On Humility as a Foil against the Devil

“The devil appeared to a certain brother, transformed into an angel of light, and said to him, ‘I am the angel Gabriel and I am sent unto thee.’ But the brother said, ‘Consider well if you were not in fact sent to some other: for I am not worthy that an angel should be sent to me.’ And the devil was no more seen.”
