Gospel of Thomas in the context of Q source

The 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.

Twelve leather-bound papyrus codices (and a tractate from a thirteenth) buried in a sealed jar were found by an Egyptian farmer named Muhammed al-Samman and others in late 1945. The writings in these codices comprise 52 mostly Gnostic treatises, but also three works belonging to the Corpus Hermeticum, and a partial translation/alteration of Plato's Republic. In his introduction to The Nag Hammadi Library in English, James Robinson suggests that these codices may have belonged to a nearby Pachomian monastery and were buried after Saint Athanasius condemned the use of non-canonical books in his Festal Letter of 367 A.D. The Pachomian hypothesis has been further expanded by Lundhaug & Jenott (2015, 2018) and further strengthened by Linjamaa (2024). In his 2024 book, Linjamaa argues that the Nag Hammadi library was used by a small intellectual monastic elite at a Pachomian monastery, and that they were used as a smaller part of a much wider Christian library.

Acts of Thomas is an early 3rd-century text, one of the New Testament apocrypha within the Acts of the Apostles subgenre. The complete versions that survive are Syriac and Greek. There are many surviving fragments of the text. Scholars detect from the Greek that its original was written in Syriac, which places the Acts of Thomas in Edessa, likely authored before 240 AD. The surviving Syriac manuscripts, however, have been edited to purge them of the most unorthodox overtly Encratite passages, so that the Greek versions reflect the earlier tradition. The earliest external reference to the Acts of Thomas dates to c.225 in Origen's Exegesis on Genesis, although this text is now lost and its citation survives via later texts, e.g. Eusebius of Caesarea's Ecclesiastical History (3.1.1–3).

Fragments of four other cycles of romances around the figure of the apostle Thomas survive, but this is the only complete one. It should not be confused with the early "sayings" Gospel of Thomas. "Like other apocryphal acts combining popular legend and religious propaganda, the work attempts to entertain and instruct. In addition to narratives of Thomas' adventures, its poetic and liturgical elements provide important evidence for early Syrian Christian traditions," according to the Anchor Bible Dictionary.

Matthew 10 is the tenth chapter in the Gospel of Matthew in the New Testament section of the Christian Bible. This chapter opens with Jesus calling some of his disciples and sending them out to preach and heal. This chapter is also known as the Mission Discourse, the Apostolic Discourse, or the Little Commission, in contrast to the Great Commission at the end of the gospel (Matthew 28:18–20). The Apostles receiving the Little Commission are directed to enter only the towns of the "lost sheep of the house of Israel" in verse 6, but verse 18 mentions that they will also be a witness to "governors, kings and the Gentiles" while in those towns. In contrast, the Great Commission is specifically directed to all nations. This has led to debate as to whom the target audience of Jesus' original, pre-resurrection ministry was.

Matthew names the twelve apostles, or "twelve disciples", in verses 2 to 4, and gives them careful instruction as they travel around Israel. The remainder of the chapter consists almost entirely of sayings attributed to Jesus. Many of the sayings found in Matthew 10 are also found in Luke 10 and the Gospel of Thomas, which is not part of the accepted canon of the New Testament.

The Parable of the Mustard Seed is one of the shorter parables of Jesus. It appears in Matthew (13:31–32), Mark (4:30–32), and Luke (13:18–19). In the Gospels of Matthew and Luke, it is immediately followed by the Parable of the Leaven, which shares this parable's theme of the Kingdom of Heaven growing from small beginnings. It also appears in the non-canonical Gospel of Thomas (verse 20).

The term logia (Greek: λόγια), plural of logion (Greek: λόγιον), is used variously in ancient writings and modern scholarship in reference to communications of divine origin. In pagan contexts, the principal meaning was "oracles", while Jewish and Christian writings used logia in reference especially to "the divinely inspired Scriptures". A famous and much-debated occurrence of the term is in the account by Papias of Hierapolis on the origins of the canonical Gospels. Since the 19th century, New Testament scholarship has tended to reserve the term logion for a divine saying, especially one spoken by Jesus, in contrast to narrative, and to call a collection of such sayings, as exemplified by the Gospel of Thomas, logia.

Thomasine is a name given to a Syrian Christian group that originated in the first or the second century, who especially revered the apostle Thomas and some scholars speculate to have written the gospel of Thomas. They did not refer to their writing on the life of Jesus as an "εὐαγγέλιον" (euangélion); rather they seem to have preferred the word logia, meaning a book of sayings, as both the genre of their work which makes their approach different from the other early Christian authors. The group was said to have held esoteric, mystical, and ascetic ideas. Some have associated them with the proto-Gnostics. However modern critics have disputed their affiliation with Gnosticism, especially because they lack many uniquely Gnostic beliefs.

Nag Hammadi Codex II (designated by siglum CG II) is a papyrus codex with a collection of early Christian Gnostic texts in Coptic (Sahidic dialect). The manuscript has survived in nearly perfect condition. The codex is dated to the 4th century. It is the only complete manuscript from antiquity with the text of the Gospel of Thomas.

Infancy gospels (Greek: protoevangelion) are a genre of religious texts that arose in the 2nd century. They are part of New Testament apocrypha, and provide accounts of the birth and early life of Jesus. The texts are of various and uncertain origin, and are generally non-canonical in major modern branches of Christianity. They include the Gospel of James, which introduces the concept of the Perpetual Virginity of Mary, and the Infancy Gospel of Thomas (not to be confused with the unrelated Gospel of Thomas), both of which cover many miraculous incidents from the life of Mary and the childhood of Jesus that are not included in the canonical gospels. Although the Life of John the Baptist focuses on John the Baptist rather than Jesus or his immediate family, it is also included in the genre as its events would be contemporary with Jesus's early life.
