Judaism
Because Judaism is by origin and nature an ethnic religion, salvation has been primarily conceived in terms of the destiny of Israel as the elect people of Yahweh (often refered to as “the Lord”), the God of Israel. It was not until the 2nd century bce that there arose a belief in an afterlife, for which the dead would be resurrected and undergo divine judgment. Before that time, the individual had to be content that his posterity continued within the holy nation. But, even after the emergence of belief in the resurrection of the dead, the essentially ethnic character of Judaism still decisively influenced soteriological thinking. The apocalyptic faith, which became so fervent as Israel moved toward its fateful overthrow by the Romans in 70 ce, conceived of salvation as the miraculous intervention of the Lord or his messiah (literally “anointed one”) in world affairs. This saving act would culminate in the Last Judgment delivered on the nations that oppressed Israel and Israel’s glorious vindication as the people of God. From the end of the national state in the Holy Land in 70 ce, Jewish religion, despite the increasing recognition of personal significance, has remained characterized by its essential ethnic concern. Thus, the Exodus from Egypt has ever provided the typal imagery in terms of which divine salvation has been conceived, its memory being impressively perpetuated each year by the ritual of the Passover. The restoration of the holy nation, moreover, always has been linked with its Holy Land, and Hebrew literature, both in biblical and later forms, has lovingly described the establishment of a New Jerusalem and a new Temple of the Lord, whether it be in this world or in some new cosmic order. Into this new order the rest of humankind, repentant and purified, will be incorporated, for the original promise made to the patriarch Abraham included all within the divine blessing. In the Book of Zechariah, the ultimate salvation of humankind is graphically envisaged: the Gentiles, in company with the Jews, will return to serve God in an ideal Jerusalem.
Christianity
Christianity’s primary premise is that the incarnation and sacrificial death of Jesus Christ formed the climax of a divine plan for humanity’s salvation. This plan was conceived by God consequent on the Fall of Adam, the progenitor of the human race, and it would be completed at the Last Judgment, when the Second Coming of Christ would mark the catastrophic end of the world. This soteriological evaluation of history finds expression in the Christian division of time into two periods: before Christ (bc) and anno Domini (ad)—i.e., the years of the Lord. This classification of time has been increasingly superseded since the late 20th century by the periods before the Common Era (bce) and Common Era (ce), respectively.
The evolution of the Christian doctrine of salvation was a complicated process essentially linked with the gradual definition of belief in the divinity of Jesus of Nazareth. In Christian theology, therefore, soteriology is an integral part of what is termed Christology. Whereas the divinity of Jesus Christ has been the subject of careful metaphysical definition in the creeds, the exact nature and mode of salvation through Christ has not been so precisely defined. The church has been content to state in its creeds that Christ was incarnated, crucified, died, and rose again “for us men and for our salvation.”
The basic tenets of Christian soteriology may be summarized as follows: humanity deserves damnation by God for the original sin, which it inherits by descent from Adam; each human also deserves damnation for his own actual sin. But because sin is regarded as also putting humans in the power of the Devil, Christ’s work of salvation has been interpreted along two different lines. Thus, his crucifixion may be evaluated as a vicarious sacrifice offered to God as propitiation or atonement for human sin. Alternatively, it may be seen as the price paid to redeem humanity from the Devil. These two ways of interpreting the death of Christ have provided the major themes of soteriological theory and speculation in Christian theology. Despite this fluidity of interpretation, belief in the saving power of Christ is fundamental to Christianity and finds expression in every aspect of its faith and practice.
Islam
Muhammad regarded himself as “a warner clear” and as the last and greatest of a line of prophets whom Allah (in Arabic, Allāh: God) had sent to warn his people of impending doom. Although the word najāt (Arabic: “salvation”) is used only once in the Qurʾān (the holy book of Islam), the basic aim of Islam is salvation in the sense of escaping future punishment, which will be pronounced on sinners at the Last Judgment. Muhammad did teach that Allah had predestined some humans to heaven and others to hell, but the whole logic of his message is that submission to Allah is the means to salvation, for Allah is merciful. Indeed, faithful submission is the quintessence of Islam, the word islām itself meaning “submission.” Although in his own estimation Muhammad was the prophet of Allah, in later Muslim devotion he came to be venerated as the mediator between God and humanity, whose intercession was decisive.
