When cremation of the body is chosen, the Church still prefers that the body be cremated after the Funeral, thus allowing for the presence of the body at the Funeral Mass. When circumstances require it, however, cremation and committal may take place even before the Funeral liturgy. As mentioned above, most of the usual rites which are celebrated in the presence of the body of the deceased may also be celebrated in the presence of the cremated remains. The primary symbols of the Roman Catholic Funeral Liturgy are retained even when the funeral liturgy is celebrated in the presence of the cremated remains. The cremains may be carried in procession and/or placed on a table where the casket normally would be. Photographs and other mementos may be used at the vigil, in the narthex (entrance to the Church), and at the cemetery, but are not appropriate at the Mass.
