St. Naum is called upon to intercede with the Lord for people with mental disorders.
St. Naum of Ohrid (or Preslav) followed in the footsteps of St. Cyril and Methodius, missionaries to the Slavic lands, who translated liturgical texts from Greek into the language of the people, Slavonic. As they lived before the schism with Rome, St. Naum accompanied St. Cyril and Methodius to Rome, where God worked many miracles through them, so that the Pope came to see their translation work as a work of God. On their way back to their mission field, the Slavic lands, they traveled through Germany, where they opposed a number of heresies, and were tortured and imprisoned. Freed through an earthquake from God, they proceeded to Bulgaria, where St. Naum traveled about with fellow disciple St. Clement distributing the Bulgarian translation of the Holy Scriptures and preaching the Way of Christ. His feastday is December 23.
There is a Monastery on the shore of Lake Ohrid named after him: St. Naum Monastery on Ohrid Lake, Macedonia
