Church of the East

Communion · no year is recorded

The church beyond the Roman frontier, seated at Seleucia-Ctesiphon, whose catholicoi this dataset holds as the Seleucia line and whose synods from 410 onward are collected in the Synodicon Orientale. It keeps the East Syriac Rite and names most of its days by the Sunday of their season rather than by a date.

No year is recorded anywhere. The era is fixed by Ahha (415), whom the source names — that is not a founding date.
