Established councils is what established God's Word. Or do you consider Apocrypha to also be God's word? Where do you think the Bible came from?
I think it is more in-depth.
* However in Brief, Men did not Establish Gods Word, Gods Word is eternal.
OT was already written, copied, distributed, sometimes destroyed, rewritten from memory by men Faithful to God, ie OT Prophets, and Tribal leaders.
* The NT ... What Jesus spoke, what Jesus taught his disciples for 3 years daily, were,
(Excluding some of the Letters personally written by some of the Apostles)...
* The Scriptures were written BY SCRIBES (a sort of ancient Secretary).
* The Scribes writings, were Transcribed BY
RECORDERS, written ON SCROLLS.
* The SCROLLS, were not in one neat handy location, since there was; NO TEMPLE in Jerusalem, and fear of confiscation; the Scrolls were in different Synagogs and Hidden places.
* And Scribes and Recorders of the Scriptures, were not the Only people who could write...Kings themselves had troops of Scribes.
* As far as "Councils"... there was no "established" yearly council perse'.
Councils met at differing times, for particular purposes; For example, deciding to have a POPE, deciding Priests could not marry, deciding Only a Priest could baptise a person, etc.
And yes, they fairly well agreed the very NT early teaching was by word of mouth and gradually ..."books/scrolls" ... were assembled...that early teachers agreed were authentic...and being taught in early Churches....and some writings not particularly forgeries, but not assured were the Lords or Apostles.
* I believe it was Constantine who proposed one of the very early Councils...for the express purpose of Combining into a book form the different available and verifiable scrolls/ writings.
Not saying Constantine had anything to do with what would be considered accurate to include.
* I am confidant the men who worked diligently on assembling the book we call the Holy Bible, did so with much prayer and discussion and caution.
* I Trust God, being capable of Guiding mens hearts, minds and hands, to accomplish His will.
* As far as the Apocrypha; seemingly they are Transcriptions BY Greeks, as to their understanding, of some OT Hebrew writings;
(Which Jews do not accept, and Many Christians find as unproved and not authentic.)
Mark 13: [
31] Heaven and earth shall pass away: but my words
shall not pass away.
