Early Life and Monastic Formation
Goderdzi Urgebadze was born in Tbilisi on 26 August 1929. His father, Vasili, died when the boy was about two years old; his mother, Varvara, by tradition later became a nun under the name Anna. Accounts relate that he was drawn to Christ from a young age — by some accounts purchasing a Gospel as a child after first hearing the name of God — and that his devotion set him at odds with his household, so that he left home while still a boy.
He received monastic tonsure on 23 February 1955 at Motsameta Monastery near Kutaisi, taking the name Gabriel in honor of Gabriel the Iberian. He was ordained hieromonk shortly afterward. He served in Tbilisi at Sioni Cathedral and at Betania (Bethany) Monastery, where, according to the tradition, his spiritual fathers were the confessors later glorified as saints of the Georgian Church.
