Bardesanian (System). The “Codex of the Nazarenes”, a system worked out by one Bardesanes. It is called by some a Kabala within the Kabala; a religion or sect the esotericism of which is given out in names and allegories entirely sui-generis. A very old Gnostic system. This codex has been translated into Latin. Whether it is right to call the Sabeanism of the Mendaїtes (miscalled St. John’s Christians), contained in the Nazarene Codex, “the Bardesanian system”, as some do, is doubtful; for the doctrines of the Codex and the names of the Good and Evil Powers therein, are older than Bardaisan. Yet the names are identical in the two systems.
