An example prayer from the web site of the Greek Orthodox Archdiocese of America:
Spyridon the Wonderworker of Trymithous
December 12
Apolytikion in the First Tone
O Father, God-bearer, Spyridon, you were proven a champion and Wonder Worker of the First Ecumenical Council. You spoke to the girl in the grave and turned the serpent to gold. And, when chanting your prayers, most sacred One, angels ministered with you. Glory to Him who glorified you; glory to Him who crowned you; glory to Him who, through you, works healing for all.
Kontakion in the Second Tone
Wounded by your love for Christ, O holy One, your mind given wings by the radiance of the Spirit, you put the practice of theory into deeds, becoming a sacred altar, O Chosen by God, and praying for the divine illumination of all.

A native of Cyprus, St. Spyridon was a sheep farmer who had been tortured during the persecutions of Diocletian. Famed for this knowledge of the Bible, Spyridon was married and had children at the time of his elevation to the see of Tremithius. Legends say that he attended the Council of Nicaea (321), but his name is not on the official list of attending bishops. He attended the Council of Sardica (c. 343), at which Constantius requested the condemnation of Athanasius of Alexandria. Spyridon died c. 348.
