Licona's book Why Are There Differences in the Gospels? required classicist review to avoid errors in Plutarch material — illustrating disciplinary boundaries

When Licona wrote Why Are There Differences in the Gospels? (published ~2017), he dealt extensively with Plutarch. Three classicists reviewed his Plutarch material and one in particular corrected him extensively — preventing what would have been "egregious errors." This illustrates that New Testament scholars and classicists have distinct competencies.
