A patron saint is a holy man or woman canonized by the Church whose life and heavenly intercession are considered especially powerful for particular needs, groups, or situations. Catholics ask patron saints to intercede — to pray to God on their behalf — drawing on the doctrine of the Communion of Saints.
To ask for a patron saint's intercession, Catholics typically pray directly to the saint, saying something like: "Camillus de Lellis, pray for us." You may also light a candle, attend Mass on their feast day, or make a novena — nine days of consecutive prayer — asking for their help before a particular need.
