A manuscript of the gospels which once belonged to the Church of St. Kerykos and St. Jolitta at Koridethi in the Caucasus Mountains near the Caspian Sea. It is written in a rough uncial hand by a scribe who knew little or no Greek. Edited in modern times by G. Beermann and C.R. Gregory, who dated it in the ninth century, it contains a Byzantine-type text in Matthew, Luke, and John, but one akin to the type of text used by Origen and Eusebius at Caesarea in Mark. The MS is identified by the Greek letter theta or the number 038 in critical texts of the NT. It is now located in the museum at Tiflis, the capital of the Soviet Socialist Republic of Georgia.
