This essay examines the relationship between scientific and religious knowledge as reflected in theological works written in the fourteenth century. It argues that later works differ from earlier, classic works of theology partly as a result of developments in the field of astronomy. I contend that the theology that previously informed astronomy itself underwent theoretical adjustment and transformation under the influence of new conceptual trends in the science of astronomy. I also maintain that the new theology was conceptualized as a limited, rather than a comprehensive, field of knowledge.
