The word '''Tsabians''' (Σοβιαΐ) refers to the Oriental Orthodox believers described as Mithrean Messianic Noahites. The original Mithrean Noahites were called [[Mages]] while the word Tsabi is closer to Sebomenoi (Σεβομενοι), the Greek word for Noahites which was Tarsak (pl. Tarsakan)in Persian.
The Arabic term Tsabi (Mithrean Messianic Noahites) or its Greek plural Sobiai also referred to Ekhasai's "Hearers" (ismai'i) or the Manicheans' uninitiated audience which has caused all Sobiai to be often simply (and inaccurately) referred to as Manicheans even if they were not aware of the "Great Secret" of Mani's Gnosticism. The Persian words for such Tsabis was [[Tazig|Tazig, (pl. Tazigan)]] and [[Nighòshagàn]].
