Something for those who think Christianity and Islam are deeply divided, a holiday card greeting I received from Adel bin Ahmed Al-Jubeir, Ambassador of Saudi Arabia to the United States:
In the name of God, Most Compassionate Most Merciful,Behold, the angels said:
"O Mary, God giveth thee glad tidings of a Word from Him:
his name will be Christ Jesus, the son of Mary, held in honour in this world and hereafter and of (the company of) those nearest to God;
-- Aurat Al-i-Imran, Holy Quran
I'm a devout secularist, but it's good in this season to be reminded of the deep ties between cultures which some use to divide.
