St. Augustine of Hippo is the patron of brewers because of his conversion from a former life of loose living, which included parties, entertainment, and worldly ambitions. His complete turnaround and conversion has been an inspiration to many who struggle with a particular vice or habit they long to break.
So, anyone here struggling with a particular vice or nasty habit? I have given all mine up, mainly from lack of energy. Something I like about St Augustine of Hippo is the text he had on the wall of his room: "Here we do not speak evil of anyone."
Maybe that's where the Gautama Buddha got it from.
