Yeah that for me crosses a line; whereas the synoptic Gospels do add their own personal prophetic interpretation; which is understandable, we all do that...John moves it further back to pre existence.
John 1:1 puts forward ideas that are the authors, about the creation of reality... So we have some anonymous author creating theology; rather than it being from someone who we know is from the Divine.
Luke 20:19-20 The chief priests and the scribes sought to lay hands on him that very hour, but they feared the people—for they knew he had spoken this parable against them. (20) They watched him, and sent out spies, who pretended to be righteous, that they might trap him in something he said, so as to deliver him up to the power and authority of the governor.Matthew writes with the insight of post resurrection faith.
Mark 12:12-13 They tried to seize him, but they feared the multitude; for they perceived that he spoke the parable against them. They left him, and went away. (13) They sent some of the Pharisees and the Herodians to him, that they might trap him with words.
Both other Gospels have it as something that happened after the Parable of the Wicked Husbandmen (the Tenant Farmers).
In my opinion.
