Last Sunday, for the first time in 1600 years, no mass was celebrated in Mosul. The Islamic State of Iraq and Syria (ISIS) seized Iraq’s second largest city on June 10, causing most Christians in the region to flee in terror, in new kinship with the torment of Christ crucified on the cross. The remnant of Mosul’s ancient Christian community, long inhabitants of the place where many believe Jonah to be buried, now faces annihilation behind ISIS lines. Those who risk worship must do so in silence, praying under new Sharia regulations that have stilled every church bell in the city.
