Eastern Orthodoxy by country
Based on the numbers of adherents, the Eastern Orthodox Church (also known as Eastern Orthodoxy) is the second largest Christian communion in the world after the Roman Catholic Church. The most common estimates of the number of Eastern Orthodox Christians worldwide is approximately 200–260 million. The numerous Protestant groups in the world, if taken all together, outnumber the Eastern Orthodox, but they differ theologically and do not form a single communion.
Eastern Orthodoxy in Estonia
The Orthodox community in Estonia, which accounts for about 16.5% of the total population as of 2011, which has become largest Christian denomination in the country over Lutheranism for the first time in country's modern history, remains divided, with the majority of faithful (mostly ethnic Russians) remaining under Moscow. As of a government report in 2004, about 20,000 believers (mostly ethnic Estonians) in 54 parishes are part of the Estonian Apostolic Orthodox autonomous church under Constantinople, while 150,000 faithful in 30 parishes, along with the monastic community of Pühtitsa, are with the Moscow Patriarchate.
