The manner of regulating the details of the Roman Liturgy that obtained in Pre-Reformation times in the south of england and in parts of Scotland and Ireland. Anglo-Saxon Christians knew only the Roman Liturgy, as we learn from the Synod of Clovesho (747). Saint Osmund, a Norman Bishop of Salisbury, compiled a Missal, Breviary, and Ritual, revising the Anglo-Saxon readings of the Roman Rite to incorporate certain Norman liturgical traditions. The Roman Rite itself has always permitted laudable local customs, and the adoption of the Sarum Service Book did not mean the rejecting of existing ceremonial usages in favor of those in vogue at Salisbur, but only a fitting thereof into the framework outlined in the Sarum Missal, Breviary, and other liturgical manuals. The Sarum Rite, in the main, represents the Roman Rite as carried out in the 11th century, and the reforms of the popes, notably the Franciscan, revision in the 13th century, very slowly found their way into the service books of the Church in Britain.
