One of the first myths of the progress of humanity was created by Joachim de Flore, one of the most important thinkers of the apocalypse and of the history of the medieval period: he conceived 3 ages:
– The age of the father: the people lived under the law of God and served him.
– The age of the son: the people lived under the reign of Christ opening a path to freedom
– The age of the Holy Spirit: humanity is liberated and individualized
Boris Mouravieff also mentions in his Gnosis trilogy the reign of the Spirit; a new cycle for liberated and accomplished humanity, guided by an individual transcendent principle.
