Incorruptibility is the property of a body — usually a human body — that does not decompose after death. Such a body is sometimes referred to as incorrupt or incorruptible (adjective) or as an incorruptible (noun).Incorruptibility is seen as distinct from the good preservation of a body, or mummification. Incorruptible bodies are often said to have the Odour of Sanctity, a sweet smell.The incorrupt bodies of these saints are simply a living witness or proof to the truth of the Catholic religion as the one true faith from God, who has confirmed the testimony of the Church in the great miracles he has worked through it's saints.
