Can a true Christian deny the virgin birth? This question would perplex the vast majority of Christians throughout the centuries, but modern denials of biblical truth make the question tragically significant. Of all biblical doctrines, the doctrine of Christ's virginal conception has often been the specific target of modern denial and attack.
Attacks upon the virgin birth emerged in the aftermath of the Enlightenment, with some theologians attempting to harmonize the anti-supernaturalism of the modern mind with the church's teaching about Christ. The great quest of liberal theology has been to invent a Jesus who is stripped of all supernatural power, deity, and authority....
Another angle of attack on the virgin birth has come from the group of radical scholars who organize themselves into what is called the "Jesus Seminar." These liberal scholars apply a radical form of interpretation and deny that the New Testament is in any way reliable as a source of knowledge about Jesus....
Can a true Christian deny the virgin birth? The answer to that question must be a decisive No. Those who deny the virgin birth reject the authority of Scripture, deny the supernatural birth of the Savior, undermine the very foundations of the Gospel, and have no way of explaining the deity of Christ....
Christians must face the fact that a denial of the virgin birth is a denial of Jesus as the Christ. The Savior who died for our sins was none other than the baby who was conceived of the Holy Spirit, and born of a virgin. The virgin birth does not stand alone as a biblical doctrine, it is an irreducible part of the biblical revelation about the person and work of Jesus Christ. With it, the Gospel stands or falls.
