this may or may not help,,,,it was something i found back when i was trying to research/study the dates of these writings(but rev. of john was the issue then),,,,but pauls books then come into play as to the dating of any of the books.
https://en.wikipedia.org/wiki/On_the_Detection_and_Overthrow_of_the_So-Called_Gnosis#Main_arguments this is from the text of irenaeus a.h. book 2 chapter 22,,,now from looking close at the wording of irenaeus he states the jews said "not yet 50",,,,but if he was not over 40 then they wouldnt have argued with him(christ)at all becouse he was still too young to teach. so 45-ish?,,,,,may explain the theory to 9bc???
also,,from the early church fathers,,,
https://en.wikipedia.org/wiki/On_the_Detection_and_Overthrow_of_the_So-Called_Gnosis#Main_arguments ,,,,,,,,these are sporadic writings from Ignatius,,,down at the bottom in his letter to his daughter(mary),,,he states his whereabouts(as to time),,,we can calculate his death by it. and also he writes two letters to "john the apostle",,,and two to mary(see text of letter's) but there is only one we have.
he states many things "important to dating" in these letters,,,,i.e. ,,,"i would go to Jerusalem"(so before July a.d.70),,,,,in another he states "peter was crucified,,,James and paul beheaded ect.),,so they were already dead at the time of his writing. now he wants to see "James the brother of jesus becouse he looked as if he were his twin",,,,so at the point of time he wrote this "james was living",,,,which James?,,,
now Ignatius died 108ad?,,2571 old dating????(correct my recollection,old memory),,,but in any event his letters to the churches and his sporadic letters that is,,,,if Jerusalem was by this time already "besieged",,,,why would he go there to visit Mary and john james ect.?????,,,so its at least before the moat was dug around Jerusalem.
now after that the Christians went north during the Jewish uprising,,,,,so if he(Ignatius) is stating mary,james,john ect. was still there and he(Ignatius) was thinking about going there,,,,,it was around ad67-ish,,,,before the Romans besieged the city.
ken,this is why i was looking at the wording of "stater coin" when we were discussing the copper scrolls,,,,"i was trying to afix a dating standard",,,,,,,were they Greek stater's? or were they the coins the jews minted and put into circulation in the revolt????hmmmm,,,unless we find them we may not know,if they are Jewish coins(copper scrolls),,then they also moved manuscripts to Qumran(just a theroy),,,,,
i will just sit and watch now,,,,my interest was to the book of Revelations,,,,ad96????why speak of a city laid in waist as if it were still standing???,,,,,,,,,
several times i notice ken say "the scriptures they were referring to",,,,and i always think "yes,preach on",,,,,,,,,,,but this is a very difficult thing to explain on the www. ,,,,,,,,,that is we see "rightly divide the word of truth,as written in the scripture of truth,,ect.ect.",,,,,,,,,,,,but,pretend in your mind,,you are alive in the year ad54,,,,"the dating of the new testament books",,,,
now bear in mind the first church was converted,,,before the book of Luke was written,,or revalations,,,or 2nd peter,,,or Galatians,,,,ect.,,,,so if someone believes Paul was referring to his own letters as he was preaching "they had not been written yet,or was in the process of being written",,,,,,,,,,,so peter,paul,james,,ect. were always refering to the "books",,,,that were already written when they were born,,,and the Gospels and the epistles they were writing were to explain to the many who will come to rightly divide the scripture preceding them.
although we are free from the law,,,,the scripture confesses the freedom from it,,and all then are bound to the freedom,,,,,,,but this should be another thread,,,,,but i see you saying it,,,and correctly,,,,but not here my friend in another thread,,,,,,
