Interesting points from Mark Goodacre:

• Primitive source versus elaborate, eloquent composition in Luke;
• Skepticism about the ability of scholars to reconstruct sources;
• Definition of Occam’s razor;
• The entire Greek-Roman literary context influences Mark;
• Take Papias seriously;
• Historians are all, in a sense, frustrated archaeologists;
• One of the most fundamental issues is that Luke knew Matthew;

Interesting points from Dennis MacDonald:

• How in terms of technology, Luke and Matthew used their sources;
• Is literary creativity on the part of Luke sufficient to explain the deviations from Matthew?
• As long as the methodology to compare the gospels is right, there is no need to worry about Luke and Matthew
