- The Bible came later, much later, and was determined by the Church? The Bible was Canonized much later… But the Church always had the apostles writings and viewed them as scripture. It’s not like all of a sudden in 400 AD the bible flew from the sky and was “discovered”.
Alright, I need to clear this up.
The first generation of Christianity was a Jewish movement, in one sense just another form of Jewish diversity (Second Temple Judaism was highly diverse that some scholars even prefer to use the term ‘Judaisms’, considering each and every group a ‘Judaism’ in its own right): in its externals it would not have looked much different from other Diaspora Jewish communities. For one, the Apostles themselves still worshiped in the Temple and identified themselves as Jews (St. Paul himself, while he is credited with starting the chain which led to the eventual official divorcing of Christianity from Judaism, was keen to assert his Jewish identity when pressed). Believing in Jesus as the Messiah did not mean converting from one faith to another, i.e. rejecting Judaism in favor of something else: rather, this belief is seen to complete and fulfill the lives they have within Judaism. One can say that the first members of the Jesus movement or “
the Way” saw themselves as ‘perfected’, ‘true’ Jews. Hence, when the word ‘Scripture’ is used by them, it meant what it means in Judaism: the books of the Old Testament.
As in Jewish synagogues, scrolls of OT books would have formed the core of collections of Scripture in local Christian churches: the Torah, some Prophets, a few Writings, or perhaps even a collection of quotes and snippets from various OT books sharing (or being perceived to share) a similar theme, known as a
testimonia. Given how expensive scrolls were in those days, most Jewish and Christian communities would not have had
all the Scriptural books within access but would have just had the more popular and frequently-used ones like the Torah, the Psalms or Isaiah handy. Indeed, the idea of having each and every Scriptural book under one cover (as our modern Bibles are) is a later development which came hand-in-hand with the closing of the canon: it was after the canon of Scripture was fixed that we begin to see the prototypes of our Bibles circulating.
Eventually this collection would have been supplemented by early Christian texts that were gaining importance and authority as interpretations of the church’s faith in the light of Jewish Scripture. They would have likely had copies of letters attributed to authoritative figures like Paul or Peter or even Clement or Barnabas or Ignatius of Antioch, or again, another handy collections of ‘excerpts’ from such epistles. They might have apocalyptic texts, like that of John (which is canonical) or of Peter (which is not) or of any other NT figure, or none at all. They would have had one gospel or two, attributed to authors like Matthew, Mark, Luke, John, Thomas, Peter, James, Mary or, again, whatever heavyweight Christian figure one could name. Some might even prefer a harmonization of different gospels (like Tatian’s
Diatessaron). Then there is also the matter of language: by the 2nd and 3rd century churches in the western half of the Empire preferred Latin translations, while those in the East used different languages like Greek, Syriac, or Coptic.
In short, different Christian communities would not have even agreed on which books to own and read (by ‘reading’ we do not mean “picking a book from the shelf and reading quietly,” but “picking a book from the shelf and reading it aloud in public before everyone”): it all depended on practical matters, such as what texts in what languages were available for copying or which texts get to be read more often in this particular community, as well as the theological orientations of the churches in question (be it orthodox, gnostic, Docetic, Adoptionist, Judaizer, or any other ‘form’ of Christianity from all sides of the spectrum one could name) and their particular needs (which Scriptures best spoke to the interests and practices of which communities?) Given how in one sense, there was a huge diversity of ‘Christianities’ before the Church’s teaching was defined in the great councils (under the traditional way to put it: there were a lot of heresies coexisting with orthodoxy), it is no surprise that there would also be a huge variety in the form of Scripture - which was also the case with the Judaism/s of the Second Temple period.
