On [[October 1]], 1825, Jacob was [[tonsure]]d a sub-deacon. He married Anna Simeonovna, a Russian woman perhaps of a Creole background as was he, and then in 1826 he graduated from the seminary with certificates in history and theology. With graduation he was ordained a [[deacon]] on [[October 31]], 1826 and assigned to the Holy Trinity-St. Peter Church in Irkutsk. Two years later, [[Archbishop]] Michael ordained Jacob to the holy [[priest]]hood on [[March 4]], 1828. Archbishop Michael had earlier ordained John Veniaminov (St. Innocent) to the priesthood. With his elevation to the priesthood, Father Jacob began to yearn to return to his native Alaska to preach the Word of God.
Upon departing, Archbishop Michael gave Father Jacob two [[antimension|antimensia]], one for use in the new church that Father Jacob planned to built on Atka, and the other for use in Father Jacob's missionary travels. After a [[molieben]], Father Jacob and his party set off for Alaska on [[May 1]], 1828. The travelers included Father Jacob, Anna his wife, and his father Yegor who had been tonsured reader for the new Atka Church. This journey, which was always hard, took over year to complete, which was completed on [[June 15]], 1829.
