Gnosticism
religious movement
Main
any of various related philosophical and religious movements prominent
in the Greco-Roman world in the early Christian era, particularly the
2nd century.
The designation gnosticism is a term of modern scholarship. It was
first used by the English poet and philosopher of religion Henry More
(1614–87), who applied it to the religious groups referred to in ancient
sources as gnostikoi (Greek: those who have gnosis, or “knowledge”). The
Greek adjective gnostikos (“leading to knowledge” or “pertaining to
knowledge”) was first used by Plato to describe the cognitive or
intellectual dimension of learning, as opposed to the practical. By the
2nd century ad, however, gnostikoi had been adopted by various Christian
groups, some of which used it positively as a self-designation, though
others criticized this practice as a presumptuous claim of exclusive
access to truth.
Definition
Consensus on a definition of gnosticism has proved difficult. The groups
conventionally classified as gnostic did not constitute a single
movement with relatively homogeneous organization, teachings, and
rituals. Even the self-designation gnostic is problematic, since it is
attested for only some of the traditions conventionally treated as
gnostic and its connotations are ambiguous. Whereas some researchers
argue that the term gnostic should be restricted to the sects or schools
that called themselves by this name, others extend the category to
include additional religious movements that allegedly shared various
distinctive features. Still others treat gnosticism as a world religion
that existed from antiquity to early modern times—surviving, for
example, in the mythology and ritual of the Mandaeans of Iraq and Iran
(see below Influence).
Many of the so-called gnostic groups are characterized by a mythology
that distinguishes between an inferior creator of the world (a demiurge)
and a more transcendent god or order of being. Another frequently
encountered theme is that there is a special class or race of humans
that is descended from the transcendent realm and is destined to achieve
salvation and to return to its spiritual origins. Salvation is
understood as a revelation that reawakens knowledge (gnosis) of the
race’s divine identity; in contrast, the more “orthodox” Christian
emphasis is on redemption through the death and resurrection of Jesus
Christ. Although the myth of a demiurge and the theme of reawakened
awareness of divine origins have parallels in Platonic and
Neo-Pythagorean philosophy—and in fact were partly derived from those
traditions—it is often asserted that in the gnostic myths there is a far
sharper dualism, involving a much more negative attitude toward the
inferior creator god, the material cosmos, and the human body.
Texts » Adversus haereses
The classic source for ancient controversies regarding groups
conventionally classified as gnostic is Adversus haereses (Latin:
“Against Heresies”), a five-volume work written in Greek about ad 180 by
the Christian bishop Irenaeus of Lyons. Originally titled “Exposure and
Refutation of Knowledge Falsely So-Called,” this extraordinarily
influential work was studied, adapted, and expanded upon from the late
2nd through the 4th century by Christian writers including Clement of
Alexandria, Tertullian, Hippolytus of Rome, Origen of Alexandria, and
Epiphanius of Constantia. In Adversus haereses Irenaeus catalogs and
criticizes the doctrines of various Christian teachers and their
followers from the 1st and 2nd centuries, devoting particular attention
to Valentinus and other teachers who were said to have adapted
Valentinus’s doctrines. He also reports on the teachings of other
deviant movements, such as those of Simon Magus, Menander, Satornil (or
Saturninus) of Antioch, Basilides, Carpocrates, Marcellina, Cerinthus,
Cerdo, Marcion of Sinope, Tatian, and the Ebionites.
At one point Irenaeus mentions “the sect called gnostikê,” or
“knowledge-supplying,” whose myths he claims had been adapted by
Valentinus. He may have had in mind the teaching that he later
summarizes as that of certain gnostikoi—or “Barbelo-gnostikoi,” as the
original text may have read. The summary of the myth is ambiguous at
points, but it begins with a primordial aeon (eternal entity or age)
named Barbelo and an unnameable Father, perhaps to be understood as
female and male aspects, respectively, of the highest god. In any event,
the Father and Barbelo generate a divine family of entities, each of
which is a mythic personification of a divine faculty or attribute:
Thought (a personification of the Father’s first self-thought),
Foreknowledge, Incorruptibility, Eternal Life, and so forth. Among these
spiritual entities is a perfect human named Adamas—a divine prototype of
the earthly Adam of Genesis. Adamas is united with a consort, Perfect
Knowledge (gnosis). This teaching thus provides a mythic account of how
plurality (of divine attributes) originated from unity and how true
humanity is also divine. The last divine entity to emerge is Wisdom. But
unlike the other entities, Wisdom is said to be without a consort. Her
attempt to find one, though well intentioned, leads her away from the
supernal realm to lower regions, and she generates an inferior “first
ruler” who then creates the material world.
The myth conveys the message that the biblical creator is only a
parody of divinity. Life in this imperfect world does contain inklings
of truth; human wisdom does have a relation to divinity reality. Yet
wisdom can go astray, and false gods can result. Humanity, in a state of
spiritual amnesia before accepting the revelation of this myth, is
awakened by reconnection with Perfect Knowledge.
Many scholars would reserve the term gnostic in the most proper sense
to the sectarians who taught this myth. Irenaeus’s use of gnostikoi is
somewhat confusing, however, since he sometimes seems to apply it to all
of the groups he condemns, rather than to only one or two sects—as when
he refers to “Marcion or Valentinus or Basilides or Carpocrates or Simon
or the rest of the falsely called ‘gnostics.’ ” Furthermore, it is
uncertain from his report how many of these movements called themselves
gnostic and whether those that did intended the term as a proper name
indicating sectarian identity or merely as the assertion of a general
quality (“informed” or “enlightened”). Later sources provide further
information about the movements described by Irenaeus as well as about
other groups, but they offer little help in understanding the term
gnostikoi itself, which they sometimes apply to one or two specific
sects and sometimes to a wide variety of groups deemed heretical.

Texts » Apocryphon of John
Until the 20th century the works of Irenaeus and other heresiologists
(orthodox Christian writers who described unorthodox groups) were the
principal sources of information about gnostic movements. Only a handful
of manuscripts containing the authentic writings of such groups were
known; they existed primarily in two sets of Coptic texts, the Askew
Codex and the Bruce Codex, which were discovered in Egypt in the 18th
century but not published until the 19th century. A third important
Coptic text, known as the Berlin Codex 8502, was announced in 1896 but
not published until the mid-20th century. In 1945, 12 additional codices
and parts of a 13th codex, all probably dating from the 4th century,
were discovered near the town of Nag Hammadi (now Naj Hammadi) in Egypt.
The Nag Hammadi collection contains Coptic translations of more than
four dozen writings that are diverse in type and content, including
“secret sayings” of Jesus, non-Christian works belonging to the Egyptian
Hermetic tradition, theological treatises, and lengthy mythological
stories. Many of the works also contain doctrines or myths that were
condemned by Irenaeus and other heresiologists.
Among the Nag Hammadi writings are three separate copies of the
Apocryphon of John, an especially important gnostic myth; a fourth copy
is included in the Berlin Codex 8502. Corresponding closely to the myth
that Irenaeus ascribed to the sect called gnostikê, the Apocryphon
purports to be a secret revelation from Jesus that was received in a
vision by the apostle John. It conveys the true nature of the divine
realm and its relationship to the material cosmos and humanity. While
the transcendent god or invisible spirit is inconceivable and ineffable,
the pleroma (Greek: “full perfection”) of the divine is a hierarchical
family of personified aeons, who emerge as the fruit of the spirit’s
self-contemplation or self-expression. For example, as in the myth
described by Irenaeus, Barbelo emerges as the first thought of the
transcendent god, and she is soon accompanied by Foreknowledge,
Incorruptibility, Eternal Life, and others. The imperfect material realm
is understood as a copy of the perfect spiritual realm, an idea partly
derived from the Platonic doctrine of Ideas, or Forms. The myth also
draws on the biblical theme of humanity as formed in the image of God
(Genesis 1:26–27); true or divine humanity, however, is this spiritual
family brought into being in the realm of perfection as the spirit’s
image. This realm is the dwelling place of the spiritual Adamas, his son
Seth, and the race or offspring of Seth.
The creator of the visible realm and of the earthly Adam and Eve of
the biblical Garden of Eden is a lesser being, a ruler (archon) named
Ialdabaoth, who is a dark caricature of the creator God of Genesis and
the demiurge of Platonism. Wisdom, the lowest entity in the realm of
perfection, creates Ialdabaoth in an unauthorized attempt to produce a
likeness of herself. Ialdabaoth in turn creates the material cosmos and
rules it with subordinate powers who are his own imperfect offspring. A
willful and malevolent figure, Ialdabaoth is unaware of any power above
him and is easily duped by providence into actions that either serve
divine ends or are stymied by countermeasures from the divine realm. He
does not realize that his cosmos is patterned after a more transcendent
realm, and he ignorantly boasts that there is no god above him.
When, in response to this declaration, the image of the divine
humanity above is revealed on the waters below—an allusion to Genesis
1:2 (“the earth was a formless void and darkness covered the face of the
deep, while a wind from God swept over the face of the waters”)—Ialdabaoth
and his rulers fashion an Adam in its likeness. Wisdom then tricks
Ialdabaoth into breathing life into this figure, an act that empties him
of what power he had received from Wisdom and transfers it to Adam. The
spiritual power now within Adam is portrayed as a feminine entity who
supplies him with insight that makes him disobedient to Ialdabaoth. The
latter then attempts to deprive Adam of this power by putting him to
sleep, extracting the power from Adam’s rib, and molding it into the
shape of a woman. But Ialdabaoth’s plan fails. For in this revision of
the biblical myth (Genesis 2:21–23), when Adam awakens and beholds the
woman, Eve, he experiences an even deeper insight, an awakening from the
“drunkenness of darkness.” Enraged, Ialdabaoth casts the couple from
paradise, introduces sexual desire, and seduces Eve and begets from her
Cain and Abel. Because their father is an oppressive archon rather than
a human, however, Cain and Abel are the same. As archons, they rule over
the material elements (fire, wind, earth, and water) and therefore also
over the material bodies of future human beings. However, Adam begets
his son Seth in the likeness of the divine Seth, son of Adamas, the
prototype of ideal humanity. The human race is thus spiritually the seed
of Seth, though bodily incarnation at birth entails a forgetting of this
divine origin. The realization of one’s spiritual ancestry must be
reawakened by revelation.
This is a theme from Platonic philosophy, illustrated in the myth of
Er in Plato’s Republic, in which a slain warrior named Er is revived
briefly on his funeral pyre and tells of what he has seen of the fate of
souls after death. The lengthy account includes a description of
reincarnation and of the necessity of each soul to drink of the river of
Forgetfulness before coming into another body. According to the
Apocryphon, until a soul is saved by receiving revelation of its true
identity, it continues to experience further reincarnations. If souls
knowingly reject the revelation, they will suffer eternal damnation.
Several Nag Hammadi texts include myths that are similar to those of
the Apocryphon of John. This tradition has sometimes been labeled
“Sethian” because of the prominent role of the figure of Seth in several
of these works. The origins of this Sethian mythology remain uncertain,
but it may have emerged prior to the birth of Christianity or apart from
Christianity in heterodox Jewish circles; it could then have been
adapted by Christian writers who identified Jesus with the myth’s
original revealer figure. In any event, there is significant diversity
among the so-called Sethian sources, and they are probably best viewed
as products of different stages of a complex series of religious
innovations.

Valentinian gnosticism
The category “gnostic,” however, has conventionally included still other
movements. The most famous of these are the Valentinian traditions that
Irenaeus and other heresiologists discuss at great length and which are
also found among the Nag Hammadi works. The evidence regarding
Valentinus himself is fragmentary but suggests that he was a Christian
mystic with a Platonic approach to the interpretation of scripture. His
contribution to the more elaborate mythologies of the Valentinian
tradition, however, remains uncertain. That tradition typically involves
a myth of the unfolding of the divine perfection in a genealogy of aeons,
the last of whom is Wisdom.
Valentinianism recognizes a demiurge that is produced by Wisdom and
is distinct from the true god. The creator of the material universe and
humanity, the demiurge is not a malevolent figure, as is Ialdabaoth in
the Apocryphon of John. Human beings possess a soul given to them by the
demiurge, a spiritual element provided by Wisdom, and a body made from
matter. The spiritual element, which is sometimes referred to as a
“seed,” is that divine aspect of humans which is capable of eventual
reunion with the spiritual realm. Valentinian sources often use the
image of a school to describe the purpose of one’s existence in this
world. Thus, through the discipline of life in general as well as
through the instruction that was apparently an important aspect of
Valentinian communal life, the spiritual person achieves the maturity
necessary to be restored to the realm of perfection after the physical
death of the body, while the soul remains with the demiurge in an
intermediate place. Some sources distinguish not just three elements
within human beings but also three different human types: spiritual, “soulish,”
and material. Finally, the Valentinian tradition maintains that the role
played by Jesus is primarily instructional: spiritual perfection and
salvation are obtained by recognizing his divine nature and by
discerning the hidden meanings of passages in the Gospels and other
scriptures.

Diversity of gnostic myths
As Valentinian tradition illustrates, the myths usually categorized as
gnostic do not always demonize the creator, as was the case in the
Apocryphon of John. What they share is not necessarily an extreme
hostility toward the creator or the material cosmos but simply an
interpretation of biblical narrative that introduces—in a variety of
ways—inferior creators. For example, the myth that Irenaeus reports for
the early 2nd-century teacher Satornil of Antioch seems to parallel many
elements of the Apocryphon of John. Yet in Satornil’s myth the seven
world-creating angels—one of whom is Yahweh, the God of the
Israelites—are created by the transcendent god and rebel only later.
Another 2nd-century figure, Justin (not to be confused with the more
famous Justin Martyr), taught that there were three original entities, a
transcendent being called the Good, a male intermediate figure named
Elohim (the God of Israel in the Hebrew Bible, or Old Testament), and an
earth-mother figure named Eden or Israel. The world was created from the
love of Elohim and Eden, and the first human couple were also created as
a symbol of this love. Ironically, evil was introduced after Elohim
learned of the existence of the Good above him and abandoned Eden to
ascend to it. The ascent of Elohim entailed pain for Eden, whose
consequent anger brought ills on humankind. Two writings in the Nag
Hammadi library, the Nature of the Archons and On the Origin of the
World, contain a figure named Sabaoth, one of the sons of Ialdabaoth,
who is reminiscent of Justin’s Elohim. When Sabaoth realizes that there
is a higher realm, he undergoes a kind of conversion, condemns
Ialdabaoth, and is enthroned above him.
Marcion of Sinope (born c. ad 110 ) taught a similar myth. He
considered the father of Christ to be completely distinct from the
creator God of Judaism and saw only contrasts between Jewish religion
and the Christian Gospels. Human salvation, announced by Jesus, came
from the father as an offer of pure grace and as a rescue from the
system of the stern creator. The creator in Marcionite doctrine is not
an offspring of a higher realm like Ialdabaoth or the Valentinian
demiurge, and Marcion had no mythology of a special race of humans
descended from a transcendent realm. His doctrine is therefore often
considered to be only a relative of “gnosticism.”
The attraction of these myths lay especially in their solutions to
problems of theodicy (the attempt to reconcile the goodness and justice
of God with the existence of evil in the world), since distinguishing a
lower creator absolved the higher deity from responsibility for evil or
imperfection in the cosmos. These myths also addressed problems
concerning the interpretation of scriptures (including Genesis) in which
human qualities, such as jealously or anger, are ascribed to the
creator. Similar doctrines of lower demiurges were already current in
late Hellenistic philosophy, and for some Christians (and perhaps
earlier for some Jews) an interpretation of biblical tradition along
these lines would have seemed only sensible. Opponents such as Irenaeus,
on the other hand, considered such doctrines to be pagan corruptions of
true monotheism.
Beyond their frequent inclusion of a demiurgical myth, gnostic
sources vary significantly in other respects, though there are
identifiable clusters of sources that have far more in common, such as
the Sethian or Valentinian groups. Very often there is a doctrine of the
preexistence of the soul or spirit, the soul’s incarnation and
imprisonment within the body, its eventual rescue and ascent, and
sometimes its reincarnation—themes that were also common in Platonism or
Neo-Pythagoreanism. These themes also can be found in Christian texts
that lack any myth of a lower demiurge, such as the Exegesis on the
Soul, which appears in the Nag Hammadi collection.
Research on new sources such as those from Nag Hammadi has also
called into question several conventional generalizations about
gnosticism. In the area of ethics, for example, there is little evidence
to support the belief that gnostics were either extreme ascetics or
libertines. Many gnostic traditions are ascetic, but others seem to
assume the institutions of marriage and family. The occasional charges
of libertinistic practices from opponents remain problematic and are
unsupported by original writings such as the Nag Hammadi texts. Language
about a spiritual race or class of humans saved by revelation has often
been understood to imply a characteristic gnostic determinism, yet this
has proven to be another questionable stereotype. The Apocryphon of
John, for example, seems to envision eventual salvation for everyone
except those who knowingly reject the revelation after having received
it. Similarly, although gnosticism is often associated with docetism—the
notion that divine participation in human experience (such as Jesus’s
suffering by crucifixion) is only apparent and not real—the Nag Hammadi
tractate Melchizedek, which displays features of Sethian gnosticism, is
explicitly critical of docetic interpretations of Jesus’ life and
suffering.
Certain writings often labeled “gnostic” have attracted unusual
popular interest but illustrate the difficulties in such classification.
The Nag Hammadi Gospel of Thomas, for example, does not include any
extended mythic narrative, and there is doubt about whether it is
justifiably classified as gnostic. It consists entirely of a series of
secret sayings ascribed to Jesus, several of which have close parallels
in the New Testament Gospels. Although scholars are divided on the
issue, some contend that certain elements of the Gospel of Thomas are
among the oldest witnesses to Jesus’ words. Surviving Greek fragments do
suggest that versions of the Gospel of Thomas existed at least as early
as the 2nd century ad.
A Coptic version of the Gospel of Mary is partially preserved in the
Berlin Codex 8502, and there are two earlier Greek fragments from the
3rd century. This text has evoked much popular interest, primarily for
the prominence it gives to Mary (probably Magdalene, though some have
argued that it is Jesus’ mother), who is privileged here with special
visions not shared by the male apostles. The importance of spiritual
insight appears to be a leading theme in the Gospel of Mary, but what
survives of the writing contains no myth of a lower creator, and there
is disagreement about the gospel’s relation to so-called gnostic
traditions.
The highly debated Gospel of Judas was found in a 4th-century papyrus
manuscript, the Codex Tchacos, which also contained at least three other
writings, two of which were found in the Nag Hammadi collection. The
codex was discovered in Egypt in the 1970s but was subsequently acquired
by and passed among collectors in Europe and the United States for
years. The delay in proper preservation by experts resulted in severe
damage to the manuscript. When the codex was finally published in 2006,
sensational attention swirled around the Gospel of Judas. Although
Irenaeus briefly mentioned a “Gospel of Judas,” no gospel with this name
had been found (and some scholars still question whether the Tchacos
Judas is the same as that referred to by Irenaeus). Public curiosity was
particularly aroused by early suggestions that Jesus in the Tchacos text
praises Judas as a hero rather than calling him a traitor. Subsequent
scholarly analysis, however, resulted in spirited debate on this point.
Some argue that Judas is in fact demonized and is associated with
demiurgical powers in the writing’s elaborate myth, which seems to draw
on traditions similar to those in Sethian works. The poor preservation
of the manuscript has allowed for such disparate analyses. In any event,
this most curious writing is another indisputably important witness to
the sheer diversity among so-called gnostic works.

Influence
Although gnostic movements of various types flourished in the formative
period of Christianity, they were likely a minority in most places. At a
time when there was still no fixed Christian Bible or uniform church
organization, their often elaborate creation myths and eschatologies
constituted some of the earliest attempts at a systematic articulation
of Christian beliefs. Fundamental features of what eventually became
Christian orthodoxy were shaped through controversy over such doctrines.
For example, the arguments by which orthodox Christians defended so
basic a doctrine as that Jesus was the son of the same God who gave the
Torah to Moses were forged amid polemic against demiurgical myths such
as those found in the Nag Hammadi writings. The orthodox creed that
Jesus truly suffered and yet was fully divine as well as fully human was
decisively influenced by early controversies over views found in
Valentinian and similar traditions, which seemed to deny any real human
incarnation to the divine Saviour.
Similar mythological traditions were also important in the formation
of Manichaeism, a dualistic religious movement founded by the Iranian
preacher Mani in the 3rd century ad and which survived for a millennium.
Although Mani was persecuted and eventually martyred by Persian
authorities, Manichaeism spread to the western Mediterranean and as far
east as China and during the 8th–9th centuries was even embraced by
Uighur rulers.
Modern Mandaean communities were formerly concentrated in southern
Iraq and in Iran, but by the beginning of the 21st century persecutions
had forced most of the perhaps 70,000 members of this ethnic group into
diaspora communities all over the world. Some researchers argue that the
roots of the complex mythology, baptisms, and other rituals practiced by
modern Mandaeans are traceable to late antiquity and bear kinship with
Sethian and ancient Manichaean myths. The Mandaeans may therefore be the
“last gnostics.”
