Ethiopian monarchy embraced Christianity at its very early stages, and it became the state religion in the 4th century. Already in the 7th century there was Muslim influence. Tensions and conflict have been recurrent between the Christian and Muslim communities. The Ethiopian Orthodox Tewahedo Church is one of the churches that does not accept the decisions of the Council of Chalcedon on the nature of Christ. It was the state church under the monarchy but has lost this position. Catholic presence goes back to the 16th century, and Protestant missions arrived in the 20th century. The largest non-Orthodox church is the World of Life Church (Evangelical), followed by the Mekane Yesus Church (Lutheran and Presbyterian). There are also two large Pentecostal churches. Most of these churches belong to the Ethiopian Evangelical Churches Fellowship, which is affiliated with the WEA.
