In addition, the desire or need for cremation MUST NOT originate from a denial of bodily resurrection.
The Church had a general condemnation of cremation because several heretical groups that used the practice specifically as a denial of the resurrection.
( Henry VIII had Katherine Howard’s body dissolved in lime and the lime thrown into the Thames, specifically to deny her bodily resurrection)
That heresy has, fortunately, lapsed. And, as such, the Church permits cremation for economic, health or reasons of civil law.
