Emmanuel of Sirmium

Holy Martyr Emmanuel of Sirmium was arrested and put to death at Sirmium in Pannonia (today in Serbia) in the year 304, together with forty-⁠two other martyrs, among them Quadratus and Theodosius, in the persecution of Diocletian. He is commemorated on 26 March (new style).

The surviving sources are brief and say no more about his life. What remains is the memory of a large group of Christians of the city of Sirmium who confessed Christ in the hardest persecution of the early centuries.
