“ All graver faults extend the sphere for diligence in watchfulness proportionably to the magnitude of the danger; in order that we may withdraw not only from the faults, but from the means through which they have being. ”

“ Indeed, if he shall have ejected a demon, [7] let him not congratulate himself on his faith, for he has not ejected an enemy; he ought to have had his prayer easily granted by one whom he is daily feeding. ”
