“THE episcopate… did not, as a class or order of men, play a good part in the troubles consequent upon the Council; and the laity did… [I]t was by the faithful people, under the lead of Athanasius and the Egyptian bishops, and in some places supported by their Bishops or priests, that the worst of heresies was withstood and stamped out of the sacred territory.”

(Saint John Henry Newman, “The Orthodoxy of the Body of the Faithful during the Supremacy of Arianism“)

“But some one will ask, How is it then, that certain excellent persons, and of position in the Church, are often permitted by God to preach novel doctrines to Catholics?… Let us listen, then, to Holy Moses… [who] writes thus in Deuteronomy… For the Lord, your God, tries you, to know whether you love Him with all your heart and with all your soul.” 

(Saint Vincent of Lerins, Commonitory For the Antiquity and Universality of the Catholic Faith Against the Profane Novelties of All Heresies, x)
