Pope Francis tweeted this week "War never again! Never again war!" and has called for Saturday, September 7 to be a day of fasting and prayer for peace in Syria. A prayer vigil place in St. Peter's Square from 7 p.m. until midnight. September 7 is the Catholic vigil of Mary, the Queen of Peace.
On September 1, the Pope said, “There are so many conflicts in this world which cause me great suffering and worry, but in these days my heart is deeply wounded in particular by what is happening in Syria and anguished by the dramatic developments which are looming, For this reason, brothers and sisters, I have decided to call for a vigil for the whole Church.” [Catholic News Agency]
In calling for the prayer and fasting, the Pope said, "“Let us ask Mary to help us to respond to violence, to conflict and to war, with the power of dialogue, reconciliation and love,” the Pope asked people around the world. “She is our mother: may she help us to find peace; all of us are her children!” [Time]
On the eve of the G-20 summit, the Pope wrote to Russian President Vladimir Putin, "“To the leaders present, to each and every one, I make a heartfelt appeal for them to help find ways to overcome the conflicting positions and to lay aside the futile pursuit of a military solution. Rather, let there be a renewed commitment to seek, with courage and determination, a peaceful solution through dialogue and negotiation of the parties, unanimously supported by the international community.”
