Leucius Charinus was, according to tradition, a disciple of St. John the Divine and the author of the Leucian Acts, a series of apocryphal Gnostic texts dating to the mid second-century.
The Leucian Acts were most likely redacted at a later date to express a more orthodox view. Of the five, the Acts of John and Thomas have the most remaining Gnostic content.
LeuciusCharinus is the name given by church writers to the supposed author of the Apocryphal Acts of John, Paul, Peter, Andrew, and Thomas.
And looking up together unto heaven they made the seal of the cross with their fingers upon their tongues, and forthwith they spake both of them, saying: Give us each a volume of paper, and let us write that which we have seen and heard.
And when all the synagogue of the Jews heard all these marvelous sayings of Karinus and Leucius, they said one to another: Of a truth all these things were wrought by the Lord, and blessed be the Lord, world without end, Amen.
LeuciusCharinus was, according to the Catholic church, the author of the Leucian Acts, a series of pseudoepigraphal (falsely-attributed) Gnostic texts of the late second-century.
Charinus is by some scholars believed to be the founder and originator of Gnosticism, and his texts are among the earliest documents related to this religious movement.
The main source for the attribution of these texts to LeuciusCharinus is his refutation by Irenaeus in Against Heresies, written 180 AD.
