The origins of Russian spirituality lie both in the Ancient Fathers and from the influence of Byzantine traditions. The distinctive character of Russian spirituality may be in the way the living tradition of popular piety intersects with the rituals of the Church and the teaching role of the Russian startzy (spiritual directors).
