The Melkite Greek Catholic Church uses the Byzantine rite (tradition of Saints John Chrysostom and Basil). The liturgical language is Arabic (and sometimes Greek). Here (no embedding) is a chant performed at the start of Holy Communion, sung in the Saint Paul Basilica, the Melkite cathedral in the Lebanese mountain village of Harissa. You’ll hear the word Allah.
Melkite comes from the Syriac word malkoyo (ܡܠܟܝܐ in the Syriac alphabet) and the Arabic malakī (ملكي), meaning royal, and by extension, imperial (ie Byzantine).
Nearby is the Marian shrine Notre Dame du Liban, visited by all Christian denominations. Christians, Druze and Muslims all have a devotion to Mary.
Here, courtesy of KTO, the French-language television channel of the Archbishop of Paris, is Benedict XVI at Harissa in September 2012; he reads an apostolic exhortation, Ecclesia in Medio Oriente, in French (it came out of his 2010 Special Synod on the Middle East), and signs it:
He also met the Syriac Maronite Patriarchate, Armenian Catholic Patriarchate, Syro-Catholic Patriarchate (Syriac Catholic) and others. Maronites, Armenians and Syrians are the three Catholic churches headquartered in Lebanon.
