Acarius was a 7th-century monk from the Abbey of Luxeuil who eventually served as the Bishop of Doornik and Noyon. Born into a noble Burgundian family, he studied under Abbot Eustace and was a contemporary of Audomar. As a prominent advisor to King Clothar II, he played a significant role in expanding Christian influence throughout Belgic Gaul. He was known for his support of missionaries and his dedication to the welfare of the impoverished.
Life and work
During his episcopate, Acarius focused on charitable works, specifically tending to the poor and those suffering from various afflictions. He also contributed to the religious landscape by establishing several monasteries. He used his political influence to assist fellow clergy, such as recommending Audomar for a bishopric and supporting the missionary Amandus, even after the latter faced banishment by King Dagobert I.
Veneration
Following his death, Acarius was recognized as a saint. His remains were originally housed at Jumièges Abbey before being relocated to Haspres Abbey to protect them from Viking raids. He remains the patron of Haspres, where he is remembered through local traditions. Devotees sometimes invoke his name to help mitigate difficult or cantankerous moods.
