We still have people like Bauckham talking about how it's inconceivable that the writer of Luke would have used the letters of Paul, and thus similarities between Luke and Paul can "only" be explained as evidence of "lost original sources". I mean seriously, Bauckham is a highly respected biblical scholar. How can this be. When your most respected scholars say obvious nonsense like this and they are treated as legitimate authorities what else can be said. The whole field is just nonsense.
