Preexistence

Pre-existence, preexistence, beforelife, or premortal existence refers to the belief that each individual human soul existed before mortal conception, and at some point before birth enters or is placed into the body. Concepts of pre-existence can encompass either the belief that the soul came into existence at some time prior to conception or the belief that the soul is eternal. Alternative positions are traducianism and creationism, which both hold that the individual human soul does not come into existence until conception. It is to be distinguished from preformation, which is about physical existence and applies to all living things.

Ancient Greek thought and Islam affirm pre-existence, but it is generally denied in Christianity.

Plato believed in the pre-existence of the soul, which tied in with his innatism. He thought that we are born with knowledge from a previous life that is subdued at birth and must be relearned. He saw all attainment of knowledge not as acquiring new information, but as remembering previously known information. Before we were born, we existed in a perfect world where we knew everything.

A concept of pre-existence was advanced by Origen, a second and third-century church father. Origen believed that each human soul was created by God at some time prior to conception. Church Fathers Tertullian and Jerome held to traducianism and creationism, respectively, and pre-existence was condemned as heresy in the Second Council of Constantinople in AD 553.

Origen quoted as evidence for his position:

For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth; It was said unto her, The elder shall serve the younger. As it is written, Jacob have I loved, but Esau have I hated. What shall we say then? Is there unrighteousness with God? God forbid.
