"Headcovering in the Orthodox church?" is a short discussion of the practice of headcovering in the Orthodox churches, found in the Beliefnet.com forums. The consensus there seems to be that it depends on the jurisdiction, the particular church, and the individual woman. It is also pointed out in other entries that the practice is found in the Bible and in antiquity (while wearing dresses versus pants is not).
Also, please stop by "Light and Good Order", for more information and lovely illustrations of headcovering in the Orthodox churches, and don't miss reading/watching "Free to Cover" for another sweet personal journey (often with photos) in headcovering in the Orthodox tradition.
