Ambrosius of Georgia, born Besarion Khelaia in Martvili, was a prominent Eastern Orthodox theologian and religious leader. After graduating from the Tiflis Theological Seminary in 1885, he served as a priest in Abkhazia and wrote a thesis concerning the relationship between Christianity and Islam. He became a central figure in the movement for Georgian autocephaly and later served as the Metropolitan of Chkondidi. In 1921, he was elected Catholicos-Patriarch of All Georgia, leading the church during a period of intense political transition.
