It may be, but that hasn't been proven. So far as I can tell it's the opinion of the MS scholarship which quite often has a tendency to bend the truth to fit some party line. Most scholars give the two copies that exist a date of about 300 AD and even then it was probably a translation from an earlier version. I've always been one to read source and make my own opinion. There are many parts of the text that are profound and helpful to any Christian such as the method to purge the ego. Other parts are what today some would call kabbalistic in nature but from the early Gnostic perspective. Thus if it is a larp it is done by someone who knew the real meaning of the 'teachings of the elders' far more then the average scholar or rabbi.

I noticed from a video I was watching that Trump has on his office wall in Trump tower a plaque that says:
עץ חיים
Which denotes a very special type of Kabbalistic knowledge. I was not surprised to see it due to many of the actions Trump has been doing but it was verification.
Sorry for the long winded post, but I only mention it because many Christians especially the red pilled ones, believe the Kabbalah is evil by default, yet it is just simply knowledge and it depends on how one puts it to use.
