Is this new short book professor Moltmann approaches modern theology in two ways. The first part is chronological, and traces course of theology through the twentieth century, starting from the legacy left to it by the nineteenth century. In particular he highlights the related quests for secular relevance and Christian identity, both carried on in an "ecumenical age",
The second part looks at four different specific realizations of these quests by modern theologians: existentialist theology represented by Rudolf Bultmann and the problem of history; transcendental theology represented by Rahner and the problem of anthropocentrism; cultural theology represented by Paul Tillich and the religious interpretation of the secular world; and political theology.
