Sure, here are the links. The relevant articles are mostly from my blog, which I've been writing on since 2011 until I switched to Medium a year ago.
The first is a dialogue I wrote between a Catholic and an Eastern Christian (modeled on David Bentley Hart). The next two talk about the deeper meaning of both kinds of Christianity. (In a later Medium article I return to the subject of one of those two articles, on Christianity's relation to the Axial revolutions, but I ignore the complication of Eastern vs Western Christianity and focus on the latter. I include a link to it for comparison's sake.)
The last one is a long survey on the meaning of the world's religions, which includes a section "Western and Eastern Christianity" (scroll down to the halfway point).
