Egyptian Coptic Christians enter the Coptic Orthodox Church of St. George to celebrate Christmas Nativity Liturgy, the start of Christmas, on January 6, 2012 in the Brooklyn borough of New York City. Like the Eastern Orthodox Church in Russia, Copts still use the Julian calendar and thus celebrate Christmas on January 7. St. George Church, like other Coptic churches around the country, has witnessed a surge of Christians fleeing Egypt since the start of the Arab Spring. In Egypt human rights groups estimate that as many as 100,000 Copts have left Egypt since the revolution as churches have been burned and Christians increasingly persecuted by the Muslim majority.
