Please don't repeat a similar Trump's
error.
Bob Price is careful not to be dogmatic about his suggestions that Basilides was behind the Gospel of Mark.
Mark was secretary of Paul according to Papias. But according to Basilides,
Glaukias was secretary of Paul. If Basilides claimed that he knew about the fate of the Cyrenaic from Glaukias, then Mark would have
left Alexander and Rufus (even if he knew that Alexander and Rufus were who informed Glaukias, according to Basilides) in the his effort to supplant the rival (in the his role) tradition who dated back to Glaukias.
A clue in this sense comes from Luke's version of the episode,
paradoxically more similar to the original than Mark's version :
As the soldiers led him away, they seized Simon from Cyrene, who was on his way in from the country, and put the cross on him and made him carry it behind Jesus.
(Luke 23:26)
Compare it with Mark 15:21:
A certain man from Cyrene, Simon, the father of Alexander and Rufus, was passing by on his way in from the country, and they forced him to carry the cross
Note the difference: Mark does
n't make it explicit that the Cyrenaic is going precisely
behind Jesus. Luke
does it explicit that the Cyrenaic goes
behind Jesus. The Luke's version is required by the obvious parallelism with the Jesus's words:
And He summoned the crowd with His disciples, and said to them, "If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me.
(Mark 8:34)
And he said to them all, If any man will come after me, let him deny himself, and take up his cross daily, and follow me.
(Luke 9:23)
My strong suspicion is that Mark broke
deliberately the parallelism required by
ὀπίσω, differently from Luke, who limited himself to remove Alex and Rufus. Or, Luke was based on a version of Mark more old than our Mark, where the parallelism required by
ὀπίσω was made evident as it is now in Luke. The point is that Mark wanted to eclipse the fact that the Cyrenaic was going behind Jesus, because Mark didn't like the fact that the Cyrenaic
succeeded just where Peter failed. Hence this is
not the Mark that we know, the dear old
anti-petrine Mark. This is at contrary a Mark who wanted to
reduce the importance of the Cyrenaic, because he knew the important role played by the Cyrenaic per Glaukias/Basilides.
The Cyrenaic suffered in the place of Jesus, hence he was so much important just as Judas in the
Gospel of Judas.
Jesus said to Judas,
"Step away from the others and I shall tell you the mysteries of the kingdom.
The pattern is repeated: the best disciple is in both the cases who would die in the place of Jesus.
