Life and ministry
Before his ordination, Gregory Averin trained at a teachers' seminary and worked in a church-parish school in Kologriv. He was ordained a celibate priest in 1921 and served in the Kostroma area and afterward at the church in the village of Simeon, Puchezh district, in the Ivanovo region.
Like many clergy of his generation, his ministry unfolded under mounting state hostility to the Church. He was first arrested as early as 1918 amid the unrest of the civil-war years and released, but from 1930 onward he was repeatedly imprisoned.
