Content Analysis: Mark's Unique Contributions
Material Omitted by Matthew and Luke
Mark's brevity is notable. Key elements absent from Mark include detailed infancy narratives (found in Matthew and Luke) and the Lord's Prayer (present in both). Marcan priority suggests these omissions reflect Mark's specific editorial focus, possibly prioritizing eyewitness testimony from Peter or aiming for a concise kerygmatic message. The absence of such significant material poses a challenge for theories suggesting Mark wrote last.
Unique Passages in Mark
While most of Mark's content is paralleled in Matthew or Luke, a few passages appear uniquely in Mark. These include the Parable of the Growing Seed, the healing of the deaf mute of the Decapolis, the healing of the blind man of Bethsaida, and the incident of the naked fugitive. The presence of these unique, sometimes obscure, passages is seen by Marcan priority proponents as difficult to explain if Mark were merely compiling from Matthew and Luke, but more plausible if Mark were drawing from an independent source.
Narrative Details
Beyond distinct pericopae, Mark often includes specific details absent in the parallels, such as the location of Jesus sleeping on a cushion during the storm or the use of saliva in healing. Marcan priority views these as Mark's characteristic narrative embellishments or details preserved from his source (traditionally Peter). Marcan posteriority must explain these details as Mark's unique additions, potentially to enhance vividness or contrast.
