Medieval Christian philosophy inherited both the Platonic view of the soul as naturally immortal and the Christian insistence that immortality is ultimately participatory in God's eternal life. Pseudo-Dionysius frames this as God distributing "the power to live appropriately to each" — immortality as relational gift, not autonomous property. Aquinas then provided the dominant scholastic philosophical grounding: since the intellectual soul operates independently of any bodily organ, it cannot be corrupted by the body's dissolution, though it remains naturally ordered to embodiment. When separated from the body, the soul "will be perfectly assimilated to the intelligences that subsist apart, and will receive their influence in more copious streams."

What the primary sources show
God as the source of life distributed to all beings — immortality understood as participation in the divine power to live, not as an autonomous property of the soul apart from God.
On the nature of the soul, its immateriality, and its natural incorruptibility — Aquinas argues that since the intellectual soul operates independently of any bodily organ, it cannot be corrupted by the body's dissolution, but it remains naturally ordered to embodiment.
