Many possible responses here. The Canon of Scripture is closed. I’ve heard that unapproved manuscripts WERE destroyed, as much as could be determined, but maybe not this one.
Saw a show about the gospel of Mary Magdalene – about 3 inches by 4 inches. a fragment that asserts that she and Jesus were married.
If Jesus had been married, I don’t think there would be any reason to hide it. This subject, however, trails off to that of the “bloodline of Jesus Christ.”
Recall that St. Paul says that if anyone, even an angel, were to bring a ‘gospel’ different from his teaching, it was to be rejected.
In the Jewish Study Bible (Oxford U), there is an essay about the dead sea scrolls that demonstrates that there were preserved three full variants of Jewish / Hebrew writings. Only as an observation from a non-qualified person: The Septuagint holds the scriptures which the Jews themselves considered important to translate into Greek and to distribute to Jews in the Diaspora who no longer could read the scriptures in the original language. That sort of nails down the scope of possible texts for canonization (although not all of the Septuagint was accepted by the Catholic Church). The Orthodox Churches preserve the Septuagint but they have not issued a statement on canonicity. For a long time, they did not read from the book of Revelation, although it seems to have gained later acceptance. The OC relies heavily on tradition and so they just pass on what they received.
