He is attempting to demonstrate that the Christ mentioned in the NT, is not who and what the prophets were speaking about
Quite so: just as you might try to demonstrate that the chair you saw on Saturday was not the grufflepuff that I was speaking about.
This is easy to do. You would observe that it did not have purple wings nor play the trombone. Then you'd know that my prophecy did not apply to your chair.
At no point would you have to assume that I was in any way correct or accurate.
By direct implication or outright assertion he is assuming the prophets were correct or accurate in their statements, of and about the the things the prophecied
No, of course he isn't. Don't be silly.
Now if he is saying as you have indicated that they are not accurate, it would follow logically, he has no way of knowing whether Christ was not the fulfillment
Of course he can; just as you can say that I am not accurate and still know that nothing you saw on Saturday was the fulfillment of my prophecy about the grufflepuff.
Indeed, the two go hand in hand. You cannot point out that my prophecy was not fulfilled without also believing that I was inaccurate in making the prophecy.
Or at least a rational person couldn't. I do not wish to set arbitrary limits on
your capacity for doublethink.
