The Holy Protomartyr Stephen appeared to the Priest Lucian to reveal the location of his relics which had been lost. First, they were translated to the Church of Holy Sion in Jerusalem in the year 415 with many miracles attending the event. Later, they were translated to the Imperial city of Constantinople, once again, accompanied by signs and wonders. One such event was the casting out of some demons that were hiding amongst the waves of the sea in Chalcedon. When the relics passed by, the demons cried out that they were being burned by the fire of the uncreated light which radiated out from the holy relics.
Hymnography
With the light of the Spirit, thou shonest brilliantly, and with the only true wisdom, thou wast exalted, O Saint; wherefore thou didst drive away the darkness of the Jews, and didst hurl down our common foe as an athlete in the fray; hence, thou art the crown of Martyrs. Now intercede with the Lord God that He may show His mercy to our souls.
(Sessional Hymn, First Troparion; Orthros Canon)
Thou hast appeared unto the world like a beautiful daybreak, O glorious Stephen, driving off the gloom, chasing away demonic specters, and healing the sufferings of the sick and the sores of spiritual maladies, O inspired of God.
(Ode Five, Second Troparion; Orthros Canon)
