On January 15, 2022, the rite of naming the bishop took place at the Uspenski Cathedral.

On January 16, 2022, his episcopal consecration took place in the Uspenski Cathedral. The consecration was performed by Archbishop Leo of Helsinki and all Finland, Metropolitan Arseni (Heikkinen) of Kuopio and Metropolitan Elia of Oulu. Bishop Nazary of Kronstadt was present at the service as an official representative of the Russian Orthodox Church.

On November 23, 2021, the Bishops' Council nominated Sergei as the only candidate for election to the vicar bishop's position of the Helsinki Diocese. On November 25, in the vote of the members of the Council of the Orthodox Church in the New Valaam Monastery, he was elected for ordination as Bishop of Hamina, vicar bishop of the Helsinki Diocese.

On November 8, 2012, the Deputy Chancellor of Justice of Finland, Mikko Puumalainen, reprimanded Archbishop Leo: according to the law, he did not have the right to single-handedly dismiss the hegumen of the Valaam Monastery, whose post is for life.

On November 22, 2012, he was reinstated by Archbishop Leo as hegumen of the New Valaam Monastery.

On November 9, 2011, by decree of Archbishop Leo of Karelia and all Finland, he was relieved of his post as hegumen due to the financial condition of the monastery, as well as due to disagreements between the rector and commercial director of the monastery, Veikko Halonen.

In 1997 he was elected and approved as the hegumen of the New Valaam Monastery. He heads the Society of Friends of Valaam (Fin. Valamon Ystävät ry) and the Orthodox Brotherhood (Fin. Ortodoksinen Veljestö ry).

In July 1990 he entered the brotherhood of the New Valaam Monastery in Heinävesi, where in December 1991 he was tonsured a rassophore by Archimandrite Panteleimon (Sarho), and in March 1992 he became a monk with the name Sergius. In 1992 Bishop Ambrosius (Jääskeläinen) of Joensuu ordained him as a hierodeacon, and in 1995 Archbishop John (Rinne) of Finland ordained him a hieromonk.

In 1984 he graduated from the Pieksämäki Gymnasium and entered the Kuopio Theological Seminary, from which he graduated in 1988 (the last year of his stay in Kuopio). From 1988 to 1989 he served in the Finnish army, during which time he received the training of a military pastor. Then he continued his studies at the Orthodox Theological Faculty of the University of Joensuu, from which he graduated in 1990 as an Orthodox teacher.

His grandmother and grandfather bore the surname Gordeyev, which in the 1920s they changed to Finnish in the wake of de-Russification. He was baptized into Orthodoxy at the age of one month. At the age of three, he lost his father. The Orthodox activist Eino Hartikainen, who lived in their village, and hieromonk Sergei (Leimu), a resident of the New Valaam Monastery, had a great influence on the upbringing of the boy. He visited the church of the Theotokos of Tikhvin in his native village.
