You say "Western Trinitarian Church" as if there was a Western non-Trinitarian alternative.
Anyway, I think the reasons for the Western-centric mindset are actually better justified than just being down to ignorance or narrow-mindedness. The Orthodox/Coptic churches were far smaller than the Western Church in terms of their political power and their following. But the point of real significance is that they failed to make any contribution at all to either Christian theology or political thought. They let themselves become irrelevant on the wider Christian scene.
