Sixtus of Reims was an early Christian presbyter who served as the first bishop of Reims. Sent from Rome to Gaul to aid in the conversion of the region, he is credited with establishing the Christian sees of Reims and Soissons alongside his companion, Sinicius. While some traditions suggest he was a disciple of Saint Peter, historical accounts from the 9th century indicate he was dispatched by Pope Sixtus II to assist in the Christianization of the area.
Life and ministry

During his mission in Gaul, Sixtus worked to build the foundations of the local church. He is recognized for founding the ecclesiastical seats in both Reims and Soissons. His companion, Sinicius, eventually succeeded him in the leadership of Reims. Although he lived during a period of intense persecution, historical sources suggest that he did not die as a martyr.
Veneration
He is remembered as a saint within the Catholic tradition. His feast day is observed annually on September 1. His legacy remains tied to the early establishment of the church in the Reims region, where he is honored as a foundational figure for the local Christian community.
