Care of Cremated Remains
The burial directives of the Catholic Church call attention to the care taken of the cremated remains. They should be treated with the same respect we give to the body of the deceased. The remains are to be placed in a worthy vessel, which then is carried and transported with the same respect and attention given to a casket carrying a body.
The cremated remains should be buried in a grave or entombed in a mausoleum or columbarium [a cemetery vault designed for urns containing ashes of the dead]. 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.
