Christian Nondualism

Gnostic Christianity is usually understood to be a dualistic movement; however, recent discoveries, including the Gospel of Thomas, have led some scholars to believe that Jesus' original teaching may have been one accurately characterized as nondualism.

The Gospel of Philip, another of the Apocryphal books, also conveys nondualism:
"Light and Darkness, life and death, right and left, are brothers of one another. They are inseparable. Because of this neither are the good good, nor evil evil, nor is life life, nor death death. For this reason each one will dissolve into its earliest origin. But those who are exalted above the world are indissoluble, eternal."
