Man liveth not by bread only. The words were spoken of the manna. (Deuteronomy viii. 3.) The sense in this place is, that man’s life may be supported by any thing, or in any manner, as it pleaseth God. (Witham) — St. Gregory upon this passage says: if our divine Redeemer, when tempted by the devil, answered in so mild a manner, when he could have buried the wicked tempter in the bottom of hell, ought not man, when he suffers any thing from his fellow man, rather to improve it to his advantage, than to resent it to his own ruin. Man consists of soul and body; his body is supported by bread, his soul by the word of God; hence the saying, “Lex est cibus animę.” (Mat. Polus.)
