It's Murder!

Slander is a form of murder.  We have three kinds of life: spiritual, which consists in God's grace, corporeal, which depends on the body and soul, and social, which consists in our good name.  Sin deprives the first kind of life, death takes away the second, and slander the third.  

By a single stroke of his tongue the slanderer usually commits three murders.  He kills his own soul and the soul of anyone who hears him by an act of spiritual homicide and takes away the social life of the man he slanders. 

St. Frances de Sales
