Here's a link to a fast-paced 40-minute interview -- Steve Noble interviewing my friend Mike Licona -- on gospel differences. Mike is an expert on the character of ancient biography. Ancient Greco-Roman biographies are called bioi, or vitae. As Dr. Licona makes clear, bios as a literary genre is more flexible than we might realize. And yet this is the genre of the gospels.
This isn't to say that there are gospel errors. Any "mistakes" are ours. Our preconceptions as we approach the biblical text can lead us to discover problems where there are none.

To refresh your knowledge or if you want even more material (48 minutes), here's a great class by Licona on gospel differences.
