When the choice has been made to cremate a body, it is recommended that the cremation take place after the funeral liturgy. The Church prefers that the body of the deceased be present for the funeral rites. The cremated remains should be treated with the same respect given to the human body from which they come, which includes final disposition. The proper disposition for the cremated remains is to be buried or entombed at a cemetery or mausoleum in a manner that will provide a guarantee of perpetual care.
The practice of scattering cremated remains or keeping them in the home of a relative or friend of the deceased is not considered reverent disposition, and is therefore not approved by the Church.
For additional information on cremation, consult your Catholic pastor or talk with a Catholic Cemeteries and Funeral Homes Counselor.
