The Orthodox Church is one of the oldest religious institutions in the world, it has played a prominent role in the history and culture of Eastern Europe, Greece (including Anatolia), the Caucasus, and the Near East. The Orthodox Church has no central doctrinal or governance authority analogous to the Roman Catholic Church’s pope.
The Eastern Orthodox Church teaches that it is the One, Holy, Catholic and Apostolic Church established by Jesus Christ in his Great Commission and that its bishops are the successors of Christ’s apostles. It maintains that it practices the original Christian faith, passed down by sacred tradition.
Eastern Orthodoxy developed in the Greek-speaking Eastern part of the Roman Empire, continuing later in the Byzantine Empire.
The majority of Eastern Orthodox Christians live in Eastern Europe, Greece, and the Caucasus, with smaller communities in the former Byzantine regions of the eastern Mediterranean, Africa, and to a decreasing degree also in the Middle East due to persecution. There are also many in other parts of the world, formed through diaspora, conversions, and missionary activity.
The Orthodox Church now is the 2nd-largest Christian Church, with over 250 million members.
The Catholic Church is one of the oldest religious institutions in the world. Headed by the Bishop of Rome, known as the Pope, the church’s doctrines are summarised in the Nicene Creed. Its central administration, the Holy See, is in the Vatican City, enclaved within Rome (Italy).
The Catholic Church teaches that it is the One, Holy, Catholic and Apostolic church founded by Jesus Christ, that its bishops are the successors of Christ’s apostles, and that the Pope is the successor to Saint Peter to whom primacy was conferred by Jesus Christ.
The Catholic Church is the largest Christian church, with more than 1.29 billion members worldwide.
Bogomils were founded in 10th century in Bulgaria by a priest Bogomil. The Bogomils’ central teaching, based on a dualistic cosmology, was that the visible, material world was created by the devil. They denied the doctrine of the incarnation and rejected the Christian conception of matter as a vehicle of grace.
They wanted one independent Slavic church with teachings of early Christianity. Bogomils were common in Bosnia, Bulgaria, and Dalmatia (Region in Croatia).
