The Eastern Orthodox Church is one of two churches that were created by the east/west split of Christianity in 1054. (The other was the Catholic Church .) It includes the Orthodox Churches of Russia, Greece, Romania, and other "eastern" countries. The Orthodox Churches have similar beliefs to the Catholic Church: it is hierarchical (at least within each of the national churches), believes in the seven sacraments, holds to the decisions of the early Church Councils (such as Nicea ) and the importance of the Church as a teaching authority , and emphasizes the importance of priests and liturgy. They also make extensive use of icons in personal devotion.
