Here is a reference to Mortalism:
Mortalism
Thomson (2008), Bodies of thought: science, religion, and the soul in the early Enlightenment, p. 42, For mortalists the Bible did not teach the existence of a separate immaterial or immortal soul and the word 'soul' simply meant 'life'; the doctrine of a separate soul was said to be a Platonic importation..
Kries 1997, p. 97: ‘In Leviathan, soul and body are one; there are no "separated essenses" [sic]; death means complete death – the soul, merely another word for life, or breath, ceases at the death of the body. This view of the soul is known as Christian mortalism – a heterodox view held, indeed, by some sincere believers and not unique to Hobbes.’
Hick (1994), Death and eternal life, p. 211, christian mortalism – the view that the soul either sleeps until the Day of Judgment, or is annihilated and re-created.
Fudge & Peterson 2000, p. 173 -1: ‘the belief that according to divine revelation the soul does not exist as an independent substance after the death of the body’
Almond 1994, p. 38: …‘mortalist views – particularly of the sort which affirmed that the soul slept or died – were widespread in the Reformation period. George Williams has shown how prevalent mortalism was among the Reformation radicals.’
We are mortal.
