Unlike its discipline regarding sacraments, the Catholic Church does not exclude anyone from receiving sacramentals, such as the placing of ashes on the head, even those who are not Catholics and perhaps not even baptized. Even those who have been excommunicated and are therefore forbidden to "celebrate" sacramentals are not forbidden to "receive" them. After describing the blessing, the rite of Blessing and Distribution of Ashes (within Mass) states: "Then the Priest places ashes on the heads of all those present who come to him." The Catholic Church does not limit distribution of blessed ashes to within church buildings and has suggested the holding of celebrations in shopping centres, nursing homes, and factories. Such celebrations presume preparation of an appropriate area and include readings from Scripture (at least one) and prayers, and are somewhat shorter if the ashes are already blessed.
