mortalist
Mortalism is a theological belief that the soul is not immortal but dies with the body and will be resurrected at some future date. This contrasts with the traditional view of an inherently immortal soul that survives death. Mortalists believe that the state of the soul after death is unconsciousness until a general resurrection. This doctrine holds that immortality is a gift bestowed by God at the resurrection, rather than an inherent quality of the soul.
The belief in mortalism has appeared in various forms throughout history and across different religious traditions.
The opposite of mortalism is psychopannychism, which posits that the soul sleeps between death and resurrection,
