Leo Tolstoy’s novella Father Sergius follows the spiritual transformation of Prince Stepan Kasatsky. Tolstoy wrote the work in the late nineteenth century, but it was published posthumously in 1911.
Kasatsky begins as an ambitious aristocratic officer. After a personal crisis, he enters religious life and becomes Father Sergius. His reputation for holiness grows, yet Tolstoy presents fame and public admiration as dangers that can distort genuine spiritual purpose.
The story examines pride, sexuality, institutional religion, and the difference between outward sanctity and inner moral change. Kasatsky’s journey is not a simple rise from sin to perfection; it is a series of reversals in which he recognizes the weakness of relying on status, discipline, or the approval of others.
Father Sergius is sometimes grouped with Tolstoy’s moral and religious fiction rather than his major novels. Its posthumous publication means readers should not assign it a normal Tolstoy publication date from the author’s lifetime.
