The terms 'transcendence' and 'immanence' are often used casually and as self-evident. The spatial imagery contained in their meaning determines the way they are understood and used: as opposites, like 'there' and 'here'. As a consequence, the two concepts are seen as mutually exclusive when applied to God's being and to his activity and presence in our world and in our history. This view on the relationship between God and world is characteristic not only of deism and pantheism, but also of theism. However, in the view of Thomas Aquinas, such an opposition cannot adequately capture the central tenets of the Christian faith. This book explores Aquinas' thought on transcendence and immanence in his discussions of creation, analogy, the Trinity, grace and Christ, and offers interpretations in which God's transcendence and his immanence do not exclude but imply one another. The papers contained in this volume were originally presented at the third international conference of the Thomas Instituut at Utrecht in 2005.
