I believe that 2011 will bring a new schism into evangelical and popular Christianity. Being familiar with these definitions will help in the conversation:
Universalism is the general belief that all will be saved, regardless of religious beliefs. The Muslim and the Christian are on the same basic path—and for universalists all will be saved.
Universalism needs to be distinguished from pluralism (though as I have sketched “universalism” above there is precious little difference). Pluralism focuses on the legitimacy of each religion and belief system and that each of them prepares a person for final existence with God. For pluralists, there’s no unique saving place for Jesus Christ.
Christian universalism is a bit different: Christian universalism denies pluralism and balder forms of universalism by contending that all can or will be saved, but only through the saving work of Jesus Christ. While many who advocate this fail to recognize that those in other religions simply don’t believe such a thing, and in fact may say they don’t want to be saved through Christ, the Christian universalist confidently trots out the idea that whether they know it or not, God saves through Jesus Christ. But the big point here is that all can and will be saved through Christ.
Evangelical universalism is newer on the block and argues that God saves exclusively through Christ and that those who deny Christ, or who have not heard of Christ, or who have rejected God’s natural revelation to them, will be judged and will experience hell. In other words, these folks believe in hell—though they believe “less” (or as they might say “more”) than the traditionalist. But they believe hell is not eternal but instead temporary and once one has experienced judgment for one’s sins one will have, by the grace of God and through the merits of Christ, the opportunity to respond to the Gospel—and this news is so good and God’s offer so gracious that eventually hell will be emptied and all will find redemption in Christ to enjoy God’s salvation forever.
There is yet another version: annihilationism or conditional immortality. This view is traditional in its appeal to evangelism and to the gospel of salvation through Christ alone—it is an exclusive claim—and that those who don’t respond to the Gospel will be judged and will experience hell, but that eventually their punishment will run out and they will be utterly destroyed and annihilated and cease from existence. Here one has both a traditional view of hell and, at the same time, some kind of correlation between temporary sins—say 75 years of utter rejection of all things pertaining to what they know of God and Christ—and the experience of justice. When that justice runs its course that person will be utterly extinguished. Instead of an eternal consciousness of separation from God, these folks believe only in eternal consequences.
Then there’s the traditional view: those who reject Christ, and some believe God’s mercy will be wide enough to include those who have never heard of Christ but have responded to the light they have comprehended (inclusivism)—and there’s latitude here for variations of several sorts—will be judged on the basis of that light. For traditionalists and some inclusivists their number is few so that billions who have not responded to Christ will suffer eternal and conscious separation from God. Some inclusivists would contend that many, if not most, humans will be finally saved.
