Roman Catholic Church
Communion · no year is recorded
The Western church, in communion with the see of Rome, whose succession this dataset holds as the Rome line. It keeps the Roman Rite and computes Pascha on the Western reckoning.
No year is recorded anywhere. The era is fixed by Leo IX (1054), whom the source names — that is not a founding date.
