The overwhelming majority of Eritrean Christians are Orthodox (Oriental). Before Eritrea's independence, they came under the Ethiopian Orthodox Church. The Eritrean Orthodox Tewahedo Church became autocephalous in 1994, with the help of the Coptic Orthodox Church, and joined the WCC in 2003. Catholic and Protestant presence dates from the 19th and 20th century. More recently, some Pentecostal and Evangelical groups have entered the country.
