Christians under siege

My previous blog post was about Christians in India being attacked. Yesterday, 52 Christians were killed during a siege at a Catholic church in the Karada District, Baghdad. A sub-group of Al-Qaeda has claimed responsibility for the killing. The Our Lady of Salvation church was holding mass when a group of armed men began attacking the churchgoers. The Priest was killed. The same church was previously targeted in 2004.
How does one keep the faith after either witnessing or being involved in such an atrocity? We go to church in this country and come away feeling fuelled by the word of God and the companionship of fellow Christians. By contrast with the suffering experienced by Christians in conflict areas our experience on a Sunday seems like pure indulgence. How fortunate we are to be able to experience the peace and love of God in the way that we do.
