The leading New Testament scholar from Cambridge, Dr. Richard Bauckham, was recently on the radio program 'Unbelievable?' which is on the Premier Christian Radio network. Bauckham was arguing that the Gospels are based on eyewitness accounts and therefore should be regarded as fundamentally trustworthy.
Joining in on the discussion was also New Testament historian, Dr. James Crossley, discussing the implications of Bauckham's work and whether the Gospel of John was written by the disciple John himself, as Bauckham claims.
It is well worth the listen.
