I know a couple of women who are deathly afraid of birds. Can you imagine? Did their mothers watch Hitchcocks's "The Birds" too many times during pregnancy? Birds are naturally excellent mothers, as are all members the animal kingdom.
I read an article once years ago, about a woman who was a preacher I think in the 19th c. South, and she was taken to task by male church members for it, who felt it was not a woman's place to try to teach about Christ. She pointed out to them, that only women should teach about Christ, because he was born of a human woman WITHOUT the involvement any human male! You go, girl! So I think Christmas is as much a celebration of Motherhood and the miracle of birth, as of the coming of a savior.
