CAIRO — Egypt’s minority Christians marked their first Christmas after the election of an Islamist president and a new Coptic Christian pope — and after adoption of a constitution many believe has an Islamist slant.

Christians converged on Cairo’s main cathedral Sunday for Midnight Mass on the eve of Orthodox Christmas led by their new pope. Pope Tawadros II was elected in November to replace longtime Pope Shenouda III, who died in March after 40 years as the leader of the church.
