ValentinianismValentinianism was one of the major Gnostic Christian movements. Founded by Valentinus in the 2nd century AD, its influence spread widely, not just within Rome but also from Northwest Africa to Egypt through to Asia Minor and Syria in the East. Later in the movement's history it broke into an Eastern and a Western school. Disciples of Valentinus continued to be active into the 4th century AD, after the Roman Emperor Theodosius I issued the Edict of Thessalonica (380 AD), which declared Nicene Christianity as the State church of the Roman Empire.
Early ChristianityEarly Christianity, or Paleochristianity, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians. Early Christianity contains the Apostolic age and is followed by, and substantially overlaps with, the Patristic era.
PleromaPleroma (πλήρωμα, literally "fullness") generally refers to the totality of divine powers. It is used in Christian theological contexts, especially in Gnosticism. The term also appears in the Epistle to the Colossians, which is traditionally attributed to Paul the Apostle. The word is used 17 times in the New Testament. The word literally means "fullness", from the verb (πληρόω, "to fill"), from (πλήρης, "full"). The word itself is a relative term, capable of many shades of meaning, according to the subject with which it is joined and the antithesis to which it is contrasted.
GnosisGnosis is the common Greek noun for knowledge (γνῶσις, gnōsis, f.). The term was used among various Hellenistic religions and philosophies in the Greco-Roman world. It is best known for its implication within Gnosticism, where it signifies a spiritual knowledge or insight into humanity's real nature as divine, leading to the deliverance of the divine spark within humanity from the constraints of earthly existence. Gnosis is a feminine Greek noun which means "knowledge" or "awareness.
HeracleonHeracleon was a Gnostic who flourished about AD 175, probably in the south of Italy. He is described by Clement of Alexandria (Strom. iv. 9) as the most esteemed (δοκιμώτατος) of the school of Valentinus; and, according to Origen (Comm. in S. Joann. t. ii. § 8, Opp. t. iv. p. 66), said to have been in personal contact (γνώριμος) with Valentinus himself. He is barely mentioned by Irenaeus (2.4.1) and by Tertullian (adv. Valent. 4). The common source of Philaster and Pseudo-Tertullian (i.e.
CerinthusCerinthus (Kērinthos; fl. c. 50-100 CE) was an early Gnostic, who was prominent as a heresiarch in the view of the early Church Fathers. Contrary to the Church Fathers, he used the Gospel of Cerinthus, and denied that the Supreme God made the physical world. In Cerinthus' interpretation, the Christ descended upon Jesus at baptism and guided him in ministry and the performing of miracles, but left him at the crucifixion. Similarly to the Ebionites, he maintained that Jesus was not born of a virgin, but was a mere man, the biological son of Mary and Joseph.
Nag Hammadi libraryThe Nag Hammadi library (also known as the "Chenoboskion Manuscripts" and the "Gnostic Gospels") is a collection of early Christian and Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945. Thirteen leather-bound papyrus codices buried in a sealed jar were found by a local farmer named Muhammed al-Samman. The writings in these codices comprise 52 mostly Gnostic treatises, but they also include three works belonging to the Corpus Hermeticum and a partial translation/alteration of Plato's Republic.
Sophia (Gnosticism)Sophia (Σοφíα "Wisdom", ⲧⲥⲟⲫⲓⲁ "the Sophia") is a major theme, along with Knowledge (γνῶσις gnosis, Coptic ), among many of the early Christian knowledge-theologies grouped by the heresiologist Irenaeus as (γνωστικοί), "knowing" or "men that claimed to have deeper wisdom". Gnosticism is a 17th-century term expanding the definition of Irenaeus' groups to include other syncretic and mystery religions. In Gnosticism, Sophia is a feminine figure, analogous to the human soul but also simultaneously one of the feminine aspects of God.
BasilidesBasilides (Greek: Βασιλείδης) was an early Christian Gnostic religious teacher in Alexandria, Egypt who taught from 117 to 138 AD, and claimed to have inherited his teachings from the apostle Saint Matthias. He was a pupil of either the Simonian teacher Menander, or a supposed disciple of Peter named Glaucias. The Acts of the Disputation with Manes state that for a time he taught among the Persians. According to Agapius of Hierapolis he appeared in the 15th year of Trajan reign (113 AD).
Marcion of SinopeMarcion of Sinope (ˈmɑrkiən,_-siən; Μαρκίων Σινώπης; 85-160) was an early Christian theologian in early Christianity. Marcion preached that God had sent Jesus Christ, who was an entirely new, alien god, distinct from the "vengeful" God (Demiurge) who had created the world. He considered himself a follower of Paul the Apostle, whom he believed to have been the only true apostle of Jesus Christ; his doctrine is called Marcionism. Marcion published the earliest record of a canon of New Testament books.
