Mary's story
With characteristic attention to the role of women, Luke tells the story through Mary's eyes. In Luke's account, we learn that God sent the angel Gabriel to Mary in Nazareth. Gabriel said to her: "Do not be afraid, Mary, you have found favor with God. You will be with child and give birth to a son, and you are to give him the name Jesus" (Luke 1:30-31).
How could this be, Mary asked, as she was a virgin? Gabriel explained that this would not be a normal conception. "The Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God" (verse 35).
Even though her pregnancy would surely be misunderstood and put her reputation at risk, Mary courageously accepted the extraordinary situation. "I am the Lord's servant," she declared. "May it be to me as you have said" (verse 38). By a miracle, the Son of God entered into time and space and became a human embryo.
The Word Became Flesh
Those who believe in the Virgin Birth usually believe that God became flesh for our salvation. Those who do not accept the Virgin Birth are inclined to understand Jesus of Nazareth as Human being----and only a human being.
The doctrine of the Virgin Birth is directly related to, but not identical with, that of Incarnation. The Incarnation (literally, "embodiment") is the doctrine affirming that the eternal Son of God added human flesh to his divinity, and became man. This belief finds its clearest expression in the prologue to John's Gospel: "The Word became flesh and made his dwelling among us" (John 1:14).
The doctrine of the Virgin Birth states that the conception of this man Jesus was miraculous, in that he had no human father. The Incarnation says that God became flesh; the Virgin Birth tells us how.
The Incarnation was a supernatural event. It, therefore, needed to involve a special kind of birth. If the child to be born was merely human, there would have been no need for a virgin birth. The first man, Adam, for example, also came miraculously from the hand of God. He had neither father nor mother. But Adam was not God. God chose to enter into humanity----"enflesh" himself----by means of a miraculous Virgin Birth.
Late Origin?
As we have seen, the wording of the passages in Matthew and Luke is clear and unambiguous: Mary was a virgin when Jesus was conceived in her womb by the Holy Spirit. It was a miracle of God. But with the rise of liberal theology----with its general suspicion of everything miraculous----these clear biblical statements have increasingly come to be challenged on a variety of grounds.
Among them is an alleged late origin of the birth accounts. This theory argues that as early Christians beliefs about Jesus developed, Christians began to add fictional elements to the basic story of Jesus' life. The virgin Birth, we are asked to believe, was simply their imaginative way of saying that Jesus Christ was God's gift to humankind.
