First, the orthodox view is commonly interpreted to be the belief that punishment for the wicked is everlasting and that it is punitive, not redemptive. Because the Bible reveals that God is a God of love and grace, a tension has developed between the concepts of a loving God and of a righteous God who demands absolute justice of the wicked. It is generally conceded, however, that a strict orthodoxy provides a literal everlasting punishment for the wicked.
Second, a view of hell as metaphorical, that is, somewhat non-literal and less specific than the orthodox view, has also attracted many followers. Usually it is conceded that those who are wicked will never be redeemed and restored to a place of blessing in eternity, but the scriptural accounts of their suffering and divine judgment are taken in a less-than-literal understanding.
Third, the Roman Catholic view sees hell as purgatorial, that is, hell has an ante-chamber called purgatory, a place of divine cleansing from which some, at least, will eventually emerge as redeemed and be among the blessed of God. Generally speaking, this view requires that all must go through a period of purgation in which their unconfessed sins are judged and punishment inflicted. Though it may be extensive and continue over a period of time, ultimately, many will be restored to a place of grace and bliss, though others will be damned eternally.
Fourth, the view of hell as a conditional or temporary situation for the wicked has been advocated by many who find a contradiction between the doctrines of everlasting punishment and of a God of love and grace. As a result, they explain that hell is either temporary, in the sense that immortality is conditional and only the righteous will be raised, or that it is redemptive, in the sense that whatever suffering there may be after this life because of sin will end up in the wicked being redeemed and restored to a place of blessing. In other words, conditional immortality or annihilation lessens the severity and the extent of everlasting punishment, while in universalism, all are eventually saved.
