We insist that this Atonist doctrine was a key pylon in the foundation of both Judaism and Christianity. Although the earliest "Christian" sects sought to live humble spirit-focused lives as taught by their savior, and although they honored the apostolic tradition of poverty, the leviathan of the later Roman Church took a suggestively different course. The shameless decadence and arch-materialism of the Vatican stands out as further proof for their Atonist origins. The abandonment of all gods but one, the adoption of a theology of light, the denial of Underworld rituals and tradition, the lionization of an exceptional but short-lived leader, the heinous cruelty against adversaries, and chronic unbounded materialism, are the commonalities between Judaism, Catholicism, and Atonism. They are the hallmarks of all three.
