Early Gospels in Circulation: An Even Messier Scenario
When it comes to the early Christian Gospels, most people simply assume that there were four Gospels from the first century (those in the NT), and no others, and that they were written as they are found now, and that they circulated in that form, and that later Gospel writers (say in the second century) who used earlier written sources about Jesus must have borrowed their stories from those Gospels.
