New Testament scholar R.T. France observes, “At the level of their literary and historical character we have good reasons to treat the Gospels seriously as a source of information on the life and teaching of Jesus, and thus on the historical origins of Christianity….Beyond that point, the decision as to how far a scholar is willing to accept the record they offer is likely to be influenced more by his openness to a supernaturalist world-view than by strictly historical considerations.”
The real question is whether someone is going to reject miracles a priori or whether they will be open to actually examining the evidence on a case by case basis.
