Shahdost

Shahdost, also Sadoc, Sadoth () () was Bishop of Seleucia-Ctesiphon and primate of the Church of the East from 341 to 343 who resided in the Sasanian Empire. He was martyred during the great persecution of Shapur II. Like several other early bishops of Seleucia-Ctesiphon, he is included in the traditional list of patriarchs of the Church of the East. He is considered a saint in several Eastern Christian denominations.

== Sources == Brief accounts of Shadost's episcopate and martyrdom are given in the Ecclesiastical Chronicle of the Jacobite writer Bar Hebraeus (floruit 1280) and in the ecclesiastical histories of the Nestorian writers Mari (twelfth-century), (fourteenth-century) and Sliba (fourteenth-century). A more substantial account of his patriarchate is also given in the Chronicle of Seert. In all these accounts he is anachronistically called 'catholicus' or 'patriarch', a term that was only applied to the primates of the Church of the East in the fifth century.
