The Church of the East is the faith of the Kereyit by tradition: they are the Christian people of the steppe, and the Naiman, the Ongud and some Merkit and Onggirat are Christian in part beside them.
In 1200 the church is a travelling clergy attached to the khan's ordu and to the camps of the nobles, with Syriac books and vessels, probably a tent church at the ordu (the 1009 mission carried a tent for the altar; none is described for 1200), and Christian families among the clans. It owns no land and no town. It lives on the khan's protection. Christians and shamans share the same camps and the same war; no quarrel between them is recorded.
Toghrul's own faith is presumed, not shown. The story that he is Prester John, the Christian king of the East, is a European idea of later decades and has not begun.
Who holds it
- Title
- A clergy of priests and deacons attached to the khan's ordu and the camps of the nobles; no bishop or metropolitan of the Kereyit is named in any source reached
- Since
- The faith is dated by tradition to about 1009
- Born
- not known
- Family
- The ruling house carries Christian names in Rashid: Marghuz (Marcus) Buyiruq Khan, Toghrul's grandfather, and Qurjaqus (Cyriacus) Buyiruq Khan, his father. Toghrul's niece Sorqaqtani, born in the 1190s on the usual dating and so a child in 1200, is a Christian in later life.
- Confidence
- medium for the church among the people; low for persons and for the year
Bar Hebraeus preserves the letter in which Abdisho, metropolitan of Merv, told the Patriarch that a king of the Kereyit, lost in a snowstorm, had been guided by a saint in a vision and had asked for Christian teachers; the Patriarch sent priests and deacons and a tent for the altar. The year is given as about 1009. This session could not open Bar Hebraeus; the account is from memory. The English Wikipedia article on Toghrul says the Keraites took the Church of the East early in the 11th century.
Overlord
The Patriarch (Catholicos) of the East at Baghdad, Yahballaha II (1190 to 1222). His hold on a church so far away is nominal, and the nearest metropolitan see is not known.
What it holds
- No estates, villages or revenue attested
- A tent altar, books and vessels at the ordu (inferred from the 1009 mission)
- The offerings and protection of the khan and the nobles
- Baptised families among the clans (no count, no list)
How it was acquired
Tradition: the Kereyit were baptised about 1009 after the letter of Abdisho of Merv.
Allies and rivals
Patron: the Kereyit khan and nobles. Of the same faith in part: the Naiman (the Kereyit's enemies, so the faith is no bond), the Ongud who guard the Jin march, some Merkit and Onggirat. Distant brethren: the Church of the East in the Tarim and at Qocho (tar sheet). The shamans share the camps; no open quarrel is recorded.
How things stand that morning
No bishop is named in any source reached. A priesthood of unknown size serves the ordu and the clans. The royal house is Christian in name by descent and Sorqaqtani is a Christian child of the family. The Patriarch's authority is a name. Priests, scribes and merchants who pass between the Kereyit court, the Ongud and the Tarim cities are the church's link to the world (see Merchants at the ordu).
Wealth
Offerings and protection from the khan and the nobles; books, vessels and a tent for the altar. No land.
Threats
- The khan's fall: a church that lives on the khan's tent has no ground of its own
- Few priests and no known bishop (inference)
- The loss of the khan's protection if Senggum and the nobles turn on Temujin and the Mongols answer
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- 1203After the fall of the Kereyit, Kereyit Christian women marry into the Mongol house, Sorqaqtani among them, who will be the mother of khans; the church survives under Mongol protection (one line; after the opening date).Depends on: The war of 1203. Stopped by: A different end to it.
Places of note
- Tent church at the khan's winter ordu (inferred): Where the Kereyit church would stand in winter: a tent beside the khan's; not described for 1200.
Where the sources disagree
- The brief and the assignment speak of Toghrul's 'Christian household'. The English Wikipedia article on Toghrul says there is no credible proof that he was Christian himself, because the Mongolian sources say nothing of his religion; it lists his religion as 'Nestorian Christian (presumed)'. This record keeps the church of the people and the Christian names of his house, and treats his own faith as presumed.
- The assignment asks for 'their bishops'. No bishop of the Kereyit is named in any source reached.
- The identification of Toghrul with Prester John is of the 1250s to 1290s (Rubruck and Marco Polo, who speak of the Kereyit king as 'Unc' or 'Unc Khan') and has not happened on 1 January 1200.
Evidence: The conversion tradition and the Christian names are in Bar Hebraeus and Rashid, from memory. A tent church and priests at Toghrul's ordu in 1200, and the royal women's faith, are inferred from the people's faith and from later lives.
On the map: No ground; a point at the khan's winter ordu. The faith ran through the clans across the whole Kereyit range.
