An overview of several philosophical issues that arise from the recent growth of interest in the relationships between science (especially natural science) and theology (especially Christian thought). The interactions between theology and science are complex, and often highly contextual in nature. This makes simple typologies of their interaction rather dubious. There are some similarities between religion and science, including the difficulty of defining them. Concerns about the use and meaning of language, and issues of realism and anti-realism, are found in both areas of thought. Epistemology is important to both areas, and there is increasing acceptance of differing epistemologies not only in religion and science, but also within the various scientific disciplines. One central issue is the question of legitimate influence between science and theology given their aims and methods. Another issue surrounds the question of naturalism in natural science. Also important to note is the variety of god-concepts at work in the current dialogue between science and theology.
