Churches in Iran
"A number of Christian denominations are represented in Iran. Many members of the larger, older churches belong to ethnic groups with their own distinctive culture and language. The members of the newer, smaller churches are drawn both from the traditionally Christian ethnic minorities and to an increasingly larger degree converts from non-Christian background.
The main Christian churches are:
Armenian Apostolic Church of Iran (about 110,000-300,000 adherents),[citation needed]
Assyrian Church of the East of Iran (about 11,000 adherents),
Chaldean Catholic Church of Iran (about 7,000 adherents),
various Protestant denominations, most important of which are:
Presbyterian, including the Assyrian Evangelical Church
Jama'at-e Rabbani (the Iranian Assemblies of God churches)
and the Anglican Church of Iran."
