Dorotheos and Eusebia, a devout, aging Christian couple who lived in Anatolia, had no children. After many years, their fervent prayers for a child were answered, and they were blessed with a daughter, whom they named Kyriake ('Sunday' in Greek) because she was born on the Lord's day. The child grew up beautiful in body and soul and, though she had many suitors, chose to consecrate herself entirely to God and remain single. One of her suitors, angered at her refusal, denounced her and her parents to the Emperor Diocletian. Dorotheos and Eusebia were subjected to cruel tortures, then sent into exile, where they died under further torture. Kyriake was sent to Maximian, Diocletian's son-in-law, for trial. By his orders, she was subjected to a horrifying series of torments; but Christ Himself appeared to her in prison, healing and comforting her. Many pagans came to believe in Christ when they saw her miraculously saved from death by fire or from wild beasts; all of these were beheaded. Kyriake told Apollonius, the general who supervised her tortures: 'There is no way that you can turn me from my faith. Throw me into the fire — I have the example of the Three Children. Throw me to the wild beasts — I have the example of Daniel. Throw me into the sea — I have the example of Jonah the Prophet. Put me to the sword — I will remember the honored Forerunner. For me, to die is life in Christ.' Apollonius then ordered that she be beheaded. At the place of execution, she raised her hands in prayer and gave up her soul to God before the executioner could take her life.

Note: St Kyriake is also known as Dominica or Nedelja, Latin and Slavonic words for 'Sunday'.
