Yes...and no.
Valentinian Aeonology i s rooted in early Christian thought. Valentinus himself was a 2nd Century Christian teacher who drew deeply from scripture, spiritual experience and Greek philosophical traditions. His followers at that time, viewed his teachings as a deeper more mystical interpretation of Christ's message — a kind of esoteric Christianity that focused on inner light, inner transformation and direct encounter with the divine. In that sense, Aeonology is a Christian, mystical system that aligns with the many its ideas divinity, cosmology and salvation. Almost all of the Aeons are mentioned somewhere in the either the old or the new testament — Word, Truth, Light, Church, Love.
On the other hand, because Valentinus and other Gnostics beleived in divine knowledge (gnosis) that was revealed inwardly— not solely through the authority of the church— this view was labelled 'heresy' by the institutional church. When the biblical canon was formalized in the 4th Century, many texts, including the teachings of Valentinus and Aeonology, were suppressed.

Today some Christian denominations still consider Gnostic teachings to be heretical. Others, especially Gnostic denominations and scholars see it as a valid branch of Christian thought — some going as far as believing it is a purer source of Christian teaching because it escaped corruptions of religious orthodoxy and dogma by being buried in the Egyptian desert for several centuries.
