"The ruler should be discreet in keeping silence, profitable in speech; lest he either utter what ought to be suppressed or suppress what he ought to utter. For, as incautious speaking leads into error, so indiscreet silence leaves in error those who might have been instructed. For often improvident rulers, fearing to lose human favour, shrink timidly from speaking freely the things that are right; and, according to the voice of the Truth, serve unto the custody of the flock by no means with the zeal of shepherds, but in the way of hirelings; since they fly when the wolf comes if they hide themselves under silence."
Saint Gregory the Great
