avarice breeds envy, a worm that is always gnawing, letting the avaricious enjoy neither their own nor anyone else's good.
St. Catherine of SienaThere is no sin nor wrong that gives man such a foretaste of Hell in this life as anger and impatience.
St. Catherine of SienaYou are obliged to love your neighbor as yourself, and loving him, you ought to help him spiritually, with prayer, counseling him with words, and assisting him both spiritually and temporally, according to the need in which he may be, at least with your goodwill if you have nothing else.
