A new book from Oxford looks interesting: Orthodox Christianity: A Very Short Introduction, by Edward Siecienski (Stockton University). The book seems to address only Eastern, as opposed to Oriental Orthodoxy, that is, the Chalcedonian churches that derive from the Byzantine experience (Greeks, Russians, and so on), rather than the Non-Chalcedonian churches (Armenians, Copts, Ethiopians, and so on). Well, the title does say it’s a “short” introduction. Here’s the description from the publisher’s website:

To many in the West, Orthodoxy remains shrouded in mystery, an exotic and foreign religion that survived in the East following the Great Schism of 1054 that split the Christian world into two camps–Catholic and Orthodox. However, as the second largest Christian denomination, Orthodox Christianity is anything but foreign to the nearly 300 million worshippers who practice it. For them, Orthodoxy is a living, breathing reality; a way of being Christian ultimately rooted in the person of Jesus and the experience of the early Church. Whether they are Greek, Russian, or American, Orthodox Christians are united by a common tradition and faith that binds them together despite differences in culture. True, the road has not always been smooth — Orthodox history is littered with tales of schisms and divisions, of persecutions and martyrdom, from the Sack of Constantinople, capital of the Byzantine Empire and seat of the Ecumenical Patriarch, to the experience of the Russian Orthodox Church under the Soviet Union. Still, today Orthodoxy remains a vibrant part of the religious landscape, not only in those lands where it has made its historic home (Greece, Russia, the Middle East, and Eastern Europe), but also increasingly in the West. Orthodox Christianity: A Very Short Introduction explores the enduring role of this religion, and the history, beliefs, and practices that have shaped it.
