St. Paul allegedly engages in this activity in Second Timothy for the benefit of Onesiphorus, while Judas Machabeus engaged in this practice on behalf of comrades who had been found with idols of Jamnia. In the Eastern Orthodox Church, this practice is associated with Koliva, a type of ceremonial bread, and takes place at a special church service called the Panikhida. A person for whose benefit this practice is done may be listed as a diptych during Mass, and evidence that early Christians engaged in this activity includes monumental inscriptions left in Catacombs. Catholics often engage in this practice on behalf of a relative in Purgatory.
