Actually, John, you can get an argument about whether the Maronites are Orientals. Strictly speaking, as there is no Oriental Orthodox counterpart to the Maronites, they are not and many place them and the Assyrians-Chaldeans as existing out there in two small categories each their own - neither Eastern nor Oriental. Others will tell you that the Maronites, being of similar liturgical descent as the Antiochene (Syriac) Churches, which are Oriental, should be classed as such.
Regardless, among the Orientals, you'll find considerably more differences than you will among the Eastern-Byzantine Churches - where language is the most notable.
"One day all our ethnic traits ... will have disappeared. Time itself is seeing to this. And so we can not think of our communities as ethnic parishes, ... unless we wish to assure the death of our community."
