Significant attention should be given to the primary symbols of the Catholic funeral liturgy, as stated in the Order of Christian Funerals and its commentaries. The paschal candle and sprinkling with holy water are primary symbols of baptism and should be used during the funeral Mass. However, the pall is not used. Photos and other mementos may be used at the vigil, but are not appropriate for the Mass. During the Mass, the cremated remains should be treated with the same dignity and respect as the body.
They are to be sealed in a “worthy vessel.” They may be carried in procession and / or placed on a table where the coffin normally would be with the Easter candle nearby. The body is always laid to rest with solemnity and dignity. So too, the Order of Christian Funerals provides for the interment of cremated remains (Order of Christian Funerals, #428).
