I was not talking about "literary docs". I was talking about the many gospels throughout scripture.
You have shown yourself to be so consistently wrong that I was using a generalization. A real writer and grammar scholar would understand that.
There is only one gospel when you get to the post-exilic era starting with Isaiah. That is why, as you know as a grammar scholar, it is called the gospel in Lk 4 and Is 61.
When the disciples realized it was going to be about the death of Christ and not a miracle-soaked monarchy in Israel, they blustered. That does not mean what they thought was a gospel was true, nor that any change whatsoever had been made. it means they were immature and in denial.
This is why we are not to take snippets of an unfolding historic account like the gospels-as-literary-docs and say, 'see, there's a different gospel there, than here...'
Watching the disciples mature (which is a big part of the synoptic--Acts taken together) is not saying there are other gospels. Even Paul said he once 'knew' Christ 'kata sarka / in the ordinary way' but now knows... That statement alone means there never was another gospel, just immature and carnal observers.
This is also why we are not to contradict Paul who said there was just one--or be accursed.
