The four historical patriarchates of the Eastern Orthodox Church–Constantinople, Alexandria, Antioch, and Jerusalem–are all located in North Africa and West Asia. Eastern Orthodox today view themselves in continuity with the first apostles through the handing on of tradition. Important elements of Eastern Orthodox practice include the veneration of the saints and of icons; the daily, weekly, and annual cycles of the liturgy; and the mystery of the Eucharist. Historically, the Orthodox Church of Antioch became culturally Arabized through contact with Islam. The twentieth century has seen several Eastern Orthodox renewal movements in this region, including the Orthodox Youth Movement in Syria and Lebanon, which was founded in 1942, and the monastic renewal in the Coptic Orthodox church in the 1960s.
