Today, our Eastern Orthodox brethren celebrate the Feast of the Nativity. Our prayers are with those that celebrate that they may be blessed.
Today Christ is born of the Virgin in Bethlehem. Today He who knows no beginning now begins to be, and the Word is made flesh. The powers of heaven greatly rejoice, and the earth with mankind makes glad. The Magi offer gifts, the shepherd proclaim the marvel, and we cry aloud without ceasing: Glory to God in the highest, and on earth peace, good will among men.
(From the Festal Menaion of the Orthodox Church; hymns from the Third Hour and Matins.)
