Gnostic in the context of "Akbarism"

The Albigensian Crusade (French: Croisade des albigeois), also known as the Cathar Crusade (1209–1229), was a military and ideological campaign initiated by Pope Innocent III to eliminate Catharism in Languedoc, what is now southern France. The Crusade was prosecuted primarily by the French crown and promptly took on a political aspect. It resulted in the significant reduction of practicing Cathars and a realignment of the County of Toulouse with the French crown. The distinct regional culture of Languedoc was also diminished.

The Cathars originated from an anti-materialist reform movement within the Bogomil churches of the Balkans calling for what they saw as a return to the Christian message of perfection, poverty and preaching, combined with a rejection of the physical. The reforms were a reaction against the often perceived scandalous and dissolute lifestyles of the Catholic clergy. Their theology, Gnostic in many ways, was basically dualist. Several of their practices, especially their belief in the inherent evil of the physical world, conflicted with the doctrines of the Incarnation of Christ and Catholic sacraments. This led to accusations of Gnosticism and attracted the ire of the Catholic establishment. They became known as the Albigensians because many adherents were from the city of Albi and the surrounding area in the 12th and 13th centuries.

Irenaeus (/ɪrɪˈneɪəs/ or /ˌaɪrɪˈniːəs/; Ancient Greek: Εἰρηναῖος, romanized: Eirēnaîos; c. 125 – c. 202 AD) was a Greek bishop noted for his role in guiding and expanding Christian communities in the southern regions of present-day France and, more widely, for the development of Christian theology by opposing Gnostic interpretations of Christian Scripture and defending orthodoxy. Originating from Smyrna, he had seen and heard the preaching of Polycarp, who in turn was said to have heard John the Evangelist.

Chosen as Bishop of Lugdunum, now Lyon, Irenaeus wrote his best-known work Against Heresies around 180 as a refutation of gnosticism, in particular that of Valentinus. To counter the doctrines of the gnostic sects claiming secret wisdom, he offered three pillars of orthodoxy: the scriptures, the tradition said to be handed down from the apostles, and the teaching of the apostles' successors. He is the earliest surviving witness to regard all four of the now-canonical gospels as essential.

In some Gnostic systems, the supreme being is known as the Monad, the One, the Absolute, Aiōn Teleos (the Perfect Aeon, αἰών τέλεος), Bythos (Depth or Profundity, Βυθός), Proarchē (Before the Beginning, προαρχή), Hē Archē (The Beginning, ἡ ἀρχή), the Ineffable Parent, and/or the Primal Father. The Monad is an adaptation of concepts of the monad in Greek philosophy to Christian belief systems.

The Apocryphon of John, written c. 120 CE, gives the following description:

The Elcesaites, Elkasaites, Elkesaites or Elchasaites were an ancient Jewish Christian sect in Lower Mesopotamia, then the province of Asoristan in the Sasanian Empire that was active between 100 and 400 CE. The members of this sect, which originated in the Transjordan, performed frequent baptisms for purification and had a Gnostic orientation.

The movement blended elements of Second Temple Judaism, early Jewish Christianity, Gnosticism, and apocalyptic mysticism, and it is primarily known through the writings of early Church Fathers such as Hippolytus of Rome, Origen, and Epiphanius of Salamis.

The Gospel of Thomas (also known as the Coptic Gospel of Thomas) is a non-canonical sayings gospel. It was discovered near Nag Hammadi, Egypt, in 1945 among a group of books known as the Nag Hammadi library. Scholars speculate the works were buried in response to a letter from Bishop Athanasius declaring a strict canon of Christian scripture. Most scholars place the composition during the second century, while some have proposed dates as late as 250 AD and others have traced its signs of origins back to 60 AD. Some scholars have seen it as evidence of the existence of a "Q source" that might have been similar in its form as a collection of sayings of Jesus, without any accounts of his deeds or his life and death, referred to as a sayings gospel, though most conclude that Thomas depends on or harmonizes the Synoptics.

The Coptic-language text, the second of seven contained in what scholars have designated as Nag Hammadi Codex II, comprises 114 sayings attributed to Jesus. Almost two-thirds of these sayings resemble those found in the canonical gospels and its editio princeps counts more than 80% of parallels. Experts speculate that the gospel's other sayings were added from Gnostic tradition. Its place of origin may have been Syria, where Thomasine traditions were strong. Other scholars have suggested an Alexandrian origin.
