St. Peter Chrysologus, to Eutyches: “We exhort you, honourable brother, to attend with docility in all things to what shall be prescribed to you by the most blessed Pope of the Roman city, since BLESSED PETER, WHO IN HIS OWN SEE LIVES AND PRESIDES, grants the knowledge of the true faith to those that seek it.” (S. Petrus Chrys. Ep. ad Eutycheten.)
