The Lord did not mention the virgin birth through the pens of St. Paul, St. Mark, and St. John, so if that is considered to be a "flaw", St. Paul is certainly in good company. I believe the Lord Himself chose to remain silent about the matter of His miraculous birth as well. In fact, Isaiah is the only other Biblical author (if memory serves) who talks about it (I will need to check that fact however)!
Here's an article from the Huffington Post. To say that this is a publication that I do not find myself in line with normally would be an understatement of massive proportions, so it's no surprise that I do not agree with most of what this article has to say (especially since the author denies the Virgin Birth), but it does raise an interesting point for this discussion. Here's an excerpt from it (the title below is linked to the entire article):
Did Paul Invent the Virgin Birth?
I am convinced that the idea of Jesus’ birth from a virgin—without a human father—implicitly goes back to the apostle Paul. Paul’s letters date several decades before our New Testament gospels and it is Paul’s understanding of Jesus as the pre-existent, divine, Son of God, that lays the conceptual groundwork for our Christmas stories.
Paul never explicitly refers to Jesus’ virgin birth nor does he ever name either Mary or Joseph. What he does affirm is that Jesus pre-existed before his human birth and subsequently gave up his divine glory through his birth as a human being. He writes that Jesus “though existing in the form of God” emptied himself and took on human form, “being made in the likeness of humankind” (Philippians 2:6-7). He says further “though he was rich, yet for your sake he became poor, so that you by his poverty might become rich” (2 Corinthians 8:9). He has to be referring here, metaphorically, to the “riches” of Jesus’ pre-existence with God, since all our sources have Jesus born of a poor peasant family. Paul also writes “In the fullness of time God sent forth his Son, made of a woman . . .” (Galatians 4:4). The implication of these texts is that Jesus’ mother was merely the human receptacle for bringing Jesus into the world. It is not a far step from these ideas about Jesus’ pre-existence to the notion of Jesus as the first-begotten Son of God—eliminating any necessity for a human father. Paul’s entire message centers on a divine not a human Jesus—both before his birth and after his death. For Paul he is the pre-existent Son of God, crucified, but now raised to sit at the right hand of God. Like the Christian creeds that jump from Jesus’ birth to his death and resurrection in single phrase, entirely skipping over his life, Paul paves the way for a confessional understanding of what it means to be a Christian.
