and Mark 12:12 :He answered them, “The mystery of the kingdom of God has been granted to you. But to those outside everything comes in parables, so that
‘they may look and see but not perceive,
and hear and listen but not understand,
in order that they may not be converted and be forgiven.’”
If the outsiders are condemned to ignorance about the parables, why do they know the esoteric meaning of the Parable of the Workers in the Vineyard ?They were seeking to arrest him, but they feared the crowd, for they realized that he had addressed the parable to them. So they left him and went away.
The problem is so evident that I am inclined to consider Mark 12:1-12 as interpolation.
And if Roger Parvus is right about the absence of John the Baptist in proto-Mark, then the interpolation would be even more large: Mark 11:27-12:12.
The argoment of this kind may be applied in every occurrence where 'Mark' cares explicitly to explain the meaning of verba et acta of Jesus. There is no reason for Mark of explaining the meaning of the parables when the parables are meant to be read correctly only by the insider readers.
