Alexander Ivanovich Brilliantov was born into a priestly family in the Kirillovsky district of Siberia. He pursued his education at the Kirillov Spiritual School (1877-1881), Novgorod Seminary (1881-1887), and Saint Petersburg Spiritual Academy (1887-1891).
Academic Career
Following his ordination as a priest, Brilliantov served as a teacher and missionary in the Tula Eparchy. In 1898, he earned a Master's degree in Theology from Saint Petersburg Spiritual Academy with a thesis on the influence of Eastern theology on Western thought.
In 1900, he became an associate professor at the Department of General Church History at Saint Petersburg Spiritual Academy. He was promoted to extraordinary professor in 1904 and ordinary professor in 1914. He played an active role in church commissions and collaborated with the Russian Archaeological Institute in Constantinople.
Brilliantov was a member of the Preconciliar Assembly and Council of the Russian Orthodox Church (1917-1918). He was considered as a candidate for the post of ruling bishop of the Petrograd Eparchy in 1917.
