Every Saint needs a miracle. That’s how the Church decides you are a Saint. “Don’t drink the water, drink beer” warned Saint Arnold of Metz , concerned about the dangers of drinking impure water, while the boiled and processed water used for beer was a safer alternative.
According to the legend he ended a plague when he submerged his crucifix into a brew kettle and persuaded people to drink only beer from that “blessed” kettle. The story of the miracle kettle of beer spread and eventually Arnold was canonized by the Catholic Church for it.
