Ieso, the Tazig name for Jesus in the original materials behind the Arabic Quran comes from the original Koine Greek form Iesous (but without the Greek "-us" suffix). It is the only way the Persians have ever referred to Jesus.
Just like other types of Manicheanism, Tazig lore says Jesus possesses three separate identities:
(1) Jesus the Messianic Emmisary (the true body of Christ called ahmed)
(2) Jesus the Suffering Word (patibilis the appearance referred to as mahmad)
(3) Jesus the Luminous Spirit
