Theology is the study of one or more religions. ("Theo-" is "God" in Greek and "-logy" is study)

It is not a study of the history of a religion. It is a study of what things precisely mean in one religion, or between religions. People who work in Theology are theologists or theologians. They look carefully at the Holy Texts and at other theologians' work. They often also give moral advice.
