Marcellinus of Gaul was a 4th-century North African cleric who served as the first bishop of Embrun. Born in Africa Proconsularis, he traveled to Rome alongside fellow bishops Vincent and Domnin to participate in a 313 synod regarding the Donatist movement. Following a mission from Pope Miltiades, he traveled through the Italian side of the Alps to preach the gospel. After preaching toward Vercelli, he eventually settled in Embrun to establish the local episcopate.
Life and ministry
After receiving instructions from the Pope, Marcellinus moved through the Alpine regions to evangelize the local populations. He traveled from the coast toward Vercelli, where he eventually parted ways with his companions. While his associate Vincent became the bishop of Digne, Marcellinus remained in Embrun, where he was appointed as its inaugural bishop in 354 AD.
Veneration
Recognized as a saint, he is commemorated in the Catholic, Anglican, and Orthodox traditions. His feast day is observed annually on April 20. He is remembered for his missionary work and for establishing the ecclesiastical foundation of the Embrun region.
