart to participate.
