To this day, being a high-church Byzantine Catholic* is a kind of living martyrdom: many Orthodox, many/most RCs (left and right) and other BCs are gunning for you.

It’s like the Anglo-Catholic experience: regarded as imposters, or hated for theological and liturgical traditionalism, perhaps patronised by the mainstream, sometimes in the name of ecumenism.

Все святые Руси, молите Бога о нас!

*Истиный восточник: a conservative with no latinisations in church, somebody who learns the rite and its language(s) and defends them from encroachments (and because of that is often accused of preaching schism).
