^^Um, exactly. That and the fact that the earliest leaders of the Church after the Apostles (Ignatius, Justin Martyr, Irenaeus, Tertullian, Polycarp, Cyprian) went to very detailed lengths in their expositions of the faith -- often down to the very words or even parts of words in Scripture verses -- to make their points when arguing with Jews or pagans. For them, it was of the utmost importance to be κατα τας γραφας -- according to the Scriptures, not some unfounded oral tradition like the gnostics were doing. Irenaeus went so afar as to say that the κερυγματα, the canon of truth which had been committed orally, was no different than what had been passed down in written form as well, so it was of utmost importance to stay faithful to the written Scriptures...and to do that, you have to engage the text rigorously.
The written Scriptures of the East had somethings that the West didn't write down, and the West had somethings that the East didn't write down, and this is why you will find eastern christians living before as well as a little after 200A.D. quoting Scripture that is a little different (in some places)
from what the western christians were quoting before as well as a little after 200A.D.
Most of it was the same, but there was slight variation, but most if not all of our New Testament Variants existed and were quoted by Christians before the year 300A.D., and that's why I see it all
The latter Byzantine Tradition included both early eastern & western traditions all in one text, and this is why the Byzantine text is usually longer.....for when you read that.....you will be reading everything that both EAST & West had as Scripture.......and thus, nothing will be missing.
Don't forget that the Gospels started out as Oral First, before they were written down, and therefor, it shouldn't matter when "parts"
of the same Oral Tradition was later written, and this is what alot of Protestants, as well as Liberal Protestants, just don't understand. They know that the Gospels were Oral first, but they reason as if, they were written first. In doing so, they ignore the real impact of Oral Tradition, and the Cultures who relied on Oral tradition more than written Tradition.
Therefore, we should start with the Premise of Oral Tradition, and then go from there.
