Parpola, Simo (17 december 2004). ”Assyrian Identity in Ancient Times and Today” (på engelska) (PDF). Journal of Assyrian Academic Studies. sid. 17. http://www.aina.org/articles/assyrianidentity.pdf. ”From the third century AD on, the Assyrians embraced Christianity in increasing numbers, even though the Assyrian religion persisted in places like Harran at least until the tenth, in Mardin even until the 18th century AD (Chwolsohn 1856, 151-156). The single-minded adherence to the Christian faith from late antiquity until the present time has made Christianity an indelible part of Assyrian identity, but it has also subjected the Assyrians to endless persecutions and massacres, first in the hands of the Romans, then in the hands of the Sasanian Persians, and last in the hands of Arabs, Kurds and Turks. These persecutions and massacres have reduced the total number of Assyrians from an estimated 20 million or more in antiquity to well under two million today.”

”Chaldean Christians” (HTML). Catholic Encyclopedia. http://www.newadvent.org/cathen/03559a.htm. Läst 1 november 1908. ”The name of former Nestorians now reunited with the Roman Church. Strictly, the name of Chaldeans is no longer correct; in Chaldea proper, apart from Baghdad, there are now very few adherents of this rite, most of the Chaldean population being found in the cities of Kerkuk, Arbil, and Mosul, in the heart of the Tigris valley, in the valley of the Zab, in the mountains of Kurdistan. It is in the former ecclesiastical province of Ator (Assyria) that are now found the most flourishing of the Catholic Chaldean communities. The native population accepts the name of Atoraya-Kaldaya (Assyro-Chaldeans) while in the neo-Syriac vernacular Christians generally are known as Syrians.”
Lundberg, Dan. ”A virtual Assyria: Christians from the Middle East” (på engelska) (HTML). http://old.visarkiv.se/online/assyria/virtual_assyria_5middleeast.html. ”The dividing line in Sweden between Syrians and Assyrians lies between the religiously defined group: Syrians, who are Syrian Orthodox Christians, and the politically or ethnically determined category: Assyrians, whose members belong to several different Christian beliefs (the majority are of course also Syrian Orthodox Christians) but whose religious affiliation is toned down.”
