The Pleroma (Greek: πλήρωμα, "fullness") is, in Gnostic thought, the realm of divine light that surrounds and expresses the unknowable God. It is the "Fullness" made up of the Aeons, the eternal powers or attributes that emanate from the Monad. Everything outside it, above all the world we live in, is by contrast a realm of deficiency or emptiness (Kenoma).[1] The drama of Gnostic myth is the story of how a fault arose at the edge of the Pleroma, and of how what was lost from it is gathered back in.
The word
Plērōma comes from plēroō, "to fill". It can mean what fills something, the state of fullness, or completion as opposed to lack. It appears 17 times in the New Testament. The best-known examples are in Colossians: "For it pleased the Father that in him should all fulness dwell" (1:19), and "For in him dwelleth all the fulness of the Godhead bodily" (2:9).[1][2] The Gnostics claimed these passages for their own meaning, and Irenaeus records them doing so.[1] Partly because of these associations, the technical word later dropped out of mainstream Christian theology.[1]
In Sethian texts
In the Apocryphon of John the Pleroma is the whole shining household of the invisible Spirit. It holds Barbelo, his first Thought; the self-generated Christ; the Four Luminaries with their twelve aeons; and the heavenly Adam and Seth. The key word is harmony: each new power "glorified" the Spirit and Barbelo, "for whose sake they had come into being".[3] When Sophia acts alone and falls, the Pleroma answers her as a community: "the whole pleroma heard the prayer of her repentance, and they praised on her behalf the invisible, virginal Spirit." The holy Spirit "poured over her from their whole pleroma". Salvation is finished only "that the whole pleroma may (again) become holy and faultless".[3] The fall is a wound in the Fullness itself, and the redemption of human beings is also the healing of God's own household.
In Valentinian thought
The Valentinians gave the Pleroma its most detailed structure. According to Irenaeus, it contains thirty aeons, arranged in male-female pairs (syzygies). They are grouped into a first Ogdoad of eight (Depth and Silence, Mind and Truth, Word and Life, Man and Church), a Decad of ten, and a Duodecad of twelve. The Valentinians said that the Savior's thirty hidden years before his ministry, and the hours of the parable of the laborers in the vineyard (1 + 3 + 6 + 9 + 11 = 30), secretly pointed to this number.[4] See Aeons for the full list.
A boundary called Horos ("Limit"), also called Stauros ("Cross"), guards the Pleroma. It has two functions. Within the Pleroma it keeps the aeons from being dissolved into the unfathomable Father. At its outer edge it keeps anything foreign from entering.[5] After Sophia's crisis, peace returns: "Everything, then, being thus established, and brought into a state of perfect rest". In gratitude, "the whole Pleroma of the AEons, with one design and desire" pools the finest qualities of each aeon to produce "a being of most perfect beauty, the very star of the Pleroma, and the perfect fruit [of it], namely Jesus". This Savior, "who sprang from all the AEons", will at the end take the fallen Sophia (Achamoth) as his bride, "while the nuptial chamber is the full extent of the Pleroma."[4]
Valentinian texts are careful to say that the Pleroma is not simply a place. In the Gospel of Truth, every emanation of the Father is itself a fullness: "all the emanations of the Father are pleromas". Each soul's own "resting-place is his pleroma".[6] The same text describes salvation as the Pleroma filling what is lacking: "the pleroma, which has no deficiency, but (which) fills up the deficiency".[6] One ancient report, quoted in the Wikipedia article on the Pleroma, says that some held "there is nothing whatever outside of the Pleroma" and spoke of "what is without and what within in reference to knowledge and ignorance, and not with respect to local distance".[1] Irenaeus mocked the other view, that what lies outside the Pleroma has no true existence: "They have thus banished themselves in this world (since they are here outside of the Pleroma) into a place which has no existence."[5]
Philosophical background
The Pleroma resembles Plato's world of Forms and Philo of Alexandria's "intelligible cosmos", the pattern in the divine mind of which the visible world is an imperfect copy. The classicist John M. Dillon argues that the Gnostics drew their idea of the Pleroma from this Platonist tradition.[1] The Valentinian aeons are ideal archetypes. The earthly Church is a copy of the aeon Ecclesia, and the earthly human a copy of the aeon Anthropos. Irenaeus complained that the Valentinians "rehearse the doctrine of Democritus and Plato".[5]
Modern uses
Carl Jung used the word in his Seven Sermons to the Dead, first published anonymously in 1916, for the undifferentiated totality from which all opposites arise. The anthropologist Gregory Bateson borrowed Jung's contrast between pleroma (the undifferentiated world) and creatura (the living world of difference and information).[1] A diagram of the Pleroma reproduced in the Wikipedia article maps the Valentinian aeons onto Theosophical terms such as the "Manasáputras or Sons of Wisdom" and the "Kumâras". It shows how the concept passed into modern esotericism.[1]
In the Alien Archive
The Pleroma is the Gnostic image closest to the Archive's picture of cooperative, luminous intelligences working together in harmony. The ancient texts speak of divine emanations, not extraterrestrials, so these are thematic parallels:
- Galactic Federation: The Archive describes a "coordinated interstellar alliance" with "council-based organization" that maintains "balance between competing cosmic factions". The Valentinian Pleroma is likewise a council of many paired powers who, after a crisis, unite to restore order and produce a common emissary, the Savior.
- Celestials: The Archive's Celestials are "vast intelligences or collective fields of consciousness expressing divine balance" who maintain "light architectures". This is close to the Pleroma as the structured "fullness" of God's attributes.
- Arcturians and Andromedans: The Arcturians serve as "Coordinators / Overseers within larger interstellar cooperative systems", and the Andromedans are "stabilizers within broader interstellar or interdimensional cooperative" systems. The Four Luminaries play a similar role around the self-generated Christ; see Four Luminaries.
- The Pleroma's response to Sophia is to pray for her, not punish her, and to send help that respects her return. This matches the Archive's stress on "non-interference" and on benevolent beings who avoid "overt interference with human free will".
