Some priests refuse to anoint a dead body and offer what is traditionally called the Sacramental Last Rites which includes the apostolic pardon.
In the olden days, a priest full of pastoral solicitude for the living and the dead, would at least offer a conditional Last Rites to a presumed dead body including absolution, Apostolic Pardon and Anointing. The theology was that no one was quite sure how long it takes for the living immortal soul to depart the dead mortal bod, so one was not scrupulous about not offering the Sacramental Last Rites.
This miracle of sorts clinches the case for me! Offer the Sacramental Last Rites to the presumed Dead 💀!!!! They could end up being the Walking Dead, O my!
