She was a pagan maiden living in Sicily with her mother (also named Euthalia) and her brother Sermilianus. When Euthalia’s mother became ill with an issue of blood, the holy martyrs Alphius, Philadelphus and Cyrinus (May 10) appeared to her in a dream and told her that she would only be healed if she were baptised in the name of the Lord Jesus Christ. Heeding the dream, she believed, was baptized, and was healed. Her daughter Euthalia, seeing this wonder, was also baptised. Sermilianus, despising and hating the Christian faith, first mocked his mother and sister for their conversion, then threatened them. The mother fled the house in fear. Euthalia remained, saying to her brother ‘I am a Christian, and have no fear of death.’ The cruel Sermilianus persecuted her more and more harshly until finally, enraged by the futility of his threats, he beheaded his own sister by his own hand, unknowingly procuring for her a crown of eternal glory. “And thus in this example were fulfilled the words of Christ that He was bringing a sword among men which would divide those of one blood but not those of one faith (Matt. 10:34-35).” (Prologue)
