The Gospel of Thomas is an extra-canonical sayings gospel. It was discovered near Nag Hammadi, Egypt, in December 1945 among a group of books known as the Nag Hammadi library. Scholars speculate that the works were buried in response to a letter from Bishop Athanasius declaring a strict canon of Christian scripture. Scholars have proposed dates of composition as early as 60 AD and as late as 250 AD. Since its discovery, many scholars have seen it as evidence in support of the existence of a "Q source" which might have been very 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.

In Cairo, in January 1896, Carl Reinhardt bought the codex, which had been recently discovered, wrapped in feathers, in a niche in a wall at a Christian burial site.

The Apocryphon of John, also called the Secret Book of John or the Secret Revelation of John, is a 2nd-century Sethian Gnostic Christian pseudepigraphical text attributed to John the Apostle. It is one of the texts addressed by Irenaeus in his Against Heresies, placing its composition before 180 AD. It is presented as describing Jesus appearing and giving secret knowledge (gnosis) to his disciple John. The author describes it as having occurred after Jesus had "gone back to the place from which he came".
The Gospel of Judas is a non-canonical Gnostic gospel. The content consists of conversations between Jesus and Judas Iscariot. Given that it includes late 2nd-century theology, it is widely thought to have been composed in the 2nd century by Gnostic Christians. The only copy of it known to exist is a Coptic language text that has been carbon dated to 280 AD, plus or minus 60 years. It has been suggested that the text derives from an earlier manuscript in the Greek language. An English translation was first published in early 2006 by the National Geographic Society.
The Sethians were one of the main currents of Gnosticism during the 2nd and 3rd century AD, along with Valentinianism and Basilideanism. According to John D. Turner, it originated in the 2nd century AD as a fusion of two distinct Hellenistic Judaic philosophies and was influenced by Christianity and Middle Platonism. However, the exact origin of Sethianism is not properly understood.
Allogenes is a series of Gnostic texts. The main character in these texts is Allogenes, which translates as 'stranger,' 'foreigner,' or 'of another race.' The first text discovered was Allogenes as the third tractate in Codex XI of the Nag Hammadi library. The Coptic manuscript is a translation of a Greek original, likely written in Alexandria before 300 AD. In this text, containing Middle Platonic or Neoplatonic elements, Allogenes receives divine revelations.
