Brewer's: Bell, Book, and Candle
A ceremony in the greater excommunication introduced into the Catholic Church in the eighth century. After reading the sentence a bell is rung, a book closed, and a candle extinguished. From that moment the excommunicated person is excluded from the sacraments and even divine worship.
“Bell, book, and candle shall not drive me back.” —Shakespeare: King John, iii. 3.
