"The Christian belief that God performed a miracle within the Blessed Virgin Mary, causing her to conceive Jesus Christ without being impregnated by human seed. While remaining a Virgin, she gave birth to God Incarnate without the help of any man. Some skeptics claim that Christians copied the Virgin Birth doctrine from pagan religions which told of virgin-born gods and heroes. This article will examine whether or not this charge is true."
