This Christmas season I’ve been meditating on the Virgin Birth of Christ.
We all know the story. Mary gives birth to a baby boy without the participation of a human father. Some anti-trinitarians charge that this is unseemly—that God the Father, or God the Holy Spirit, had sex with a Jewish teenaged girl. This is of course ridiculous and blasphemous. If Mary had had sex with God, then she wouldn’t be a virgin, would she?
The whole point of the story is that this is a birth unlike any other. God, the Creator, caused an embryo to form in Mary’s womb, and she gestated and bore the baby in the normal way.
I suppose that means that Jesus shared Mary’s DNA—that just as the human authors participated with the divine Spirit in the work of inspiration, so Mary participated in the origin and development of the human Jesus; whom the Bible repeatedly identifies as a “son of David.” But we are not informed of the details.
Why did this happen? Why was Jesus not born, in God’s providence, in the ordinary way?
The Bible doesn’t tell us.
Bishop Ussher, the same man who calculated the Creation to have occurred in 4004 BC, postulated that the Virgin Birth kept the defilement of Adam’s sin from passing to Mary’s baby:
“For sin having by that one man entered into the world, every father becometh an Adam unto his child, and conveyeth the corruption of his nature unto all that he doth beget. Therefore our Savior assuming the substance of our nature, but not by the ordinary way of natural generation, is thereby freed from all the touch and taint of the corruption of our flesh; which by that means only is propagated from the first man unto his posterity. Whereupon he being man of man but not by man, and so becoming the immediate fruit of the womb and not of the loins, must of necessity be acknowledged to be that HOLY THING” (James Ussher, The Incarnation of the Son of God, 12).
Paul Enns, author of The Moody Handbook of Theology, agrees:
“The virgin birth was the means whereby the incarnation took place and guaranteed the sinlessness of the Son of God.”
Charles Ryrie takes exception:
“The Virgin Birth … need not be the necessary means of preserving the sinlessness of Christ, since God could have overshadowed two parents so as to protect the baby’s sinlessness had he so desired” (Basic Theology).
Ryrie goes on to say,
“It served as a sign of the uniqueness of the person who was born.”
Since we get our fallen natures from our mothers as well as our fathers—women are sinners too—Ussher’s thesis seems flawed, and Ryrie appears to be right.
I recently read Mitch Chase’s article “Six Reasons for the Virgin Birth,” which seems to me to handle this particular question well:
”There seems to be a connection between the virginal conception of Jesus and the sinlessness of Jesus. Exactly how that connection exists is debated. … The language of Luke 1:35 doesn’t mean that sin is only biologically transmitted through a human father. Mary was a sinner with a sinful nature. However, the work of the Holy Spirit ensured that the human nature of Jesus in the womb of Mary was holy and without corruption.”
Chase goes on to list other reasons for the Virgin Birth; I commend the entire article for your consideration.
Jesus is the only case of God becoming man. We have trouble understanding unique things, and this is no exception. There is much mystery here. The early church spent 400 years wrestling with the question and never did explain it.
But God has become man, and perfect man at that, and will remain one of us for all time and beyond.
We have much to celebrate and meditate on in these days.
