Missionary Teacher in Alaska
In 1902 Samoilovich took up a teaching post at the two-year school in Unalaska, in the Aleutian Islands, then part of the North American diocese of the Russian Church. By 1905 he was teaching at Sitka, where he was tonsured into the monastic mantiya by Bishop Innocent (Pustynsky) and, about a month later, ordained hieromonk. He went on to serve as rector of a local mission and to teach at the Sitka Theological Seminary, working as an associate of Archbishop Tikhon, the future Patriarch of Moscow.
Sources record that the harsh northern climate told upon his health, and after 1908 he returned to Russia. There he filled a sequence of offices — diocesan missionary, seminary confessor, and monastery vicar — including the post of vicar of the Uglich Protection Monastery from 1915, the see with which his name would afterward be joined.
