The Story of Jesus' Birth: A Sermon by Martin Luther
The great theologian's powerful reimagining of the Christmas story.
13. Some argue as to how this birth took place, as if Jesus was born while Mary was praying and rejoicing, without any pain, and before she was conscious of it. While I do not altogether discard that pious supposition, it was evidently invented for the sake of simple minded people. But we must abide by the Gospel, that he was born of the virgin Mary. There is no deception here, for the Word clearly states that it was an actual birth.
14. It is well known what is meant by giving birth. Mary's experience was not different from that of other women, so that the birth of Christ was a real natural birth, Mary being his natural mother and he being her natural son. Therefore her body performed its functions of giving birth, which naturally belonged to it, except that she brought forth without sin, without shame, without pain and without injury, just as she had conceived without sin. The curse of Eve did not come on her, where God said: "In pain thou shalt bring forth children," Gen. 3: 16; otherwise it was with her in every particular as with every woman who gives birth to a child.
15. Grace does not interfere with nature and her work, but rather improves and promotes it. Likewise Mary, without doubt, also nourished the child with milk from her breast and not with strange milk, or in a manner different from that which nature provided, as we sing: ubere de coelo pleno, from her breast being filled by heaven, without injury or impurity. I mention this that we may be grounded in the faith and know that Jesus was a natural man in every respect just as we, the only difference being in his relation to sin and grace, he being without a sinful nature. In him and in his mother nature was pure in all the members and in all the operations of those members. No body or member of woman ever performed its natural function without sin, except that of this virgin; here foronce God bestowed special honor upon nature and its operations. It is a great comfort to us that Jesus took upon himself our nature and flesh. Therefore we are not to take away from him or his mother any thing that is not in conflict with grace, for the text clearly says that she brought him forth, and the angels said, unto you he is born.
