It is not uncommon that people under the influence of the New Age Movement and Hollywood movies ask about the possibility of another or previous life or other lives for the soul. Catholic Christianity and all orthodox Christian faith communities have always found in the Word of God clear revelation of the unique nature of this life, of individual death and a definitive judgment for the soul.
2 Cor 5:10: The lives of all of us are to be revealed before the tribunal of Christ so that each one may receive his recompense, good or bad, according to his life in the body.
Heb 9:27-28: Just as it is appointed that human beings die once, and after this the judgment, so also Christ offered once to take away the sins of many, will appear a second time, not to take away sin but to bring salvation to those who eagerly await him.
The Catechism of the Catholic Church states, “Death is the end of man’s earthly pilgrimage, of the time of grace and mercy which God offers him so as to work out his earthly life in keeping with the divine plan, and to decide his ultimate destiny. When ‘the single course of our earthly life’ is completed, we shall not return to other earthly lives: ‘It is appointed for men to die once.’ There is no “reincarnation” after death” (§1013).
