The Catholic Church earnestly recommends that the pious custom of burying the bodies of the dead be observed; it does not, however, forbid cremation unless it has been chosen for reasons which are contrary to Christian teaching (Code of Canon Law No. 1176, 3).
Although cremation is now permitted by the Church, it does not enjoy the same value as burial of the body. The Church clearly prefers and urges that the body of the deceased be present for the funeral rites, since the presence of the human body better expresses the values which the Church affirms in those rites (Order of Christian Funerals no. 413).
The cremated remains of a body should be treated with the same respect given to the human body from which they come. This includes the use of a worthy vessel to contain the ashes, the manner in which they are carried, and the care and attention to appropriate placement and transport, and the final disposition. The cremated remains should be buried in a grave or entombed in a mausoleum or columbarium. The practice of scattering cremated remains on the sea, from the air, or on the ground, or keeping cremated remains in the home of a relative or friend of the deceased are not the reverent disposition that the Church requires (cf Order of Christian Funerals # 417).
