Saint Rufinien was a 5th-century bishop who served the diocese of Bayeux. Born into the influential Rufini family in Rome, his exact origins and the specific timing of his arrival in Normandy remain uncertain. During his tenure as a prelate, he played a significant role in spreading Christianity throughout his region. He is notably remembered for ordaining Saint Lupa as a deacon, an event that led a contemporary named Stephen to predict Lupa would eventually succeed him as bishop.
