Or they just picked the ones they liked the most. I in fact listed the Bible as one of the Catholic inventions, because I don't believe it. But just because something ends up in it doesn't mean it's invalidated either, because it was originally separate. And all the writings are spurious, there are undeniably a metric fuck ton of edits and interpolations everywhere, especially in Paul's letters (which is why he talks in word salads and contradicts himself at every turn), and we don't know who the authors of any of the gospels are. John is no more likely to be written by John than Thomas is to have been written by Thomas. Actually Thomas is probably more likely, or at least part of it, because it's in such a primitive form (simply a list of quotes). I don't care about Enoch except what it can reveal about Jewish beliefs at the time, and in my example it shows that they thought גדר האל was a name for Satan.
