I think this was an area of some disagreement in the early church. Only two Gospels speak of the virgin birth (Matthew and Luke). Paul never speaks of it in his epistles, but does say that he is of the Davidic line (Romans 1:3)
Matthew and Luke explain their position by challenging the interpretation that Jesus was a descendant of David:
Luke 20:41–21:4 Then Jesus said to them, “How is it that they say the Christ is the Son of David? 42 David himself declares in the Book of Psalms: “‘The Lord said to my Lord: “Sit at my right hand 43 until I make your enemies a footstool for your feet.”’ 44 David calls him ‘Lord.’
Paul always warns against debating genealogies:
Titus 3:9 But avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless.
So it would appear there was some divide even among Christians as to whether Jesus was descended from David or not. Those that maintained that he was of the Davidic line don’t appear to believe in the virgin birth.
