What is "chaldean catholic church"

n. An eastern Church that is part of the Roman Catholic Church

The Chaldean Catholic Church (, ʿīdtha kaldetha qāthuliqetha; Arabic: الكنيسة الكلدانية al-Kanīsa al-kaldāniyya) is an Eastern Syriac particular church of the Catholic Church, under the Holy See of the Catholicos- Patriarch of Babylon, maintaining full communion with the Bishop of Rome and the rest of the Catholic Church. The Chaldean Catholic Church presently comprises around 500,000 people. Most Chaldo-Assyrians live in northern Iraq, with smaller numbers in adjacent areas in northeastern Syria, southeastern Turkey and northwestern Iran, a region roughly corresponding with what was Assyria between the 25th century BC and mid-7th century AD. There are also Chaldeans in the diaspora, primarily in the American states of Michigan, Illinois and California.

Despite being known as "Chaldeans", their followers are generally accepted to be one and the same as the indigenous Eastern Aramaic-speaking Assyrians, although a minority of Chaldeans (particularly in the United States) have in recent times began to espouse an identity from the land of Chaldea, extant in south east Mesopotamia between the 9th and 6th centuries BC, despite there being no accredited academic study or historical record which supports this.

In addition to this church, other ethnically Assyrian Churches include The Assyrian Church of the East, The Ancient Church of the East, The Syriac Orthodox Church, The Syriac Catholic Church, The Assyrian Pentecostal Church and The Assyrian Evangelical Church.
