This really is an answer to the cavil often heard that, whether true or not, the Virgin birth is not of essential importance. It is not essential, it is urged, to Christ’s sinlessness, for that would have been secured equally though Christ had been born of two parents. And it is not essential to the incarnation. A hazardous thing, surely, for erring mortals to judge of what was and was not essential in so stupendous an event as the bringing in of the “first-begotten” into the world! But the Christian instinct has ever penetrated deeper. Rejection of the Virgin birth seldom, if ever, goes by itself. As the late Prof. A. B. Bruce said, with denial of the Virgin birth is apt to go denial of the virgin life. The incarnation is felt by those who think, seriously to involve a miracle in Christ’s earthly origin. This will become clearer as we advance.
How far Paul was acquainted with the facts of Christ’s earthly origin it is not easy to say. To a certain extent these facts would always be regarded as among the privacies of the innermost Christian circles — so long at least as Mary lived — and the details may not have been fully known till the Gospels were published. Paul admittedly did not base his preaching of his Gospel on these private, interior matters, but on the broad, public facts of Christ’s ministry, death, and resurrection. It would be going too far, however, to infer from this that Paul had no knowledge of the miracle of Christ’s birth. Luke was Paul’s companion, and doubtless shared with Paul all the knowledge which he himself had gathered on this and other subjects. One thing certain is, that Paul could not have believed in the divine dignity, the pre-existence, the sinless perfection, and redeeming headship, of Jesus as he did, and not have been convinced that His entrance into humanity was no ordinary event of nature, but implied an unparalleled miracle of some kind. This Son of God, who “emptied” Himself, who was “born of a woman, born under the law,” who “knew no sin” (Phil. 2:7, 8; Gal. 4:4; 2 Cor. 5:21), was not, and could not be, a simple product of nature. God must have wrought creatively in His human origin. The Virgin birth would be to Paul the most reasonable and credible of events. So also to John, who held the same high view of Christ’s dignity and holiness.
It is sometimes argued that a Virgin birth is no aid to the explanation of Christ’s sinlessness. Mary being herself sinful in nature, it is held the taint of corruption would be conveyed by one parent as really as by two. It is overlooked that the whole fact is not expressed by saying that Jesus was born of a virgin mother. There is the other factor — “conceived by the Holy Ghost.” What happened was a divine, creative miracle wrought in the production of this new humanity which secured, from its earliest germinal beginnings, freedom from the slightest taint of sin. Paternal generation in such an origin is superfluous. The birth of Jesus was not, as in ordinary births, the creation of a new personality. It was a divine Person — already existing — entering on this new mode of existence. Miracle could alone effect such a wonder. Because His human nature had this miraculous origin Christ was the “holy” One from the commencement (Luke 1:35). Sinless He was, as His whole life demonstrated; but when, in all time, did natural generation give birth to a sinless personality?
Doctrinally, it must be repeated that the belief in the Virgin birth of Christ is of the highest value for the right apprehension of Christ’s unique and sinless personality. Here is One, as Paul brings out in Romans 5:12 ff., who, free from sin Himself, and not involved in the Adamic liabilities of the race, reverses the curse of sin and death brought in by the first Adam, and establishes the reign of righteousness and life. Had Christ been naturally born, not one of these things could be affirmed of Him. As one of Adam’s race, not an entrant from a higher sphere, He would have shared in Adam’s corruption and doom — would Himself have required to be redeemed. Through God’s infinite mercy, He came from above, inherited no guilt, needed no regeneration or sanctification, but became Himself the Redeemer, Regenerator, Sanctifier, for all who receive Him. “Thanks be unto God for His unspeakable gift” (2 Cor. 9:15).
