Council of Capharthutha

The Council of Capharthutha (also Kafartut or Kafr Tut) was a synod of the Syriac Orthodox Church held in February 869 AD under Patriarch John IV of Antioch. It was called to resolve the differences between the Patriarch of Antioch and the Maphrian of the East over their ecclesiastical jurisdiction in Mesopotamia and Persia. It aimed to regulate mutual relations and to resolve some difficulties that were frequently arising between two centers.
Canons.
The assembly codified eight canons preserved in Bar Hebraeus' 13th-century nomocanon, the "Kthobo d-Hudoye" (Book of Guides):
Maphrian.
The word "Maphrian" is an analogue of the Greek (), meaning 'concerning the whole', 'universal' or 'general'. It was a title that existed in the Roman Empire where a government representative who was in charge of a large area was called a . The churches later started to use this term for their chief bishops.
"Maphriyono" ('Maphrian') is derived from the Syriac word , 'to make fruitful', or 'one who gives fecundity'. This title be used exclusively for the head of the Syriac Orthodox Church in the East. From the mid 13th century onwards, a few occupants of the Maphrianate were also titled "catholicos", but the title never came into extensive usage.
According to one of the most famous Maphriyans, Mar Gregorios Bar Ebraya (Bar Hebraeus), the Apostle Thomas was the first in the Apostolic succession of the East. Bar Ebraya did not believe that the Eastern Church was an integral part of the Antiochian Church, due to the historical context of the time in which he lived. He did, however, vigorously defend his rights, as dictated by the church canons.
