In Christian theology, universal reconciliation (also called universal salvation, Christian universalism, or in context simply universalism) is the doctrine that all sinful and alienated human souls—because of divine love and mercy—will ultimately be reconciled to God. The doctrine has been rejected by most mainstream Christian churches, which tend to maintain at least the possibility that many are not saved, but it has received support from many prestigious Christian thinkers as well as many groups of Christians. It has been argued that the Bible itself has a variety of verses that seem to support a plurality of views. Universal salvation may be related to the perception of a problem of Hell, standing opposed to ideas such as endless conscious torment in Hell, but may also include a period of finite punishment similar to a state of purgatory. Believers in universal reconciliation may support the view that while there may be a real "Hell" of some kind, it is neither a place of endless suffering nor a place where the spirits of human beings are ultimately "annihilated" after enduring the just amount of divine retribution. The concept of reconciliation is related to the concept of salvation—i.e., salvation from spiritual and eventually physical death—such that the term "universal salvation" is functionally equivalent. Universalists espouse various theological beliefs concerning the process or state of salvation, but all adhere to the view that salvation history concludes with the reconciliation of the entire human race to God. Many adherents assert that the suffering and crucifixion of Jesus Christ constitute the mechanism that provides redemption for all humanity and atonement for all sins. Modern Unitarian Universalism emerged in part from the Universalist Church but, being a non-creedal faith, it holds no official doctrinal positions. Universal reconciliation, however, remains a popular viewpoint among many of its congregations and individual believers, including many who have not associated with the Universalist Church. An alternative to universal reconciliation is the doctrine of annihilationism, often in combination with Christian conditionalism. Some Christian leaders, such as influential German theologian Martin Luther, have hypothesized other concepts such as "spiritual mortalism" or "soul death". Biblical background As David Fisher, a bishop and professor of philosophy has put it, "In the final analysis, the question of salvation is always an inquiry into the balancing of human free will with God's mercy and forgiveness." The Bible itself has, as referred to before, a variety of verses on
