Ashes to Ashes, Dust to Dust

Now if anyone has ventured to some European church one will find bones, skin, vials of blood, and various body parts from Saints. They are relics. Even parts of these things hang around necks, in scapulas, etc.

Today the Vatican ruled that ashes cannot be scattered about or kept say on you bedside. As the Guardian reports:

Catholics are forbidden from keeping the ashes of cremated loved ones at home, scattering them, dividing them between family members or turning them into mementoes, the Vatican has ruled. Ashes must be stored in a sacred place, such as a cemetery, according to instructions disclosed at a press conference in Rome on Tuesday.

So what does one do with all those loose body parts floating around? If one is turned into basic chemicals why no fertilize the lilies in the field? What of say Joan of Arc, ashes scattered by the English.
