The 20th century experienced an explosion of publicly available information concerning the wider religious life of humanity, as a result of which the older Western assumption of the manifest superiority of Christianity ceased to be plausible for many Christians. Early 20th-century thinkers such as Rudolf Otto, who saw religion throughout the world as a response to the Holy, and Ernst Troeltsch, who showed that, socioculturally, Christianity is one of a number of comparable traditions, opened up new ways of regarding the other major religions.
During the 20th century most Christians adopted one of three main points of view. According to exclusivism, there is salvation only for Christians. This theology underlay much of the history outlined above, expressed both in the Roman Catholic dogma extra ecclesiam nulla salus (“outside the church no salvation”) and in the assumption of the 18th- and 19th-century Protestant missionary movements. The exclusivist outlook was eroded within advanced Roman Catholic thinking in the decades leading up to the Second Vatican Council and was finally abandoned in the council’s pronouncements. Pope John Paul II’s outreach to the world’s religions may be seen as the practical application of the decisions of Vatican II. Within Protestant Christianity there is no comparable central authority, but most Protestant theologians, except within the extreme fundamentalist constituencies, have also moved away from the exclusivist position.
Since the mid-20th century many Roman Catholics and Protestants have moved toward inclusivism—the view that, although salvation is by definition Christian, brought about by the atoning work of Christ, it is nevertheless available inKarl Rahner expressed the inclusivist view by saying that good and devout people of other faiths may, even without knowing it, be regarded as “anonymous Christians.” Others have expressed in different ways the thought that non-Christians also are included within the universal scope of Christ’s salvific work and their religions fulfilled in Christianity.
principle to all human beings, whether Christian or not. The Roman Catholic theologianThe third position, which appealed to a number of individual theologians, was pluralism. According to this view, the great world faiths, including Christianity, are valid spheres of a salvation that takes characteristically different forms within each—though consisting in each case in the transformation of human existence from self-centredness to a new orientation toward the Divine Reality. The other religions are not secondary contexts of Christian redemption but independent paths of salvation. The pluralist position is controversial in Christian theology, because it affects the ways in which the doctrines of the person of Christ, atonement, and the Trinity are formulated.
Christians engage in dialogue with the other major religions through the World Council of Churches’ organization on Dialogue with People of Living Faiths and Ideologies and through the Vatican’s Secretariat for Non-Christians, as well as through a variety of extra-ecclesiastical associations, such as the World Congress of Faiths. There is a National Council of Churches of Christ in the United States, and practically every state has its own similar state-level organization. A multitude of interreligious encounters have taken place throughout the world, many initiated by Christian and others by non-Christian individuals and groups.
