first country to adopt christianity as state religion
Armenians Most Armenians adhere to the Armenian Apostolic Church, a non-Chalcedonian church, which is also the world's oldest national church. Christianity began to spread in Armenia soon after Jesus' death, due to the efforts of two of his apostles, St. Thaddeus and St. Bartholomew.[26] In the early 4th century, the Kingdom of Armenia became the first state to adopt Christianity as a state religion.[27]
Religion in Africa Christianity is now one of the most widely practiced religions in Africa along with Islam and is the largest religion in Sub-Saharan Africa. Most adherents outside Egypt, Ethiopia and Eritrea are Roman Catholic or Protestant.[citation needed] Several syncretistic and messianic sects have formed throughout much of the continent, including the Nazareth Baptist Church in South Africa and the Aladura churches in Nigeria.There is also fairly widespread populations of Seventh-day Adventists and Jehovah's Witnesses. The oldest Christian denominations in Africa are the Coptic church in Egypt and the Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church, all Oriental Orthodox, which rose to prominence in the fourth century AD after King Ezana the Great made Ethiopia one of the first Christian nations.[22]
