The Tracy Marx Show - Was Jesus Really Born of a Virgin?

In this Christmas episode we find that Matthew 1:18ff tells us that Mary was a virgin when Jesus was conceived in her.  Can that really be true?  Or has Christendom been spreading fairy tales for 2,000 years?  Dr. Marx addresses the virgin birth of Jesus and how some, including Bishop John Shelby Spong, have reduced it to nothing more than a myth.
