"Any comparison of Matthew 1-2 and Luke 1-2 to pagan divine birth stories leads to the conclusion that the Gospel stories cannot be explained simply on the basis of such comparisons. ... For what we find in Matthew and Luke is not the story of ... a divine being descending to earth and, in the guise of a man, mating with a human woman, but rather the story of miraculous conception without the aid of any man, divine or otherwise. As such, this story is without precedent either in Jewish or pagan literature."
