The Russian Orthodox Church on Monday officially broke communion with the Orthodox Church of Constantinople, whose patriarch has held the title “first among equals” for nearly a thousand years, following the East–West schism of 1054 — the schism that separated Roman Catholicism and Eastern Orthodoxy. If communion between Moscow and Constantinople is not reinstated, the schism would be the largest in nearly a millennium. Typically, questions of church are a purely ecclesiological matter, but in this case politics seems to have taken the reins of the discussion.
