Matthew does not mention Judas leaving at all.
Mark does not mention Judas leaving at all.
Luke does not mention Judas leaving at all, and in fact states that he was there AFTER the passing of the emblems.
John DOES mention Judas leaving early, but does not say when it took place in relation to the passing of the emblems.
Also it's worth mentioning that, according to JW dates, John was written a good 30 years after the other 3 gospels were completed.
So until then, nobody would have even known that Judas left at all. Let alone before the meal.
Also the word used for 'logical'. If it's not Chronological then what the heck is it? How is it more logical to put Judas at the table after the passing of the emblems if it's important that he was NOT there?
Looking at other translations it sure seems like he's talking about putting them in order based on TIME, not some other unspecified definition of 'logical'. The greek word used was: Kathexes seems to be talking about chronological order to me, if not, I'm honestly pretty confused about what he could have meant.
