There is nothing interesting about this. Gnosticsm is not new to Christianity. It flourished well in the second century giving rise to many spurious gospels like the gospel of Peter, Philip, mary magdalene etc. All of these are fakes and their authenticity can never be proved and they cannot be trusted for any valuable historical information. Contrary to this the four Biblical gospels were written in the first century just with in a few years/decades after Christ. They have more reliable historical information compared to all the others.
