Scholar and Bishop
Kirion was known as a learned man and a productive church historian. According to the sources, he authored more than forty monographs on Georgian Church history and Christian culture, and in 1898 he published a description of the historical monuments of the Liakhvi Gorge. He is also reported to have collaborated with the linguist Grigol Qipshidze on a history of Georgian philology, and to have undertaken archaeological work that recovered older ecclesiastical treasures.
His episcopal career took him through a series of sees. He was consecrated Bishop of Alaverdi in August 1898 and installed as Bishop of Gori in 1901, after which he was reassigned by the Russian church authorities to dioceses outside Georgia, including Cherson, Orel, Sokhumi, and Kovno, and was elevated to Archbishop of Polotsk and Vitebsk by 1915. The sources connect him with the movement to restore the autocephaly of the Georgian Church, recording that he presented arguments in its favor to a Russian commission in 1905.
