Pope Fabian
According to Christian historians, during the consulship of the Emperor Decius and Vettius Gratus (250 AD), Pope Fabian sent out seven bishops from Rome to Gaul to preach the Gospel: Gatianus to Tours, Trophimus to Arles, Paul to Narbonne, Saturnin to Toulouse, Denis to Paris, Austromoine to Clermont, and Martial to Limoges. A community of Christians had already existed for many years in Lyon, where Irenaeus had been bishop.
