The Apologists
Who Pius I of Rome was
Tenth bishop of Rome, and the one an early Roman source (the Muratorian Canon) links to the Shepherd of Hermas: “Hermas wrote the Shepherd very recently, in our times, in the city of Rome, while his brother Pius, the bishop, was sitting in the chair.” Under him Marcion made his decisive break with the Roman church (c. 144), and Justin Martyr taught in the city. About fifteen years of a church entering its intellectual maturity.
Also listed in the bishops of Rome.
