Ficino and Giovanni Pico della Mirandola endeavored to reform the teachings of the Catholic Church by means of the writings of the prisca theologia, which they believed was reflected in Neoplatonism, Hermeticism, and the Chaldean Oracles, among other sources.
[3] ...[Ficino] saw himself as one member of a venerable sequence of interpreters who added to a store of wisdom that God allowed progressively to unfold.
[4] Enlightenment thought, like prisca theologia, tended to view all religion as cultural variations on a common theme,[5] but it tended to denigrate prisca theologia along with the rest of revealed religion.
[6] Prisca theologia is related to concept of perennial philosophy, but an essential difference is that prisca theologia is understood to have existed in pure form only in ancient times and has since undergone continuous decline and dilution;[citation needed] but perennial philosophy asserts that the "true religion" periodically manifests itself in different times, places, and forms, potentially even in modern times.
Both concepts, however, do suppose a unique true religion and tend to agree on its basic characteristics.
