I have said much here about the Russian Orthodox missionaries in China because they spilled their blood in martyrdom in 1900, along with their Roman Catholic brothers and sisters in China. Few Catholics are aware, however, that Eastern Catholics, too, have lived and worshipped in China. As Father Sergiy informed a Greek Orthodox visitor who was sharing tea with us, the only discernable difference between Eastern Catholics and Eastern Orthodox is that Catholics pray for the Pope during the Divine Liturgy (Eastern Catholics, of course, are in full communion with the Holy Father and Rome, unlike Eastern Orthodox). In the 1937 Jesuit-published A Guide to Catholic Shanghai, the Russian Catholic Chapel with a photograph of its spectacular iconostasis is featured on page 20. Eastern Catholic priests celebrated the Byzantine Liturgy in Old Slavonic there, with a burgeoning parish of some 260 Russians. Sadly, tensions between the Catholic Byzantine and Orthodox faithful exacerbated relations between the two communities in Shanghai, though today it is even more regrettable that neither the Eastern Catholic nor Orthodox churches are in use at all; I have walked by the old Russian church many times in Shanghai, and have each time lamented its current state of decay from long neglect.
very good article (in The Catholic World Report, no less) - thanks for posting!
