The relations between physics and theology are surprisingly cordial at present; the relations between biology and theology are more difficult. Astrophysics and nuclear physics are describing a universe "fine-tuned" for life, while evolutionary and molecular biology seem to be discovering that the history of life is a random walk with struggle and chance, driven by selfish genes. Evolutionary theory has proved quite problematic in several respects. Struggle and suffering, and life renewed in the midst of its death and perishing, are central themes in Christianity. Although biologists are typically uncertain whether life has arrived on Earth by divine intention, they are almost unanimous in their respect for life.
