Karl Rahner (1904-1984) was one of the most significant theological voices of the twentieth century. For many his theology symbolizes the Catholic Church's entry into modernity. Part of his enduring appeal lies in his ability to reflect on a variety of issues in theology and spirituality and direct this plurality into a few basic convictions. In addition to the main themes of Rahner's work, this Companion assesses his significance for contemporary theology through dialogues with many current concerns including: religious pluralism, spirituality, postmodernism, ecumenism, ethics and developments in political and feminist theologies.
