The relation between science and religion has become so popular after the collapse of positivistic mentality. In this paper, I have brought forward the approach of process philosophy to the issue of science and religion and I have also delineated the model of Barbour, which describes the relation between science and religion. Basically I have brought out what Barbour as well as process philosophy think about science and religion. Then occasionally I have compared Barbour with some contemporary thinkers. I have reached the conclusion that science and religion are the necessary part of the holistic world-view.
