Christian refugees in a Chaldean Catholic church in Erbil
The Chaldean Patriarch of Baghdad Raphael Louis Sako calls on Iraqi Christians to fast on Christmas Eve in order to implore the Lord for the return of refugees in Mosul and the Nineveh plains. At the same time, he asks the faithful not to organise "any worldly celebration" for Christmas and New Year as "a sign of solidarity with their displaced brothers and sisters, who are going through indescribable suffering."
For this reason, he urges them to fast from Monday 22 December until night on 24 December, not touching food or drink until noon, as "in the days of Ba'utha". The Fast of Ba'utha commemorates what the prophet Jonah brought to the people of Nineveh for their conversion.
"We fast," the Patriarch said, "for the liberation of Mosul and the villages of the Nineveh plains, so that peace and security will return to these areas, and everyone will be able to return to his or her home, job and school." (Source)
