Gurdjieff's ideas, like those of the Bible itself, are clearly mythic: they attempt to speak metaphorically of truths that do not lend themselves to ordinary language or thought. As for humanity serving as food for the moon or the moon turning to blood, the old esoteric maxim holds good: "Neither accept nor reject." There is an attitude of mind whereby one can entertain and contemplate ideas like these dispassionately and openmindedly without falling into the traps either of credulity or reactive skepticism. This is not an evasion or an attempt to deflect legitimate criticism: rather, it is meant to cultivate a certain freedom of thought that can go beyond the boundaries of dualistic yesses and nos.
Finally, there is John, the Gospel that is different. It does not talk about Jesus' birth, it does not show him speaking in parables, and it says little about his preaching in Galilee, which probably occupied the greatest part of his public career. The Gospel of John takes place mostly in Jerusalem, and this detail, while apparently inconsistent with the synoptics, offers an important key to what John is trying to accomplish. His Gospel does not speak to the three lowers aspects of our natures, as the others do; it address the highest part, the spirit, or "I", which unites and harmonizes these three; it rises above them, which is why it is symbolized by the eagle. In the Bible this part of the human makeup is symbolized by Zion or Jerusalem, the seat of the Temple, where Israel makes contact with the presence of the living God. John does not show Jesus speaking in parables because at this level analogies and stories are unnecessary and possibly unhelpful; what is disclosed in encrypted form by the synoptics is uttered openly here.
There may be some value, then, in approaching the Gospels not as if they were newspaper articles giving contradictory accounts, but as sacred texts presenting the same truths in a manner that speaks to different types of individuals as well as to different levels of our own being. Such a perspective may help us to step beyod the apparent discrepancies that have dogged so many readers of these texts. If we can open the manifold aspects of our natures to the Gospels, they can disclose themselves to us in our fragmented state and help to integrate it.
