Read about Orthodox Christian Churches
The Orthodox Church, officially called the Orthodox Catholic Church and commonly referred to as the Eastern Orthodox Church, is the second largest Christian denomination in the world, with an estimated 300 million adherents. It is said to be the One, Holy, Catholic and Apostolic Church established by Jesus Christ and his Apostles almost 2,000 years ago.
The Orthodox Church is composed of several self-governing ecclesial bodies, each geographically and nationally distinct but theologically unified. Each self-governing (or autocephalous) body, often but not always encompassing a nation, is shepherded by a synod of bishops whose duty, among other things, is to preserve and teach the Apostolic and patristic traditions and related church practices.
The goal of Orthodox Christians from baptism is to continually draw themselves nearer to God throughout their lives. This process is called theosis, or deification, and is a spiritual pilgrimage in which each person strives to both become more holy and more "Christ Like" within Jesus Christ.
The Biblical text used by the Orthodox includes the Greek Septuagint and the New Testament. It includes the seven Deuterocanonical Books and a small number of other books that are in neither Western canon. Orthodox Christians use the term "Anagignoskomena" (a Greek word that means "readable", "worthy of reading") for the ten books that they accept but that are not in the Protestant 39-book Old Testament canon. They regard them as venerable, but on a lesser level than the 39 books of the Hebrew canon. They do, however, use them in the Divine Liturgy. Orthodox Christians believe scripture was revealed by the Holy Spirit to its inspired human authors. The scriptures are not, however, the source of the traditions associated with the Church but rather the opposite; The biblical text came out of that tradition. It is also not the only important book of the Church. There are literally hundreds of early patristic writings that form part of Church tradition.[1]
