Career
Being of noble birth, he was brought up in the royal court of Guntram, but wanted to become a priest, and was ordained by Saint Syagrius of Autun, and eventually was made Bishop of Auxerre. His administration is noted for certain important disciplinary measures that throw light on the religious and moral life of the Merovingian times. He caused solemn litanies to be said daily in the chief centers of population, by rotation, and on the first day of each month in the larger towns and monasteries.
He enforced a regular daily attendance at the Divine Office on the part both of regular and secular clergy.
Aunarius was buried at Auxerre, where he has always been held in veneration. A portion, however, was placed in the hollow pillar of a crypt, and saved.
His feast is celebrated 25 September.
