According to the writings by Saint Eucherius, bishop of Lyon (434), Candidus was a commander of the Theban Legion, which was made up of Christians from Egypt. The Golden Legend states, “And the nobleman, Maurice, was duke of this holy legion, and those who governed beneath him, were called Candidus, Innocent, Exsuperius, Victor and Constantine; they were all captains”. Candidus was called Maurizio’s senator militum or staff officer. He opposed Maximian, who had ordered the persecution of local Christians in his name, stating that “we are your soldiers, but we are also servants of the true God. We cannot renounce Him who is our Creator and Master, and also yours even though you reject Him”. Candidus, with Maurice, and other staff officers and 6,600 soldiers, is said to have been martyred in the Swiss city of Saint Maurice-en-Valais, then called Agaunum. His feast day is 22 September. Candidus’ relics were stored in a 6th-century reliquary at the Abbaye de Saint-Maurice d’Agaune. His skeleton is kept in a display case in the collegiate church of Fucecchio.
