Clement of Alexandria:
“I wonder how some dare to call themselves ‘perfect’ and ‘Gnostics.’ They are inflated and boastful, viewing themselves above the apostle. For Paul himself acknowledged about himself: ‘Not that I have already attained or am already perfect.’”
Barnabas:
“The whole past time of your faith will profit you nothing, unless now in this wicked time we also withstand coming sources of danger.”
