Theological Opinions

[Last Child of Ungoliant]

orthodox is basically 'established' or 'traditional', tho of course russian and greek and armenian orthodox churches aren't that - the original christianity was coptic, of the form still practised in ethiopia, BTW ethiopia aka Abyssinia was the first state or nation to adopt christianity as it's official religion, though the romans soon followed suit

there are also orthodox jews - dont know much about this, maybe RtB can help
