The Religion Guy observes that the wording of the perennial question above is the title of an important new book by Michael Licona of Houston Baptist University and published by the prestigious Oxford University Press.

Variations among the four New Testament Gospels in parallel accounts of the same events and sayings are fascinating for scholars. And they can perplex believers, though most involve details that don’t affect the main teaching or are easily explained in Bible commentaries.

Meanwhile, those who seek to deride the scriptures and thus the Christian tradition emphasize these differences, calling them “contradictions” and “mistakes.”

In reality, there are fewer such puzzlers than skeptics imply, yet more of them than many believers might admit.

Licona’s research on this is deemed “significant” by Dale Allison of Princeton Theological Seminary, “illuminating” by Richard Bauckham of the University of St. Andrews, and “exemplary” by Christopher Pelling of Oxford University.

In his scenario, the Gospel writers or editors followed a flexible process that was commonplace in ancient times but doesn’t always fit present-day historiography (history-writing): “Ancient biographical conventions provided authors a license to depart from the degree of precision in reporting that many of us moderns prefer.”
