Book excerpt: Originally published in 1949 and then revised in 1979, this comprehensive introduction to systematic theology has well served countless students and pastors for more than half a century. In this paperback edition it will continue to instruct serious students of the Bible and theology. Following two introductory chapters delineating the nature, necessity, possibility, and divisions of theology, Henry Clarence Thiessen systematically address a wide range of subjects in eight major sections -- Theism, Bibliology, Theology, Anthropology, Soteriology, Ecclesiology, Angelology, and Eschatology. Also included are two specialized indexes for further study -- an Index of Subjects and an Index of Scriptural References that includes over 4,000 entries.
