@Foxfyre,
Leaving aside the undeniable fact that we have no historical basis for assuming that scripture as it is known today is the same as what was known in the first century of the common era, your response ignores that the authority for christian teaching derives from a contention that scripture is inerrant, and the divinely inspired word of god. It that were true, there would be no "inevitable contradictions," no variations, no inconsistencies in the text, no errors of any sort.
There is no basis upon which to determine context, intent and meaning in the eyes of first century christians, because there is no reliable record of what they believed about scripture, and no reliable historical basis for inferring what it might have been, or even that the scripture which exists today is the same as what existed then.
Modern scripture is based upon one of several "text types." The most prevalent was once the Byzantine text type, also known as the majority, traditional, ecclesiastical, Syrian or Constantinopolitan text type. The mere fact that there was a "majority" text type implies that there was a minority text type, which was not consonant with the majority text type. The majority text type is found in the most surviving manuscripts, and those manuscripts date from the fourth century or later. Reformation era translations of scripture were based on the Textus Receptus, which was produced by Erasmus in the early 16th century, before the Protestant Reformation. He also produced a new Latin version. He considerably altered the texts with which he worked, in one case saying: "It is only fair that Paul shouldaddress the Romans in somewhat better Latin." He also said: " . . . that often through the translator’s clumsiness or inattention the Greek has been wrongly rendered; often the true and genuine reading has been corrupted by ignorant scribes, which we see happen every day, or altered by scribes who are half-taught and half-asleep." In fact, the first published version was full of typos, and as he did not have available to him complete texts, he sometimes translated the available Latin texts back into Greek, most notably in the case of
Revelations. It's pretty damned silly to attempt to claim anything about what first century christians believed about scripture, and even sillier to contend that scripture is the inerrant, divinely inspired word of god, when the sources for it are so unreliable.
In short, "scripture" as it exists today is not a reliable source either for the divinely inspired word of god, nor for what the earliest christians believed about scripture.
