There was the great schism between the Orthodox Christian church and the Catholic Church in 1054. When I look at it through a Buddhist lens, the Catholic Church has been turned over to the Archons (ἄρχοντες), the supposed rulers/wardens of our samsaric sim-world from which there is little, if any, escape. If we look at the Gospel according to Mary Magdalene, composed as a post-resurrection gospel, it sheds light on something Christians have not given much attention to, which is significant to the faith and its survival.
In a nutshell, those who have just died must face the Seven Wrathful Powers constituted by the Archons who lead the faithful to perdition, preventing a jailbreak. They have entered what Buddhists know as the Bardo, or in Sanskrit, antara. In other words, a person just doesn't die and go to heaven; they die and are judged by their errors, which they succumbed to because of the power of the Archons. They have been deceived, but not just externally, but from deep within, by the very religious attitude which they believe is Christian, but which is a path of the Archons. The Christian has lost sight of the theme that salvation is a process of inner transformation — a liberation from the grip of these powers before death. Even those people who have had near-death experiences (NDEs), having been in the Bardo, who return to the sim-world of the archons, have only just begun a journey of inner transformation which is far from complete.
Mary Magdalene’s Gospel depicts a Bardo-like journey through an in-between state that must be faced. The Seven Powers of Wrath are: 1) primordial nescience, the “blind spot” that hides origin; 2) craving; 3) mis-knowing that reifies appearances; 4) acquiescence to impermanence; 5) identification with the condition of embodiment; 6) rationalizations that justify clinging; 7) the self-righteous will to dominate. These powers are well within each individual, especially in today's complex world.
Buddhism, it could be argued, because it is older than Christianity, is more advanced. There is enough to warrant that the religious practitioner in both religions is not going to be saved by some God or some super cosmological force. Even the belief that after death one just goes to oblivion at death has no heft in Buddhism or Christianity. The root fact is that both religions see the human being as a person in ignorance of their divine nature. Each person has the choice to either make a jailbreak from Samsara and the archons or become continuously reborn into a sim-world that is literally going around in circles. Oblivion is not an option.
