Is There an Ur Tradition?

Had time to look up something that I had been considering but had put aside.

Latin polemics against Orthodox tradition on divorce and remarriage generally focus exclusively on the Byzantines, arguing that the tradition was a human innovation arising from capitulation to human weakness and state pressure or accomodation. Those polemicists do not look at divorce and remarriage within the Oriental Orthodox and Assyrian Churches.

So I took a quick look -- it appears that there is ecclesiastical divorce (and remarriage) in at least the Assyrian, Armenian, Syro-Malankara/Syriac Orthodox, and Coptic Churches. So how would the Latins respond to that? Most likely: "Only Rome has maintained the purity of the Apostolic Tradition, because the pope is the sucessor of St. Peter!"

Is the origin of the Latin tradition on divorce and remarriage linked to the origin of the Latin tradition on clerical continence/celibacy? Latin polemicists, again: "Apostolic Tradition!"
