I guess its time for a Chaldean to post in this repetitive thread. My apologies to the OP.
History shows that Chaldeans and Assyrians are descended from Akkadians, Sumerians, and Aramaeans. Aramaeans were from modern day Syria. Akkadians and Sumerians from Mesopotamia.
Maronites and Syriacs, and possibly Melkites, are descended from Phoenicians (Lebanon) and Aramaeans. The Aramaic culture being the common element and dominant aspect of our cultures is what keeps these four “identities” in common with each other. I don’t mean to sound like a know-it-all but this is confirmed by genealogical DNA tests.
None of the aforementioned ethnic and historic backgrounds descend from Arab, Arabian, or Jewish ancestry, but it is rather the opposite. Seeing as Jews claim to be descendants of Jacob, who was the grandson of Abraham, who was from Ur of Chaldea (southern Mesopotamia), and Arabs claim to be descended from Ishmael, son of Abraham, it wouldn’t make any sense to call the Aramaic ethnicites as Arabs.
Currently Syriac (modern day Aramaic) is the mother tongue of Chaldean, Assyrians, and Syriacs. Aramaic is also the primary liturgical language for the Maronite, Chaldean, Assyrian, and Syriac churches. Due to the disgusting pan-Arab movements of the past century, and hundreds more years of oppression by Muslims, many of these Aramaic people aren’t fluent in their mother tongue, but Arabic. This is sadly especially true for Maronites, even though mostly clergy are taught to be fluent in the Syriac language.
BTW Saint Abo of Tbilisi was originally a Muslim Baghdadi, who converted to Christianity, so I guess he counts as an Arab saint.
