In the times prior to theological disputes that arose between 9th and 11 century, Byzantine Rite churches of the East and Latin Rite churches of the West were in full communion, confessing the same Orthodox, Catholic Christian faith. In the East, the Byzantine Rite was the predominant liturgical rite. In the West, the Latin Rite was the dominant rite. In the time of the final East–West Schism of 1054, most of the Churches that remained in communion with four Eastern Patriarchates used the Byzantine Rite, though there were still regions where other liturgies, including the Roman Rite, were used. One of such regions was Byzantine (southern) Italy.
