Chaldean Catholic Church 加色丁礼天主教会

The Chaldean Catholic Church (Syriac:ܥܕܬܐ ܟܠܕܝܬܐ ܩܬܘܠܝܩܝܬܐ‎, ʿītha 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 an estimated 500,000 people in northern Iraq, and adjacent areas in north east Syria, south east Turkey and north west Iran, a region roughly corresponding with what was Assyria between the 25th century BC and mid-7th century AD.
