How did Origen distinguish his belief in preexistent souls from reincarnation?

Origen distinguished his belief in the preexistence of souls from reincarnation by explicitly rejecting the concept of transmigration, which involves the movement of rational souls into animal bodies.1

While Origen speculated that souls fell from their original state to varying degrees—becoming angels, humans, or devils based on their distance from God—he maintained that these souls were created as rational and spiritual beings. His theological framework emphasized that the material world serves as a place of discipline and education, where souls are restored to their original blessedness through redemption. Unlike reincarnation, which often implies a cycle of rebirths based on karma or fate, Origen’s view was rooted in the exercise of free will and the remedial, loving nature of God, who seeks to restore all creatures to himself.1
