Though Persia/Iran had never been a Christian country, Christianity had enough of an impact on Persia and Persians to produce a considerable number of saints of this origin, at various times in the Church's history – some of them travelling far afield from their native country, such as Saint Ivo of Huntingdonshire who got his fame as a hermit in England.
In modern times, some with connections to Iran have been proposed for canonization. Among these are:
- Servants of God Ibrahim Addai Scher (d. 1918) and 27 Companion Martyrs of the Assyrian-Chaldean-Syriac Genocide (d. 1915-18), Archeparchs, Eparchs, Priests, Catechumens, and Laypersons of the Archeparchy of Urmia; Priests of the Congregation of the Mission (Vincentians); Martyrs (Iraq-Iran)
