Ephraim II (Georgian: ეფრემ II, Eprem; 19 October 1896 – 7 April 1972) was a Catholicos-Patriarch of All Georgia from 1960 until his death. His full title was His Holiness and Beatitude, Archbishop of Mtskheta-Tbilisi and Catholicos-Patriarch of All Georgia.
Born as Grigol Sidamonidze, the future prelate graduated from the Tiflis Theological Seminary in 1918 and from the Tbilisi State University with a degree in philosophy in 1925. He became a monk in 1922. At various times, from 1927 to 1960, he served as bishop of Nikortsminda, bishop of Gelati and Kutaisi, and metropolitan of Batumi-Shemokmedi and Chkondidi. After the death of Melchizedek III in 1960, Ephraim was elected to the office of Catholicos-Patriarch of Georgia. During his tenure, Ephraim tried to avoid confrontation with the Soviet government, but produced a series of sermons, appealing to Georgian patriotism, for which he gained popularity.[1]
