Envy is sadness at another’s good, and joy at another’s evil. What rust is to iron, what moths are to wool, what termites are to wood, that is what envy is to the soul: the assassination of brotherly love. Envy manifests itself in discord, hatred, malicious joy, backbiting, detraction, imputing evil motives, jealousy, and calumny.
–Blessed Fulton Sheen (1895-1979)
