I thought the Sarum Rite went way back further than that. Like at least the 8th or 9th century.
AnAmericanMother:
I always thought it [Sarum Rite] went back to the early 13th century, which is still some 300 plus years before the Council of Trent was called in 1537.
AnAmericanMother:
I was somewhat off with my dates, at Newadvent.org, it states that the Sarum Rite was in place as early as 1078, which puts it in the 11th century. From that article, it is also clear that the English were celebrating the Liturgy consistent with the Church of Rome in the 8th century, as you note.
However, what is unclear is whether that was the Sarum-Rite or some other form of the Roman Rite being celebrated in the 8th century.
