Audomar, also known as Omer, was a 7th-century Benedictine monk and the Catholic bishop of Thérouanne. Born into a noble family in the Frankish realm of Neustria around the turn of the 7th century, he studied the Scriptures at the abbey of Luxeuil. He was appointed to lead the diocese of Thérouanne in 637, where he worked to revitalize the Christian faith among the Morini people through missionary efforts and the establishment of new religious centers.
Life and work
After his education at Luxeuil, Audomar was consecrated bishop in 637. He focused on spreading Christianity by sending missionaries to various estates, including Sithiu. In this region, he founded the Abbey of Saint Peter, which became a significant center for religious learning. He also established the Church of Our Lady of Sithiu, providing a monastic community with a dedicated place for worship and burial.
Veneration
The saint is commemorated by both the Catholic and Eastern Orthodox churches. His feast day is observed on 9 September. While his exact burial site remains uncertain, he is likely interred in the church that became Saint-Omer Cathedral, where a 13th-century cenotaph honors his memory. The town of Saint-Omer in northern France takes its name from him.
