For Hegel, thought is not philosophical if it is not also religious. Both religion and philosophy have a common object and share the same content, for both are concerned with the inherent unity of all things. Hegel's doctrine of God provides the means for understanding this fundamental relationship. Although Hegel stated that God is absolute Spirit and Christianity is the absolute religion, the compatibility of Hegel's doctrine of God with Christian theology has been a matter of continuing and closely argued debate. Williamson's book provides a significant contribution to this ongoing discussion through a systematic study of Hegel's concept of God. The book proceeds by investigating theism, atheism, pantheism, and panentheism as descriptions of Hegel's concept. It rejects the view that Hegel's doctrine so differs from Christian theology so as to be empty of religious content and thereby highlights some important considerations in contemporary theology.

"It provides an account of the criticism of religion by key Enlightenment thinkers such as Voltaire, Lessing, Hume, and Kant. This is followed by an analysis of how the Romantic thinkers, such as Rousseau, Jacobi, and Schleiermacher, responded to these challenges. For Hegel, the views of these thinkers from both the Enlightenment and Romanticism tended to empty religion of its content. The goal that he sets for his own philosophy of religion is to restore this lost content. " -- back cover.

In his Lectures on the Philosophy of Religion, Hegel treats the religions of the world under the rubric "the determinate religion." This is a part of his corpus that has traditionally been neglected since scholars have struggled to understand what philosophical work it is supposed to do. In Hegel's Interpretation of the Religions of the World, Jon Stewart argues that Hegel's rich analyses of Buddhism, Hinduism, Zoroastrianism, Judaism, Egyptian and Greek polytheism, and the Roman religion are not simply irrelevant historical material, as is often thought. Instead, they play a central role in Hegel's argument for what he regards as the truth of Christianity. Hegel believes that the different conceptions of the gods in the world religions are reflections of individual peoples at specific periods in history. These conceptions might at first glance appear random and chaotic, but there is, Hegel claims, a discernible logic in them. Simultaneously, a theory of mythology, history, and philosophical anthropology, Hegel's account of the world religions goes far beyond the field of philosophy of religion. The controversial issues surrounding his treatment of the non-European religions are still very much with us today and make his account of religion an issue of continued topicality in the academic landscape of the twenty-first century.

Theological, cultural, and epistemological issues of the time. 'The Concept of Religion' sets forth a speculative definition of religion and discusses the experience, concept, knowledge, and worship of God.
