Aren’t Miracles Impossible?

Of the four canonical gospels, there are two, Matthew and Luke, that provide details about the birth of Jesus. The accounts may reflect the unique perspectives of both Joseph (in Matthew’s gospel) and Mary (in Luke’s), for there are many differences between the two.{1} However, of the things they share in common, one cannot be missed. They both declare that Jesus was miraculously conceived through the supernatural intervention of the Holy Spirit in the womb of a young virgin named Mary.{2} Today, some scholars regard the doctrine of Jesus’ virgin birth as simply a legendary development of the early church. The story is said to be myth–not history.{3} But if we ask why they think this, we may notice something very interesting. For the virgin birth is usually not rejected on grounds of insufficient historical evidence. Rather, it is more often rejected on the presupposition that miracles are simply impossible.{4} This is quite revealing. For if such scholars really believe that miracles are impossible, then no amount of evidence can convince them that one has actually occurred. Their minds are made up before they examine the evidence. In theory, they view miracle claims as guilty until proven innocent. In actual practice, however, they never reach a verdict of “Not Guilty”!

The belief that miracles are impossible often arises from a naturalistic worldview. Strict naturalism completely rejects any notion of the supernatural.{5} All that exists are atoms and the void.{6} If naturalists are right, it follows that miracles are indeed impossible. While strange things that we do not fully understand may sometimes occur, there must, in principle, be a naturalistic explanation for every event in the universe.

But are such naturalists right? Since my aim in this article is to explore the historicity of Jesus’ virgin birth, I will not attempt now to refute naturalism. Instead, I will simply point out that if a personal Creator God exists (and there is good evidence to believe that One does), then miracles are at least possible. For clearly, such a God might choose to intervene in His creation to bring about an effect for which there was no prior natural cause. And that is at least one way of describing a miracle.

Thus, if a personal Creator God exists, miracles are possible. And if miracles are possible, then Jesus’ virginal conception and birth are possible. And if the virgin birth is possible, then the only way we can determine if it actually occurred is by carefully examining the evidence both for and against it. Next we will continue our inquiry by looking at an ancient prophecy that some think actually foretold Christ’s virgin birth!

Didn’t Matthew Misread Isaiah?

Matthew’s gospel tells us that Jesus was conceived through the supernatural agency of the Holy Spirit while Mary was still a virgin.{7} He then goes further, however, by declaring that this miraculous event fulfilled an Old Testament prophecy in the book of Isaiah. He writes:

Now all this took place that what was spoken by the Lord through the prophet might be fulfilled, saying, “Behold, the virgin shall be with child, and shall bear a son, and they shall call his name Immanuel,” which…. means, “God with us.”{8}

Some scholars are unimpressed with Matthew’s interpretation of Isaiah. John Dominic Crossan unequivocally states, “The prophecy in Isaiah says nothing whatsoever about a virginal conception.”{9} Did Matthew misread Isaiah?

Let’s acknowledge that the original context of Isaiah’s prophecy may not be exclusively about the virginal conception of Jesus. The year is 734 B.C. and King Ahaz of Judah is terrified to learn that Aram and Israel have formed an alliance against him. Isaiah is sent to reassure Ahaz that God is in control and that the aims of the alliance will not succeed. Ahaz is told to request a sign from the Lord, a means of confirming the truth of Isaiah’s message. But he refuses!{10} Annoyed at the king’s stubbornness, Isaiah declares that the Lord will give a sign anyway: an almah (a maiden of marriageable age) will conceive a son and call his name Immanuel. He will eat curds and honey upon reaching an age of moral discernment. But before this happens, the land of the two dreaded kings will be forsaken.{11} Should this prophecy be understood to refer exclusively to Jesus’ virginal conception? If so, how does it relate to the promise that the Aram-Israel alliance would soon be broken and their lands forsaken (a promise fulfilled within twelve years time)?{12}

It’s quite possible that Isaiah’s prophecy had a dual fulfillment:{13} initially, in Isaiah’s day; and ultimately, at the birth of Jesus. In this view the almah, or young maiden of Isaiah’s prophecy, is a type of the virgin Mary, who later conceived Jesus through the miraculous intervention of the Holy Spirit.{14} So although a young woman in Isaiah’s day bore a child named Immanuel, Jesus is later recognized by Matthew to also be Immanuel, “God with us” in a new and unprecedented way. Thus, Matthew didn’t misread Isaiah. And if this is so, we must continue to consider this prophecy in weighing the evidence for Jesus’ virgin birth.

But even if we’ve correctly explained Matthew’s use of Isaiah’s prophecy, we must still consider the alleged contradictions in the infancy narratives of Matthew and Luke. We will address this issue in the next section.

Don’t Matthew and Luke Contradict Each Other?

{15} Some scholars see the infancy narratives in Matthew and Luke as contradictory. If so, their historical reliability is in doubt, along with their accounts of Jesus’ virgin birth. But are these narratives really contradictory? Let’s take a closer look.

First, some think Matthew implies that Mary and Joseph resided permanently in Bethlehem before Jesus’ birth, whereas Luke says they lived in Nazareth and only came to Bethlehem for the census.{16} But Matthew never actually tells us the couple’s residence before Jesus’ birth. He simply says that Jesus was born in Bethlehem, just like Luke.{17}

But if Mary and Joseph resided in Nazareth prior to Jesus’ birth, then why, after their flight into Egypt, does Matthew seem to suggest that they intended to return to Judea rather than their home in Nazareth?{18} It’s helpful to recall that Jesus was “the promised king of David’s line.”{19} Might not his parents, then, have wished to raise Him in His ancestral home?{20} This is actually quite probable. But regardless of their original intention, let’s not forget that Matthew goes on to write that Joseph, being warned in a dream not to settle in Judea, did take his family back to Nazareth after all.{21}

Finally, some think Luke’s narrative leaves no room for Matthew’s account about the visit of the magi and sojourn in Egypt. These events could only have occurred after Jesus’ presentation in the Temple, forty days after His birth.{22} But Luke 2:39, which concludes this presentation, says that when Jesus’ parents “had performed everything according to the Law of the Lord, they returned to . . . Nazareth.” This raises a question. Does Luke’s statement prohibit an initial return to Bethlehem, thus casting doubt on Matthew’s account of the magi and flight into Egypt?

It’s important to notice the emphasis in Luke 2:39. It’s not so much on when Mary and Joseph returned to Nazareth, but rather that they did not return until after they had fulfilled the requirements of the Law.{23} Strictly speaking, Luke 2:39 does not disallow the events recorded by Matthew. Luke may not have known of the visit of the magi and flight into Egypt, or he may have chosen to omit this information. Either way, however, “the silence of one narrative regarding events recorded in another is quite a different thing from actual contradiction.”{24} Thus, the virgin birth cannot be dismissed on the grounds that the infancy narratives are contradictory–they’re not.

But aren’t we forgetting the most obvious hypothesis of all? Is the story of Jesus’ virgin birth simply a myth, comparable to other such stories from the ancient world? We’ll examine this question in the next section.

Wasn’t the Virgin Birth Story Derived from Pagan Myths?

Not long after Matthew and Luke finished writing their gospels, some scholars began contending that the story of Jesus’ virgin birth was derived from pagan myths. Unfortunately, such ideas continue to haunt the Church even today. John Dominic Crossan cites parallels between the deification of Octavius by the Roman Senate and that of Jesus by the early church.{25} In each case, says Crossan, the decision to deify their leader was closely connected with the invention of a divine birth story. The official biography of Octavius claimed the god Apollo in the form of a snake impregnated his mother.{26} Jesus’ biographers claimed the Holy Spirit in the womb of the virgin Mary conceived Him. In Crossan’s view, neither story is historically true: “The divine origins of Jesus are…just as…mythological as those of Octavius.”{27} The stories simply help explain why these men received divine honors.

Is Crossan’s hypothesis plausible? One can certainly find scholars who embrace such ideas. But a careful comparison of the biblical accounts of Jesus’ birth with the many miraculous birth stories in pagan literature reveals several important differences.

First, the accounts of Jesus’ virgin birth show none “of the standard literary marks of the myth genre.”{28} Matthew and Luke are written as history–not mythology. They mention places, people, and events that can be verified through normal methods of historical and archaeological inquiry. The beginning of Luke’s gospel “reads very much like prefaces to other generally trusted historical and biographical works of antiquity.”{29} Thus, there is a clear difference in genre between the gospels and pagan myths.

Another difference can be seen in the religious atmosphere of these stories. The pagan myths are polytheistic; the gospels, monotheistic. The miraculous birth stories in pagan literature usually focus on a god’s lust for some mortal woman.{30} Since this lust is typically gratified through sexual intercourse, the resulting conception and birth are hardly virginal. We are thus far removed from the description of Jesus’ virginal conception in the gospels. There we find no hint that God’s love for Mary in any way parallels the lust of Apollo for the mother of Octavius.

These are just two of many differences between the gospel accounts of Jesus’ birth and the miraculous birth stories in pagan literature. But even these differences make the theory of pagan derivation unlikely. Remember, this theory requires us to believe that strict moral monotheists, who claimed to be writing history, borrowed some of the crudest elements from polytheistic myths to tell the story of Jesus’ birth! Frankly, it’s incredible. But could a theory of Jewish derivation still work? We’ll conclude with this question.

Wasn’t the Virgin Birth Story Derived from Jewish Thought?

Some scholars have speculated that the story of Jesus’ virgin birth may have been derived from an imaginative Jewish interpretation of the Old Testament.{31} The story is not historical; it is a literary fiction of early Jewish Christians. It may have resulted from reflection on Isaiah 7:14, which says in part, “Behold, a virgin will be with child.” What could be more natural than this verse becoming the source of inspiration for a legendary tale about the virgin birth of the Messiah?{32}

But would this really have been natural? There’s actually no clear evidence that pre-Christian Judaism understood Isaiah 7:14 as a prophecy of the Messiah at all, much less his virginal conception.{33} Indeed, many contend that the Hebrew text of Isaiah says nothing whatever about a virginal conception and birth.{34} But if that is so, it would seem quite unlikely for early Jewish Christians to have read the verse in such a way!

Others believe the translation of Isaiah from Hebrew to Greek, known as the Septuagint, may have provided the initial impulse for such a reading. The Greek text of Isaiah 7:14 translates the Hebrew term almah, meaning “a young woman of marriageable age,” with the Greek term parthenos, meaning “virgin”. Could this translation have led some Jewish Christians to conclude that Isaiah was prophesying the virgin birth of the Messiah? And if so, might they have invented the story of Jesus’ virgin birth as the alleged “fulfillment” of Isaiah’s prediction?

While one can claim that they might have done so, there’s no evidence that they actually did. But if not, what could account for early Christianity’s understanding of Isaiah 7:14 as a prophecy of the Messiah’s virgin birth? Well, the historical reality of Jesus’ virgin birth could have done so! After all, it’s one thing to think that early Jewish Christians, without any precedent in Jewish thought, would invent the story of Jesus’ virgin birth from an imaginative interpretation of Isaiah’s prophecy. But it’s another thing entirely to think that by beginning with a historically reliable account of Jesus’ virgin birth, they eventually concluded that Isaiah had indeed prophesied such an event.{35}

Only the latter hypothesis is supported by evidence. Particularly important in this regard are the gospels of Matthew and Luke. These sources have been shown to be quite historically reliable. Their accounts of Jesus’ birth, though apparently written independently of one another, are free of contradiction. Indeed, apart from an unproven bias against the supernatural, there is little reason to doubt the accuracy of their reports. Thus, there do appear to be adequate grounds for believing that Jesus really was born of a virgin!


1. Such differences do not, of course, imply contradictions. See the third section for more information.

2. See Matt. 1:18-25 and Luke 1:26-35.

3. For instance, John Dominic Crossan, Jesus: A Revolutionary Biography (San Francisco: Harper, 1994), writes, “I understand the virginal conception of Jesus to be a confessional statement about Jesus’ status and not a biological statement about Mary’s body. It is later faith in Jesus as an adult retrojected mythologically onto Jesus as an infant. . .” (23). And again a little later, “Jesus . . . was born . . . to Joseph and Mary.” (26)

4. For example, in Paul Copan, ed., Will the Real Jesus Please Stand Up? A debate between William Lane Craig and John Dominic Crossan (Grand Rapids, Michigan: Baker Books, 1998), 61, Dr. Craig questions Dr. Crossan about his anti-supernaturalistic presuppositions and whether they do not rule out the possibility of miracles a priori. Dr. Crossan admits that, insofar as miracles are concerned, “[I]t’s a theological presupposition of mine that God does not operate that way.”

5. Ibid. In fact, although it is difficult to pin him down this appears to be Dr. Crossan’s position. At one point in the debate, Dr. Craig asks Dr. Crossan, “What about the statement that God exists? Is that a statement of faith or fact?” Dr. Crossan responds, “It’s a statement of faith for all those who make it” (49). But suppose no human beings existed to make such statements of faith. In order to clarify Dr. Crossan’s response, Dr. Craig later asks, “Was there a being who was the Creator and Sustainer of the universe during that period of time when no human beings existed?” Dr. Crossan’s answer is quite revealing: “Well, I would probably prefer to say no because what you’re doing is trying to put yourself in the position of God and ask…’How is God apart from faith?’ I don’t know if you can do that. You can do it, I suppose, but I don’t know if it really has any point” (emphasis mine, 51). This answer appears to commit Dr. Crossan to an atheistic (and thus strictly naturalistic) worldview.

6. So said the famous Greek atomist philosopher, Democritus of Abdera.

7. See Matt. 1:20-25.

8. Matt. 1:22-23.

9. Crossan, Jesus: A Revolutionary Biography, 17. He goes on to say, “Clearly, somebody went seeking in the Old Testament for a text that could be interpreted as prophesying a virginal conception, even if such was never its original meaning”(18).

10. See Isaiah 7:1-12.

11. See Isaiah 7:13-16.

12. Charles Caldwell Ryrie, The Ryrie Study Bible (Chicago: Moody Press, 1978). Ryrie comments, “Within twelve years after this prophecy, Damascus was captured by Assyria (732) and Israel had fallen (722).” (1024)

13. Although some writers object to the notion of a “dual fulfillment” of prophecy, there appear to be other examples of this phenomenon in Scripture. For instance, in Joel 2:28-32 we find a promise of a future outpouring of the Holy Spirit. The prophecy is linked with various cosmic disturbances that will immediately precede the Day of the Lord. Later, in connection with the coming of the Holy Spirit on the day of Pentecost in Acts 2, Peter declares, “This is what was spoken of through the prophet Joel” (v. 16). He proceeds to quote almost the entire passage of Joel 2:28-32. However, it seems that only the first part of the prophecy, concerning the outpouring of the Holy Spirit, was actually fulfilled in Peter’s day. What’s more, the book of Revelation seems to indicate that the cosmic disturbances mentioned by Joel await a yet future fulfillment (see Rev. 6:12). While scholars have offered various solutions to account for Peter’s use of Joel in Acts 2, it seems best to understand Joel’s prophecy as having some sort of “dual fulfillment”: an initial fulfillment on the day of Pentecost; an ultimate fulfillment before the second coming of Christ. The “dual fulfillment” view has the advantage of preserving the original integrity of the prophet’s message, while at the same time recognizing that some prophecies may be Divinely intended to include more than one fulfillment throughout salvation history. In light of this very real possibility, we should humbly acknowledge that Matthew’s use of Isaiah and Peter’s use of Joel confront us with complex interpretive issues. It is partly for this reason that very capable scholars reach different conclusions about the meaning of these passages. After careful consideration I was inclined toward the “dual fulfillment” position; however, I recognize that others will want to adopt some other perspective.

14. Ryrie, The Ryrie Study Bible, 1024.

15. In this section I have relied heavily on the analysis given in J. Gresham Machen, The Virgin Birth of Christ, (Grand Rapids, Michigan: Baker Book House, 1971), 192-97.

16. I have chosen to examine some of the more difficult “contradictions.” But it’s important to point out that some of the alleged difficulties are quite easily dealt with. For instance, Luke records that shepherds visited the baby Jesus in response to an angelic announcement (Luke 2:8-20). Matthew, however, tells not of shepherds but of magi, who responded not to an angelic announcement, but to an astronomical observation (Matt. 2:1-12). But surely there’s no contradiction here. After all, it’s entirely possible that both the shepherds and the magi visited Jesus! Doubtless the accounts are selective and have not recorded every detail, but this does not mean they are contradictory.

17. Matt. 2:1; Luke 2:1-7.

18. Matt. 2:19-23.

19. Machen, The Virgin Birth of Christ, 193.

20. Ibid.

21. Matt. 2:22-23.

22. Machen, The Virgin Birth of Christ, 196, explains: “The visit of the magi could hardly have taken place during this forty-day interval; for it would have been impossible to take the child into the Temple when the wrath of the king was so aroused…Evidently, therefore, the flight into Egypt took place immediately after the magi had come; no visit to the Temple could have intervened. If, therefore, the two narratives are to be harmonized, we must suppose that when the presentation in the Temple had been completed, Joseph and Mary returned with the child to Bethlehem, received there the visit of the magi, and then fled into Egypt.”
