The question of whether or not a woman ought to have her head covered whilst in church is one which tends to raise the temperature of debate within many Christian circles.
Fr Z. (pronounced Zee for some unknown reason) is holding a poll on the issue on his blog.
In the Latin Church it was once obligatory under Canon Law for women to ear a head covering in Church (veil or hat). At present it is not obligatory, but there seems to be a slow resurgence of this tradition. My opinion is that it should be revived. – Father Z.
