Just of Lyon was a 4th-century bishop who served as the 13th leader of the see in Lyon, Gaul. Born into an aristocratic family in Tournon-sur-Rhône, he was known for his merciful nature and scholarly intellect. After participating in significant ecclesiastical gatherings such as the Council of Valence and the Council of Aquileia, he resigned his position following a tragic incident involving a fugitive seeking sanctuary. Seeking a life of penance, he traveled to Egypt to live as a hermit among the monks of Scetes.
Life and ministry
As bishop, Justus participated in important councils to address religious discipline and the rejection of Arianism. Following a controversial event where a man he had granted sanctuary to was killed by a mob, Justus felt personally responsible for the outcome. This guilt led him to abandon his episcopal duties and seek asceticism in the Libyan Desert, where he joined the community led by Macarius of Egypt.
Veneration and legacy
He died in Wadi El Natrun around 390, and his remains were eventually returned to Lyon. He is honored as a saint by both Catholic and Orthodox traditions, with his primary feast day observed on 2 September. His memory is preserved in the Saint-Just district of Lyon, which grew around the sites dedicated to his relics.
