Biography

Saint Caius of Nicomedia, also known as Saint Gaius, was one of the Christian soldiers who endured great persecution and martyrdom during the reign of Emperor Diocletian. Born in Nicomedia, a city located in modern-day Turkey, Caius lived during a time when Christianity was heavily suppressed. Caius, along with fourteen other brave soldiers, was known for his unwavering faith and commitment to the teachings of Jesus Christ. These soldiers, who became collectively known as the "Fifteen Martyrs of Nicomedia," were steadfast in their refusal to renounce their Christian beliefs, even in the face of severe torture and imminent death. During the Diocletianic Persecution, Emperor Diocletian sought to eradicate Christianity from the Roman Empire. The Fifteen Martyrs of Nicomedia, including Caius, were subjected to various forms of cruelty and torture.
